Whiteline Rear Differential Support Lock Bushings Kit Subaru 2002-2007 WRX / 2004-2007 STI
KSB751 will reduce rear-end float particularly under acceleration. It will also remove drive train slap on hard gear changes while delivering more precise handling and chassis response from the rear. Highly recommended for big power engines and competition work including drag and circuit racing. Note: Will induce NVH.
