Improve Handling, Reduce Noise, Eliminate Vibration
Stiff Ring made of special formula alloy aluminium. It used to correct the car body basic geometry by filling the gap between the sub frame bolts, sub frame and the car body bolt hole. Car engine, transmission, suspension and the body shelf are mounted on the sub frame. Thus, correcting the geometry setup with Stiff Ring, the car handling will be improved significantly. By eliminating this free gap, vibration to the car chassis & undercarriage will greatly reduce. This helps to protect & prolong the car undercarriage parts life span. Eg: Steering rack, lower arm and etc.
