The optimal thickness of the flange is between 25 and 30mm, the flange will increase the coaxial wheelbase of the car, the driving ability to grip the ground will become stronger, thus greatly improving the stability of the car in sharp turns, not easy to slip phenomenon, so that the safety of the car can be improved. Vehicles in the addition of flange, will make the car tire rim and wing plate flush, the car will look more dynamic, the visual effect will be better. Adding flange can balance the center of gravity of the body, so that the car is more stable when driving, mostly used to prevent the vehicle from skidding when turning sharply, causing danger.

Adding a flange is not recommended for non-players. The safety hazard is that once the flange screws are loosened and broken, it will cause the wheel to fall off. The probability is very low, and the screws are loose after the old driver can feel the wheel swinging, timely parking can avoid accidents. But the addition of poor quality flange is more harmful, for example, the screws did not break loose, but the flange because of the lack of strength and rupture! At this time the wheels are sure to fly out, the vehicle is in danger of losing control.

Automobile modification in the most mentioned is to add flange, add flange can not only make the vehicle appearance looks more full, and for vehicle stability is also greatly improved.

The purpose of adding flanges is to increase the wheelbase of the car, or to replace your favorite wheels by adapting flanges. The biggest benefit of increasing the wheelbase of a car is the increased stability and better handling. It can solve the problem of sideways drift brought about by high-speed driving and cornering, and the car runs more smoothly, and the comfort is also improved.

The principle of flange modification is very simple, flange is a thickened spacer, can be understood as a pad between the wheel hub and brake drum. In this way the tire is moved outward by a distance of the thickness of the spacer, and the wheelbase is naturally increased!

There are currently two types of flanges used for modifications. One type requires the use of extension screws, and the flange acts as the equivalent of a spacer. This kind of flange requires high screw strength. The other kind is the flange with adapter screws, the flange is mounted on the brake drum through the screws, and then the self-contained screws can replace the brake drum screws to fix the wheel.

There are also disadvantages to fitting a flange. For example, there is a certain amount of safety hazards, and secondly, the flange increases the unsprung mass of the car, and the suspension reaction speed has been imaged. After adding the flange, the wheel pivot point moves outward, the suspension bearing force increases, which may affect the service life of the suspension.

The advantage of adding a flange is more stable when turning sharp corners, the following is the content of the advantages and disadvantages of adding a flange:

1.Car plus flange advantages:

(1) some models of the body posture is poor, plus flange after the wheel slightly convex, from the appearance of the vehicle can make more sense of power, do a wide-body modified car will appear to be a tire concave, plus flange can perfectly solve this problem.

(2)After installing the flange, the vehicle coaxial wheelbase becomes longer, and the vehicle can improve the feeling of floating and tilting when driving at high speed and turning sharply.

(3)The flange material is usually aluminum alloy, which will not increase the weight too much.

(4) Modification of large brake calipers retrofit flange can give the caliper position.

2.Car retrofitting flange disadvantages:

(1) go uneven road when the vehicle bumps will be more serious, for half-axle universal joints have some damage.

(2) The quality of the flange is uneven, once the flange is damaged, it will also affect the original wheel hub.

(3) vehicle suspension tuning one of the factors is to reduce the abnormal wear of tires, retrofitting flange to change the wheelbase, so that the tires will appear abnormal wear.

(4) The vehicle should not be heavily loaded, the reason is exactly the third point mentioned will lead to abnormal tire wear, sometimes rubbing the wheel brow.

As we all know, the purpose of adapter flanges is to increase the wheelbase of the car or to replace the favorite wheels with adapter flanges. The biggest benefit of increasing the wheelbase of a car is increased stability and better handling, it solves the problem of sideways drifting and other things that occur when the vehicle is traveling at high speeds and cornering, making the vehicle run smoother and with improved comfort.

Flanges are usually used to increase the width of the car and widen the track width even if the wheels protrude which will make the car more three dimensional and dominant. It is said to improve the stability of the car while cornering and reduce the swaying of the car, making it very popular among modified car enthusiasts. However, if a family car wants to modify this thing, it's best to know the following points first!

Actually, after reinstalling the flange, the tires may push against the blade plate; because the flange is mounted between the brake disc and the wheel hub. As a result, when the flange is installed, the tires will protrude outward by a few centimeters, and the suspension compresses the tires upward as the car passes over speed bumps or rough road surfaces. In addition, the suspension of a family car is already soft.

Therefore the suspension is compressed too much and the protruding tire will be easily pushed against the blade plate. First, the vane plate is deformed by the top of the tire, and then the tire blows out. Of course, if your car's suspension is stiff enough, you don't have to worry about this. The wear on the wheel bearings will accelerate after the flange is reinstalled; at the outset, family cars were designed for economy and comfort.

Replacing wheel bearings is a hassle, so if the flange must be refitted, the mental construction of the axle head and bearing damage must be done well in advance. There are two types of flanges available for retrofitting, one is the use of extended screws, where the flange functions as a spacer, this requires a strong screw. The other is a flange with adapter screws, which is mounted on the brake drum by screws, and the self-contained screws can be used instead of the brake drum screws to fix the hub.

And after reinstalling the flange press, the steering may leak oil; because after reinstalling the flange, the wheel bulges out, and then, the distance between the tire and the steering ball joint on the steering knuckle becomes larger. However, the distance between the steering ball joint and the steering remains the same, in which case the steering force arm is shorter than before the modification.

The steering then requires more force to push the tires to turn, which equals more work for the steering. In addition, many owners are unaware of regular steering maintenance, so in the long run, it only accelerates the damage to the steering, which ultimately leads to steering leaks, and almost all repair stores and 4S stores will not repair the steering.

Partly because it really can't be fixed, but more so because it takes time and effort and doesn't make money. Therefore, once the steering fails, you can basically just replace it. The cost of replacing a steering gear in an average family car is about $5,000, and when you think about whether it's true that you get more than you pay for, it's important to buy a major brand and a specialized vehicle when reinstalling the flange.

However, installing an inferior flange can be harmful. For example, the screws do not loosen and break, but the flange breaks due to lack of strength! At this point, the wheels are sure to fly out and the vehicle is in danger of going out of control. Where the culture of car tuning is thriving, it is very mature, however, the culture of car tuning in our country is still in its infancy, and in order to make money, many small workshops sell forged flanges using casting technology.

As a result, there will be a tragedy that the flange of the car breaks and the tire comes off while driving! However, major foreign tuning manufacturers are engaged in the manufacture of flanges and have sophisticated testing methods and quality standards. Even according to the model of the wheel, special flanges are manufactured for special vehicles, and only such a modification can guarantee the performance and safety of the vehicle!

Finally, do not save money on flange attachments. That said, tire bolts and nuts are just as important as flanges! If you use wider tires and the original fenders are insufficient, the tires may contact and rub against the fenders during steering, affecting driving safety. At this point, padded flanges can be added to allow the front wheels to move outward without contacting the fenders. At the same time, the stability of the car can be improved due to the widening of the left and right wheelbase.

The front wheels are restricted from moving from side to side during front steering. If damping is reduced, the wider hubs tend to rub against the wheel arches during compression, and if the flange is too thick, the axle will be subjected to more force, so it is recommended that a thinner flange be used. In fact, with the flange filled, control can be improved to avoid scratching the wheel arch and hub.

Summary: Personally, I still don't recommend flange modification if the braking system is not improved. The new discs and calipers of the improved braking system are lighter than the original. At this point, adding flanges to increase the clearance between the hub and caliper, the improved large caliper will not rub against the hub. Also, the weight of the installed flange will not add unsprung mass, and the flange cannot be of poor quality and have strength specifications.
