Upgrade your interior

Are you getting bored with the classic colours and fabrics of your interior? Why not try looking for custom re-upholsterers to swap in your aftermarket parts?

A lot of cars today come with black and grey interiors and sometimes navy blue or a slight coloured cord finish. Some also have the slight variation in the fabric. These may look great at a closer look but when you are from a distance, you may notice that they are not that attractive at all.

Even as a car interior usually appears to a wide selection of motorists as it stands up to 20 years use, there is much that can be done to spice up the interior of your car. You can start having your seats upgraded. Many sports seats are available in the market today. However, these are somewhat difficult to track down rear seats to match as most aftermarket seats. Universal fit seats have an adapter rail that will match the car, whereas the rear seats have to be specific in size and must have precisely cut belt holes and release catches.

Using the new seats as base, you can get them without having the recovered or completely re-upholstered. Once you have swapped them in, you can earn bucks by having your old seats sold to your fellow car owner.

Re-upholstering is not an easy job. If you want to do it by yourself, it may take a week or two before you finally take advantage of the output. But if you want to have it finished at once, you should look for an experienced upholsterer.

On the other hand, you should also reckon with the materials of your new fabrics. Be careful with selecting the hard wearing fabric like leather. This material is great as it repels most stains from liquids. This is also easy to clean and is stretchable, as it fits flawlessly into your auto seats.

Aside from leather, you can also choose other fabrics such as heavy cotton, alacatra, and synthetic fibres. Make sure that these fabrics are properly stitched. They must not get a lot of abuse otherwise, you will suffer from a bad interior.

Upholstering is definitely a major activity that will result to major changes in your interior. Hence, it is always a part of a complete interior makeover that you must provide with ample time, effort, and money. This may also include the upgrade on door cards. You can remove the door furniture like the switches, handles, and catches. The door cards typically pushed on with studs and are warped as they are removed.

You can also upgrade the speakers. You can add up small colored panel that can radically transform your car’s appeal. Less is more it is.

New fabric trim can be simply stretched over the doorcard, holes from furniture that can be added and then you can affix the fabric to the door card, having a heavy duty carpet tape spread liberally over the backing surface to a keep them from stretching or a good quality fabric adhesive.

If you are using an adhesive, make sure that it won’t oose through the fabric otherwise, it will harden the fabric, making it scratchy to touch. You can pull the fabric over the edges. You can glue down the seam on the reverse of the door car then rely on the door furniture to avoid sagging.

The finishing touches, dials, dash board function, gear knob, and handbrake can be upgraded too so that they will blend in with the rest of your interior. All of these can represent your personality so get on your feet and be ready with all that these may cost.

Big power? Have a more powerful clutch!

Your vehicle’s capability to accelerate matters a lot. Hence, big power always requires a powerful clutch that will manage more effective and efficient shifting of gears.

Clutch takes engine power and puts it down through the drive shaft to the driven wheels but it also allows you to disengage the engine whilst performing a gear change. This kind of contact often requires a lot of grip and fast response. As, the more power there is, te harder it is for the clutch to operate.

Power is potentially lost if the clutch slips. Failing to make steady contact with the contact plate when the clutch was first released. Power clutches are usually designed with high friction surfaces and sometimes 2 or 3 contact plates.

Heavy duty race clutches have less feel and are practically on or off. Because of this, it may become hard to drive smoothly in traffic or pulling away smoothly on a hill, requiring a fair bit of leg muscle.

Clutch release spring is fairly heavier on most race clutches. A fast road power clutch makes more sense for road use though the high spec multi-plate race solution would seem the best, it is not that great to domestic driving for most vehicle types.

Most clutches have power ratings. If your engine’s output is greater than the rated power of the clutch, clutch slip is more likely experienced while you are accelerating. As a result, the clutch will wear out quickly.

What is clutch slip? A sudden surge of power can cause the clutch to lose grip. This will end up with failure in transferring power to the wheels. This is evidenced by a rise in the revs but not in the road speed. So do you now understand what clutch slip is? This can be compared to pulling a table cloth off a table and all the crockery still stay in place.

As you find some knowledge about clutch slip, you may also want to know more about clutch judder. When clutch does not engage properly, the engine will experience a kangaroo start or intermittent power to the wheels. This must be solved at once by checking your clutch release mechanism and cable.

Clutch problem is always a big deal. Once it is not solved immediately, more and more engine power will be corrupted. More and more notchy clutch (especially on the first and second gear) is surely not a good at all. Having the clutch replaced is a good idea however, you can never assure that 100% of the original’s efficiency is attained. This is because of the permanent damage to the synchromesh has been done as the first remained notchy. If you are adjusting the hydraulic clutch, you must remove the mats from the car especially if they are thick (as they can reduce the pedal travel significantly, making the clutch appear to wear out).

So how will you know that your clutch is still going great? As your clutch wears out, it will usually start slipping or sticking, and not fully engaging or disengaging. Shifting to the first and second gear often becomes harder.

Your car may eventually stall every time you try to put in gear from stationary. Fortunately, the third and fourth can work as you can limp to a garage. If your clutch has gone, you can engage the third and fourth easily without using the clutch if you just carefully match the engine speed to the gear that you select, while your car is moving. When the clutch cable stretches , same problems can occur.

If you are looking for immediate replacement, make sure that you will get the new clutch that will perfectly match your vehicle’s transmission system. Always check your manual for the specs before purchasing a replacement. Regarding the installation, make sure that it is serviced by a qualified personnel.

Bored with your doors?

Are you bored with the standard doors of your vehicle? Why stick with such doors when you have an option to convert them into more exciting design. Nonetheless, if you want to convert your doors, you have to consider several pros an cons of having them. Among the most popular door designs that I can share to you are the lambo/scissor door, gullwing door, suicide door conversions.

Kits are available for about every car as you can also find many universal fitting kits. Manufacturers usually offer fitting service but then, you might get problems with choosing the right conversion kit for your ride.

Most kits will require cutting of the interior wing. They may also involve the use of small amount of spraying so you will need to be reasonable confident once you decide to get a DIY fit. You must understand that you must also add a door conversion before you do other paint and bodywork as these may need touching up after the door conversion is fitted.

Since conversion kits are part of the coolest styling additions for vehicles today, why shouldn’t you try it now? Let’s talk about the types of kit one by one.

Scissor doors or lambo style or vertical doors are basically pulled out a little like ordinary doors. They are lifted up over the roof line like someone doing a butterfly stroke. You can find different kits that allow the door to go completely vertical while others give option to a fairly normal pull outwards to 60-75 degrees as well as swinging upwards to 90 degrees. The kits should match the weight of the door or else, it will fall down. These must also match the amount of width available in the door hinge area.

Lambo doors are sometimes hard to close from a seated position so thought has to be given to the handles. Drop handles can make it easier or you go for the very impressive electronic opening and closing lambo doors. These doors can be impractical on the rear doors because they will swing up and over obscuring the front door.

Apparently, lambo doors are advisable for front doors. If you own a sedan, then the back doors can be the suicide doors. So what are suicide doors?

They are not doors that will end your life. Suicide doors take the hinge of the other side of the door. And they are called such because they open behind you, so as to expose you fully to oncoming traffic.

Suicide doors are fairly simple, however they can make your vehicle look strange. Nonetheless, make sure that they are properly installed in place so your ride will not look weird at all.

If you don’t want the style of lambo and suicide doors, then you last option might be the gullwing doors. The hinge of these doors is placed at the top of the door and the door swings out and upward must like the wings of a bird in flight.

Gullwing doors look impressive as lambo doors, however, these door have not become popular at all. These doors require a slightly wider opening space so if you are parking side by side with other vehicles, you may not be able to open you car. This apparently tells you that gullwing doors are not for supermarket run car.

Should you want to adopt any style of these doors, make sure that proper installation is carried out. Remember that doors keep you from getting thrown out of your vehicle. so better assure that they will remain stuck tightly in place. Better yet, look for a specialist who can successfully do the task for you.

Paint your wheels


Painted wheels are always cool, aren’t they?


Since wheels can make or unmake a vehicle, you must make sure that they remain attractive whether in a closer look or from a distance. When talking about wheels, you can name several styling options and among the most effective one is painting.
Why should you paint them? Well why not! A lot of manufacturers today start to produce wheels having colour options so why not customize your own? One of the most popular designs is the black wheel having red highlighting along the inside faces.

There are lots of alloy wheel cleaning solutions that are more than any concentrated acid. You can use these solutions in stripping the dirt and grime of your wheels in preparation for paint. More radically making the wheels clean through thorough scrubbing with a firm brush is a great help in attaining attractive appeal to a vehicle. As you do this on your own wheels, make sure that even the smallest layer of lacquer or polish must be removed, or else the paint will not adhere properly.

Your wheels are exposed to lots of several detrimental elements so there is always a big possibility of having them damaged with rust. Always grab the opportunity to repair the corrosion and impact damage on the rims otherwise, they will affect the overall appeal of your vehicle. Minor damage and abrasions can be sanded out fairly easily, but deeper damage is often repaired by specialists.

You must use a quality metal primer and have it built up in a number of thin layers that aid adhesion of the paint. When the primer has dried, mask off any areas which will have second color applied to them then switch the mask to the newly applied color so that there will be an underlap once you paint on the highlight color.

Build up the paint in multiple layers. Avoid getting the paint in the inside area of the wheel, right at the contact with the tire. Some car owners paint the entire wheel and leave it to the tire fitter to insure good fit between the tire and the rim. On the other hand, some people insist that there should be no paint on this inner side of the wheel.

The color of wheels set up attitude to your vehicle. Sometimes, it even flares up emotions, to the amaze of some. Most wheels are color-coded so that they will match or contrast the car. The powder coated alloy wheels may also be painted but it is preferable to strip the wheel back to bare metal.

You might hesitate to paint your wheels because of fear in getting damage from the kerb. Nonetheless, damage is more easily repaired through little more than a touch up pen. The layer of paint can easily kept clean as the smooth finish will repel brake dust road and grime, much easier than many alloy wheels that become corroded.

Whether you are an enthusiast or an ordinary car owner, you can always bring out the best look of your vehicle through your wheels. If you don’t want to have the hub caps or wheel covers, colorful paint will always make your day. Nevertheless, make sure that proper painting is done since it can affect the so much on the appeal of your ride.

There are manufacturers that produce rims with a detachable facing edge, which can make painting a lot easier. Furthermore, they can also lessen the difficulty in removal.

Always make sure that you will plan it out well before you strike the first stroke of paint on your wheels. If you are not confident in doing the painting job yourself, then make sure that you will look for a reliable personnel who can successfully do the task for you.

Is wing really a spoiler?




NO. Spoiler and wing are two different aerodynamic features of a vehicle. Spoilers are generally closer to the body of a vehicle and it helps diffuse air. Wings, on the other hand, are mounted much higher up and create downforce that provides more aerodynamic effects. Wings almost work like an upside down air plane wing.

In the simplest form fast moving air creates pull if the other side of an object is exposed to slower moving air. If you want to test the theory, you can take 2 sheets of paper then hold them between your thumbs and little fingers, in such a way that there is a gap between the sheets of about an inch. Blow between the 2 sheets and you will notice that they pull together, which is not what you expect to happen. The fast moving air generates low pressure region in between the paper will cause them to pull together.

So as to create lift or down force, you will need air that will move faster on one side of the aerofoil than on the other creating a pull towards the fast moving air stream. We can use a simple 2 deck deflection in creating the down force required.

Deflection will have a bearing on the amount of downforce created and the larger the angle, the more downforce there will be. However, you will pay the price with an increased drag. Most wings contain a two-angled surface having a two stage deflection that force air over the wing, taking a shorter route than the air going under the spoiler.

Looking at the typical shape of a car, you will notice that air will travel further and faster over the top of the car, than it dows underneath. This will create lift then. If you open the sunroof at speed, problem with aerodynamics will be induced.

Imagine you car as a see-saw. When you press down on the rear, the front will be lifted slightly. As you fit the spoiler to the rear, the front of the car will be lifted even higher at high speeds. This will be undesirable in a front wheel drive car. And in a rear wheel drive vehicle, you will need the front wheels to steer even if traction is enhanced a degree of lift at the front is adverse.

To counter the front lift, splitters can be used. Also, front and rear skirts can be fitted to create downforce at the front of the car so that the amount of air rushing under the car is controlled. As you start redirecting the air rushing over the car, an amount of drag will be generated to rob your speed and fuel economy. There will therefore be a line between an efficient spoiler and wing design and inefficient ones.

The best wings are usually adjustable so that the driver can set his preferences to track conditions. You can find such advanced features on most sports cars today such as the Ferrari models.

Indeed, spoilers and wings are great for enhancing the aerodynamics of your car. If you want to enjoy a really smooth and seamless downforce and air redirection, then you need to have your spoilers and wings properly installed on your car. This may seem simple but if you try to figure it out, it is such a complicated task. Better yet, if you are not confident of your own skills, look for a qualified technician who can have your spoiler and wings installed successfully.

Even so, make sure that you will choose the right spoiler and wing for your ride. A lot of non-standard spoilers and wings are available in the market, so beware. If you happen to get such non-standard parts, your vehicle’s aerodynamics will be affected significantly. Remember that these aerodynamic parts must not reduce fuel economy. Be wise in selecting your new spoilers and wings then.

Is you engine balanced?




Balance matters a lot when speaking about vehicles. This is especially true with your engine, which is subjected to extreme pressure and heat during combustion. Moreover, with all the rotational speeds that induce vibrations to parts, a balanced engine is surely needed to maintain efficiency and reliability.

No engine can however be perfectly balanced because of the amount of subtle factors, though we can improve upon the balance of a mss produced engine. You can do something to maximize the power delivery of the engine, by carrying out some modifications. Nonetheless, you must not overlook the benefits of balancing the engine to sustain higher engine speeds.

If you want to attain balance in your engine, you must focus on 2 main areas. First are the components inside the engine whose weight and features needs to be assessed properly. Second are the forces created within the combustion.

Balancing engine components involves a lot of processes. One is blueprinting, which refers to the matching and machining of components as a set with a unique engine. Like a tyre installer has a special machine to balance your wheels a machine shop have a dedicated engine balancing machine onto which the components fit and rotate.

The main engine components in an engine to be considered for balance are the bearings, flywheel, piston roads, piston and rings, crank, and pins. Weight is removed from the heavier side of each component so that balance is achieved. This factor incrementally increase the imbalance so lighter components are used to get more stability in the engine, though we still have to consider that some light components are weak.

Pistons and rods are usually machined as a matching pair so the weight and dimensions of each is closely matched, making it well on the way to having balanced engine. On the other hand, the crank usually has a metal cut away and sometime weld to adjust the weight.

The crank at the bottom of your engine has a hard task, which includes conversion of the vertical motion of pistons into rotational forces. Crankshafts are forged from steel thorugh they can also be cast from iron. A machined crank from steel can be a lot stronger as the metal has not been subjected to heating and cooling cycles of casting.

After balancing the engine components, you will need to balance the dynamics. If the compression ratio is out between cylinders, there will be imbalance and vibration since the engine turns over. Such ratio can be affected by a large number of factors, hence, the cylinder wall can get damaged later on. Furthermore, weaker gaskets, poor valve seating, and bad spark plug will also come out. It is surely favorable to take compression readings from each cylinder at regular intervals and check that everything is open within an acceptable tolerance. Also check the camshaft since uneven wearing can lead to stuck open valves and imbalanced cylinders.

If each cylinder compression matches, you will need to balance the fueling. The injectors should be matched and must deliver the same amount of fuel to the cylinders. The fuel/air ratio also need to match.

Once the engine is balanced, you will hear a purr as it ticks over. You should get used of the sound of the engine exhaust note on tick over. Once you lose the regular throbbing purr, you must be alarmed about the possibility of imbalance in the engine.

The engine is indeed the most important system in your vehicle. Once perfect balance is lost, other auto systems will soon fail too. To tone down expensive repairs and replacements, make sure that you will sustain the balance in your engine system. You can do it yourself by following simple procedures that are rampantly available in the internet. If you are not so confident in doing so, you can always look for a reliable auto technician.

Blow that....

The exhaust is not just about how good your vehicle sounds. It is also about the overall performance of your ride. Furthermore, exhausts importantly deal with the management of fumes and poisonous gases. Well then, how much time would you allot for maintaining and repairing bad exhaust parts? Better think about it right now.

Getting rid of the exhaust fumes while reducing pressure is what you surely need to attain higher BHP. One way of working on this is by polishing the inside of the exhaust, which can allow fast exit of gases.

Cars with 1.6l engine, according to Torquecars.com, should be provided with a maximum of 1.5 to 2 inch pipe .While 2.5l engines should go with 2-2.5 inches then over this go with a 3 inch exhaust. The bore size applies all over the length of the exhaust up to the back box.

The back box and exit pipe can be a little wider however, it won’t give more power, instead, it will just give deeper sound. Gases will flow better from a large pipe to a small pipe. Steps will cause turbulence and this can interfere with the airflow. Later on, this will contribute on the quality of performance.

The shape of exhaust manifold can also be critical. If you think that your exhaust parts are simple auto parts, then consider the complicated calculations made by experts so that all features are proportioned and perfect for handling pressure and gases. Consider aftermarket performance exhaust headers when replacing the original.

If you still want to improve your exhaust, smoothing out the inside using grinding wheel on a drill can help. You can also get a purpose built stainless steel unit that will perfectly fit into your car.

Some of the best systems are called 4-2-1 (means that they go from 4 pipes into 2 pipes and then into 1 within 3-step process). Other standard exhausts are 4-1, where the pipes are merfed at one point lower down the manifold. A larger diameter of exhaust signifies that as the pressure needed to expel air is lower, the whole process will get quicker with a lower push needed. Cats suck power by slowing up the airflow. Nonetheless, the catalysts (which is made standard for all exhausts) can reduce efficiency.

You might have heard about the catback. High flow sports cat can give improvement on most applications. This benefit however will be minimal on smaller engined vehicles.

Most standard exhausts are cast and are composed of many imperfections on internal suface. Ridges on joints are often seen on these parts. When there is grinding inside the exhaust. Smooth airflow and more improved performance are possibly attained.

Hood temperature is one of the biggest jinxes found in your vehicle. Wrapping the exhaust manifold with a heat resistant wrap can result to a dramatic temperature reduction. It will help the cat reach operating temperature quicker. This can also ensure longer life and efficiency.

So whenever you want to blow clean exhaust, while improving the performance of your car, then start upgrading your exhaust now. Make sure that the next time you drive down the road. Your exhaust will not bring you into troubles. Also ensure that proper care and replacement are provided upon discovering exhaust problems. You can check your manufacturer’s manual if you want to know the basics in maintaining your exhaust. If not, you can surf the internet for countless options in enhancing your vehicle exhaust. When looking for high-quality replacement, demand for the best-quality one since the exhaust system always need to be precise. You can also ask for the opinions of your dad, brothers, family relatives, or experienced friends.
