KSB750 is designed to lock the rear subframe which allows for more precise alignment of the rear wheels & limits the amount of rear subframe movement under cornering loads which can result in poor dynamic alignment settings. The hardware can easily be installed & removed between motorsport activities. The kit will increase rear NVH as it effectively locks out the rear subframe bushings. It is designed for motorsport use only & should not be used for extended periods as it may lead to premature chassis wear.
