Whiteline Rear Subframe bushings replace the stock soft rubber units with harder polyurethane units. These Harder bushings eliminate all the rear sub frame movement during hard lateral loads, helping reduce the typical subaru snap over steer, and providing more crisp feed back out of the back end of the car.

By reducing the shifting of the rear subframe, the back of the car will break loose much more predictably. Unlike the stock bushings that snap back when they are unloaded. All these things make the car much more enjoyable, and predictable to drive.
