Just like some sports cars sold in the mass market, there are so-called LSD like the sub-products of gearbox gaskets. The principle is to make the power transmission more direct and fast.
The most frequently asked question is regarding its function; in simple terms, the tolerances retained by the original factory will cause the power transmission into the slewing force when the vehicle is stressed, so that the shock absorber cannot absorb all the impact forces at one time. It is easy to cause a double bounce and a slow road feeling feedback. When the tolerance is filled, the problem can be significantly reduced, avoiding the inconspicuous feeling on the road and the bounce of the shock absorber, making the car more solid.
