Energy Suspension Rear Subframe Inserts 8.4108R

Factory rear subframe bushings are very sloppy. Scion engineered these to rely heavily on bushings to absorb bumps and cater to ride comfort. The problem with that is every time you try to launch the car, the rear bushings bind up and then snap back repeatedly making the rear subframe bounce up and down. Combine that with a stiffer suspension, coil overs or stickier rubber on an aging tC and you have bad wheel hop off the line.
