Mistake one: the lighter the better, with the weight theory hero, the refitting world is widely spread: under the spring 1 kg is equal to 10 kg on the spring has already been deeply popular, so many hub refitting users in the choice of hub, the weight of the hub as the evaluation standard, excessive pursuit of hub lightweight.

　　Because the hub produced by the regular manufacturer needs to pass three strict performance tests: 1) impact test, 2) bending fatigue test, 3) radial fatigue test. It can be seen that it is difficult to pass three performance tests if the hub does not have a point "weight". It is the crown road to reduce the weight of hub as much as possible on the basis of satisfying the strength!

　　Error two: the bigger the hub size, the better, the greater the United States.

　　Many people refit the hub original intention is actually simple and rough: good-looking! The hub size has become larger, the vehicle effect looks fuller and powerful. Say straight, make it higher! However, blind increase of hub size, light with calipers, gear plates, shock proof "close contact", heavy damage to the vehicle suspension system and increase unnecessary fuel consumption.

　　Generally, conventional hub modification is better to upgrade 2 inches, and also pay attention to the matching with tire specifications. The outer diameter of the tire is changed < 3. Otherwise, it will affect the accuracy of code table. If you don't care, you may receive many tickets for no reason, and you will be forced.

　　Third, take wheel with "appearance", ignore wheel hub parameters.

　　The change of hub style improves the appearance effect of the whole vehicle. But if only attention to the appearance of the hub is not paid attention to the matching of the wheel hub parameters with the original vehicle data, it is easy to replace the hub and fender, caliper, scratch and even can not be loaded at all.

　　Mistake 4: ignore the wheel hub modification link, the hub is not installed correctly

　　Many friends who have changed the hub at first, they are very excited to drive to the store and install them immediately. I hope the moon will arrive. Hub a quick look, on the installation of the small brother said: install! Pack! Pack! Because of the variety of the refitting shop, if the following installation details are not paid attention to, the hub installation would be a moth.

　　1) No reducer is installed: there may be jitter problems when the vehicle is driving in daily operation.

　　2) Dynamic balance weight is not reset to zero: when the vehicle is running at high speed, it may shake.

　　3) Hub not tightened by torque plate hand: loose hub may be in danger of falling off, too tight may damage nut / bolt.

　　4) The tire specification does not match the hub: the tire is worn abnormally, even the hub cannot be installed or there is a scratch problem.
