Product details
KSB750 is designed to lock the rear subframe which allows for more precise alignment of the rear wheels and limits the amount of rear subframe movement under cornering loads which can result in poor dynamic alignment settings. The hardware can easily be installed and 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 and should not be used for extended periods as it may lead to premature chassis wear. Whiteline Subframe - lock kit. Subframe - Lock Kit
