Car performance body kits are now a days being manufactured by different materials. All have some advantages and disadvantages and selecting a body kit of a particular material depends totally on the price, conditions, usage and other various factors. The different materials could be polyurethane, fiber glass, carbon fiber, ABS plastic e.t.c.

In this post I intend to discuss the advantages and disadvantages of car body kits made up of polyurethane. I hope this will make your mind even more clear and lead you to a better decision making when selecting the performance body kit for your next exterior car modification.

Advantages:

The biggest advantage of attempting your car body kit modification and then replacing it with polyurethane is its durability. These are more long lasting than the famous fiber glass body kits as the material is more flexible. This flexibility makes it to get mount on your car very easily. So if you are reluctant in changing your car's body kit and consider installing a new one very tough job then polyurethane body kits will change your opinion once and for all. This attribute makes a car modification quite simple and pretty much a DIY job hence saving time and money.

Since polyurethane is a hard and flexible substance, it does not damage easily as compared to its other competitors. So you need to bang real hard your car in order to place an impact on the kit. But wait. Did I say "Bang Real Hard!!!" you definitely would not love to strike your car anywhere no matter what material your car body is and this feeling become even more extreme when the material is polyurethane. Because the moment your car strikes and an impact is laid on the kit, there's a great disadvantage waiting for you which I will discuss in the disadvantages section.


Disadvantages:

Since it is a high quality material so generally the polyurethane body kits are more costly than other materials so you really need to have tight pockets if you are going for it. This is a great drawback as it goes out of reach for many car enthusiasts and they cannot afford it at all. Secondly, painting over polyurethane is not a convenient job at all at paint requires more adhesion and also sags more quickly over time when exposed to sun or heat.

Furthermore, these are more heavy than fiber glass, so when you mount them over your car keep your mind well prepared for more fuel consumption as more power is going to be required by your car to drag it. Now coming to the disadvantage because of which you would not love to hit your car and cause an impression on it. Polyurethane body kits are not easily repairable or in some cases, it is impossible do retain the original shape of it and you will only have to replace it with new one as the car dents are not going to be removed. So you have to be even more careful on the road.

Bringing my discussion to an end, polyurethane sure is an expensive material to afford but think of it from the positive angle. The less the people will have them, the more your car is going to be unique. The decision is sure in your hands.

Ever wonder why there are different patterns on the car tire? Are these designs or patterns only to quench our aesthetic thirst or do they have some stability purpose too? Definitely these tire tread patterns play a great role in car's stability and tire traction while driving at different terrain. Not one type of tire tread pattern is suggested for all types of roads in all weather conditions. Some are best for wet conditions, some for winters and some for summers. Similarly different tires are advised when driving for different purposes. Drag racing tires or street racing tires are different for driving on a smooth track or for domestic purposes. You use a non compatible tread pattern and the tire traction will be lost which may result in severe results.

Below I will discuss some types of tread patterns you may find on different tires along with their appropriate use and their good and bad points. You may find following patterns on a normal tire.

1). Asymmetric Tread Pattern
The tread pattern differs from both sides of the tire. It also means that a tire features two patterns along its whole circumference.With this type of pattern, the manufacturers ensure that majority of the possible terrains are dealt with a single set of tires so the drivers do not need to change their tires in different conditions.

Since the tire with this type of pattern provides a higher contact area, it is considered good for high speed cornering. More than one type of tread pattern means that the inboard and outboard halves have two sizes of groove blocks. The grooves on the inward halve (smaller blocks) help retain tire traction on wet surface while the larger blocks on outward halve, helps great in cornering.

Because of these features they are proposed for high performance and motor sports needs. However you need to position them right way around to make them perform well.

2). Symmetric Tread Pattern
As the name suggest, the there is a single tread pattern on the entire tire. Therefore the inboard and outboard halves represent the same patterns. Hence the name, Symmetrical. Tires with such tread patterns emit high noise than other tires. They allow using multiple tire rotation patterns.


3). Directional Tread Pattern
A.K.A unidirectional tread, the whole pattern along with lateral grooves, roll around in one direction along the entire tire's circumference. These lateral grooves allow water to eject more efficiently (hydroplaning) hence prevents the car to skit on wet surface. These are also considered effective as street racing tires however there is one disadvantage of them.

When rotating tires with unidirectional treads, the tire on the front axle should be shifted to the rear axle, and vice verca. If different tire sizes are used on the front vs. rear axle, the tires become location-specific and prohibit tire rotation unless remounted.

4). Asymmetric And Directional Tread Pattern
These have V-shaped lateral grooves on them. Hence they are also known as V groove tires.They are much near to directional tread pattern tires hence they should be treated like them. Disadvantage is as same as directional pattern tread pattern tires.

In the last article we talked about Safety Mods. Now it would be appropriate to have a look at some legal issues arising due to car modification. For this purpose I would present an extract from a website which deals with and educates on the legal implications due to car modification. But before that I would like to have some words with you.

Laws enacted by law enforcing agencies are for the betterment of oneself so you must not take steps to violate these laws as it could prove lethal to you as well as civilian around you in long or short run. Now lets see what legal problems you can get into because of unlawful car modification.


Under traffic laws in most states, drivers may be given a traffic ticket for operating a vehicle that has been modified in violation of laws that regulate vehicle specifications and vehicle equipment. Examples of vehicle modifications that may result in a traffic ticket include:

* Addition of non-standard lighting (neon lights, under-vehicle lights),
* Alteration or removal of air pollution and emissions control device
* Modification of vehicle ground clearance ("lowered" or "raised" vehicles),
* Removal of mufflers and other sound-control devices, and
* Window tinting (especially tinting of windshield or driver/front passenger side windows).

An unlawfully-modified vehicle can receive a traffic ticket for a mechanical violation. In some states, citations for certain unlawful vehicle modifications are considered "fix-it" tickets or "correctable violations." In California, for example, if you are given a "fix-it" ticket by a police officer, "yes" will be checked next to "Correctable Violation", and after the problem is fixed (i.e. you remove illegal under-car lights), you must get the signature of an authorized person (i.e. a local law enforcement officer) on the "Certificate of Correction" portion of the ticket. If you are issued a "fix-it" ticket for an unlawful vehicle modification in your state, read the ticket to determine whether you can mail the proof of correction, rather than taking it to court.

If the court accepts your correction, the case will be dismissed. But, if you fail to fix the problem within a short time after you receive a "fix-it" ticket, you will need to pay the fine for the unlawful vehicle modification, and you may be issued another ticket which will go on your record.

Car modification has been a recreational activity since the day first car was bought and with the passage of time, it has gained so much popularity that it has taken form of a separate industry where the car manufacturers are busy in creating high performance after market car parts. Now car modification is more popular among youth and teenagers. They are busy and regularly come up with new stunning ideas which leave us with our mouth wide open. Due to the over zealous state of mind of the youth and "Living On The Edge" nature of the art of car modification, people often compromise their safety and do not even refrain in challenging the legal authorities and violating and confronting the enacted laws pertaining to car modification.

Modifying cars can sure be regarded as an artistic activity which involves and requires great amount of creativity but putting your lives in danger and acting as a menace on the roads is not wise at all. We would discuss some safety mods and legal issues abiding by which will definitely make you a safe and sound citizen.

Car Safety Mods

When you modify and try to pimp your ride, many of them are performed to enhance the appearance and make it more presentable. But many car enthusiasts perform it to enhance the performance and efficiency of their cars. Obviously, enhancement of car's performance means more speed and definitely more risks attached to it. By applying the following safeguards, the performance enhancements is sure going to be safe.

Car Seat Belts:

Car seat belts are for you safety so when you modify the interior of the car its possible that you amend some of the settings which can possibly affect the performance of the seat belts. Make sure that seat belts are more efficient and the locking mechanisms are working properly. Make sure that whenever you wear the belt, the tension in it is intact or seat belts are of no use.


Installing Roll Cage:

Installing roll cage kits is sure a wise move especially when you are looking for some drags and drifts and street racing. Installing roll cage kits will ensure to a great extent in case of any misfortune occurs. You install these roll cage kits for better structural rigidity which acts as a supporting beam and are very protective in case of a crash. So ensure that the supplier of the roll cage kits are dependable and trusted.


Unexpected Fire Cases:

Unexpected fire cases often occur during high street end racing. When you are spending thousands on car modification we would advise you to at least have a hand held fire extinguisher at your disposal for your safety so fire suspension much easier.


Improve Car Braking:

In case when the tires, wheel rims and car body kit is modified, it sure leaves an impact on the car braking as the weight of the car is altered eventually. Make sure that your car braking mechanism is safe, sound, efficient and spot on as ever. Aligning the your car brakes to the safety rules is not an expensive job. Just make sure you have a good lock at your car brakes cooling mechanism and confirm that the brake pads cool quickly. Furthermore, just have a good look at brake shoes (pads), brake fluids, drilled disks e.t.c.


Implications Of Tire Change:

Tire change improves your car handling and ground clearance but in some cases they work otherwise. So ensure that you pay some considerations towards this aspect and replace your tires with the compatible ones which enhances the road grip and are also effective on wet tracks. Using tires specific for racing purposes and also keep an eye on the optimum pressure of your tires to ensure better road grip, traction and ultimately, safety.

Dents on a car are hated all around the world by the car owners as they seem to sabotage the whole look of your shiny, pimped out, modified car. Many car lovers, rush to their their nearest car body repair shop to fix a car dent as soon as they get one and empty their pockets by paying heavy bills of these body repair shops. Not all the car enthusiasts know that they can easily remove car dents simply by using common house hold dent pulling tools as well as some specialized tools and the cost of removing them is pretty nominal as compared to those heavy bills of body repair shops. In this post I will discuss some easy "how to remove dents" techniques which can be performed via the help of some specialized or common tools which are available every where at economical price. Its so easy to remove car dents that after reading this post you will say for yourself that "car dent fix" is definitely a DIY job.

I will discuss a some general steps of removing car dents. But first just a quick peek of some tools that are considered effective as auto dent puller.

Dent Pulling Tools:

Now there are different dent pullers or dent removers which are used to remove dents from the car. Some of these are specialized for this purpose while some of them are common house hold tools which cab also be used for this purpose. These tools or materials can be:

1. Wooden block and a hammer.
2. Suction cup dent puller integrated with air compressor.
3. Dry Ice.
4. Plunger

and many other tools which I will discuss later, can be used as dent pullers or dent removers.



How To Remove Minor Dents On A Car:

Note that these steps are recommended only for minor dents on a car.

1. First clean the area with water and a piece of cloth so you are in a clear contact with the surface area and the dented region can be easily seen.
2. Drill a hole right at the center of the dent.
3. Insert the dent pulling tool inside the hole.
4. Try to pull the dent puller towards you until it pops out.
5. Once the dent pops out, remove the dent puller.
6. If the dent has been removed, fill the hole with the body filler and cover the area with touch up paint.

Remove Car Dents By Suction Cup Dent Puller:

Most non violent way of popping out minor car dents is using a dent puller which when combines with air compressor attempts to pull it by creating a suction. Therefore I would call it as a suction dent puller. Following are the steps to use this tool effectively.

1. Clean the area with water and a piece of cloth.
2. Combine the dent puller ( suction dent puller) with an air compressor and activate it.
3. keep the dent puller on the area of the dent.
4. Make sure that there is no gap or space left open between the dent puller and the dent area of the car. As any space left opened will make it impossible for creating a vacuum and no suction would be created.
5. Once the dent puller is nicely placed it will attach to the car's metal where it has been placed. This will testify that the tool is working effectively.
6. Pull the tool towards yourself. Since there's a vacuum between the car body and the dent puller so the car dent will also tend to pop out with the dent puller.
7. That's it. You are done. De-activate the air compressor, remove the dent puller and ta-daa!!! The minor dent on your car is a history.

How To Remove Relatively Larger Dent From A Car:

If the dent is relatively larger to pull it from a dent puller you can use a small sledge hammer and a small 2"x 4" wooden block. Follow these steps.

1. Remove the upper layer of the dented area from inside the car. For instance if you want to remove dent of a car door. Reach inside your car and remove the clothing or leather layer from inside your car so that you reach the effected region from inside.
2. The area must be popping out from the interior side as it must be appearing as popped in from outside.
3. Take a wooden block and keep it on the surface area of the dent area.
4. Now take a hammer and hit the block with the hammer. Make sure that you hit the block gently or you will cause a permanent damage to the car body.
5. Your job is done once the dents pops out from exterior and the body returns to it original position.
