Modify car wheels rims and upgraded ET

A lot of friends buy a car after the first step is to change a good looking forged aluminum wheels, the reason is very obvious.

1. beauty

2. better performance of car performance

3. lighter and stronger

4. leave greater space modification and heat dissipation for the brakes

Now, let's talk about the screw structure of the forged wheels. The wheels and rmis need to be mounted on the car and needs to be installed on the hub that is extended by the brake disc. Different wheel rim manufacturers will use different hub for different kinds of cars, with 4 hole, 5 hole and 6 hole. Most of the car sports cars use 4 hole and 5 hole, while the jeep uses 6 hole. And the distance between the hole and the hole is different. Some of the more widely used, such as 4x100, 4x114.3, 5x100, 5x114.3, 5x120 and so on, are one of the necessary data on the alloy wheels. The number in front of you is the number of nails, and the number behind is the distance between the nail and the nail. For example, your car wheels is 5x114.3 wheels, so your car can only be loaded with this type of hub. The measure of distance is the right one. 4 hole and 5 hole are illustrated, and the 6 hole refer to the 4 hole.

The size and width of the car wheels rims is a very important data. The bigger the size, the thinner the tire is, because we should keep the circumference of the tire as far as possible, otherwise the speedometer will cause a deviation. The specific conversion formula in the forum has posts, the needs of friends can be searched in the forum. The thinner the tire, the more obvious it feels for the road. The wider the car wheels rims, the wider the tire can be loaded. Although it will increase fuel consumption, the larger the grounding area is, the more stable the land will be. The friends considering the performance of the vehicle should reasonably replace the wider tire.

The width of the car wheels rims is in inches, usually called the J value. The width of the car wheels is determined by the width of the hub. In order to get a wider tire, the car wheels rims must first reach a certain width.

Wheels offset this is a very special value. I'd like to make a special point here. The friends who want to modify power wheels should pay special attention to this data. Look at the side of the hub, look for the middle line, the distance between the middle line distance and the actual contact surface of the hub, is the value of the offset.

The ET value is Offset value, namely the offset, installation junction rim and center line deviation, unit mm, positive, zero, negative three!

When the ET value is 0, the contact surface of the hub and hub is located in the center line of the hub. When the ET is positive, the more the contact surface is on the inside. The smaller the ET value, the closer the circle is.

Hub is the surface of the screw (the fastening surface)

The negative offset is fixed more than hub line (close brake system).

The "bowl" type of car wheels rims is a negative offset, SUV models and part of BMW's car is a negative offset.

The zero offset is two superposed.

It is fixed on the outer surface of the wheels offset

Is the offset of the hub in common precursor and part of the drive type.

The car wheels rims are divided into 2 kinds of casting wheels and forged wheels. Casting wheels is a more primitive method, the wheel is heavier and the strength is poor. But the cost is cheap, so there are still some wheel rim manufacturers in use. Most of the forged wheels belong to the race / street, with a beautiful style, light weight, high strength, and uniform distribution.

The forged wheels is also divided into multi - layer forging and single - layer forging. The single layer is generally lighter, while the multi-layer is more durable and durable, and is used with the track.

The general multi-layer forged wheels belongs to the deepdish type, and the screws are tightened around it. There are also a lot of fake goods sold on the market, looking like a multi-layer forging, in fact a false screw on it. Just turn over to see whether the reverse side is stratified or not.

When buying car rims, we should pattention to the wheel axle. Because the shape and size of the different axle parts are different, there are some small holes in the middle of the hub, which can not be installed. In the case of such a situation, finding a gasket can also be solved.

Finally, let's talk about the taboos of modifying wheel.

Not use too big size car wheels rims. For example, a lot of people think that as long as the wheel installed does not touch the outer sheet metal OK, actually remove the wheel carefully look at the inside of the structure, there are many places are very easy to card, especially after the shock will open up the car bumps in the road instantaneous compression. So modify big size wheel, also should be properly used, and can not taste the beauty of the last car can not open. In addition, the car wheels width should also be noted.

And the brake caliper stuck to the car rim. Since the car is now used for safety problems, the large number of brake calipers are often used, and the 4pot calipers are much larger than the singlepot. In this case, the offset is not enough and the design is not suitable for the wheel, and it is often easily stuck to the brake calipers. Fortunately, it is easy to find that once the wheel has the sound of friction, change it quickly.

The car tire width. If you run a run, you should carefully observe the wear and tear of the inner and outer sides of the tire, and the wide tires are easily stuck to some parts.
