Whiteline Subaru WRX/STi 11-12 Rear Subframe Mount Inserts

Not your typical remove and replace bushing kit but simple installation means great for the DIYer's. Designed to work with the original bushing and eliminate over compliance or better known in motorsport as 'lost motion' of the rear crossmember. This Whiteline kit dramatically reduces rear cross member misalignment and movement which allows a more positive feel from the rear end during cornering.
