Performance Gains / Why It’s Needed

OEM rubber bushes allow rear control arms to flex, causing dynamic camber and toe changes during hard cornering. This reduces rear traction and can make the rear feel unstable. Solid bushes eliminate flex, keeping camber and toe consistent, improving grip, stability, and driver confidence during aggressive driving or track sessions.
