Modified car dictionaries: hard plastic with metal bush bush

In the car there is a suspension system called "submissive degree" as used herein, Billet Steel Crankshaft the degree of influence is generally supple suspension system of elastic elements such as springs, suspension bushings and the like. As the elastic member, they must have the characteristics of a deformable, thereby absorb road shock, protect other systems of the body, this way, supple degree of comfort on the closely. In general, the partial suspension soft sense to create a more comfortable ride, hard, and vice versa. But the most obvious problem is generated supple suspension, the suspension lateral deformation becomes large when the vehicle turns, the wheels of the impact point, especially the rear, not easy to use the steering wheel to be amended.
    To this end, modified car manufacturers have come up with a relatively hard liner to replace the original soft liner (also gum), to limit the lateral movement of the suspension, and finally to have a vehicle in a curve in the ideal point of this point Accuracy can play with the steering wheel while driving to the test, with a hard liner to steering wheel input vehicles reflect rapid, positive, but this test is more of a sensory experience for the driver's skills, experience has certain requirements, crank positive high and low degree, mixed reviews. In addition, as mentioned above, instead of hard-turning ride comfort liner will have an impact, but also time-consuming modification bush a lot, these are the first to know about before conversion.
 There is also a modified car full metal liner, some people will call them "marbles", which with the shape they have a certain relationship. Compared gum bush, a low degree of deformation of the metal liner can be considered rigid, limiting the extent of lateral movement of the suspension to be significantly higher than the former, so that the front point to more accurate, so it is widely used regular motorsport. But metal bushing affect significantly affect ride comfort, crankshaft and relatively short life, is rare in the streets modified car.
