Performance Gains / Why It’s Needed

Stock rubber bushes flex under cornering loads, altering camber and toe angles. This can cause inconsistent grip, reduced traction, and a rear end that “scrabbles” at high speeds. Solid rear control arm bushes maintain geometry, delivering predictable handling, increased cornering grip, and a stronger connection to the rear axle, making both spirited road driving and track sessions more controlled.
