The first part of the suspension system that will start to wear out and effect your ride would be the shocks and that is why we have some great performance Scion tC shocks. Replacing the stock Scion tC shocks will benefit the handling feel and performance level even when changing from a good condition factory set of shock absorbers. These new performance Scion tC shocks will cause the vehicle to settle out and recover stability much quicker after bumps and quick turns that cause the center of gravity to shift and move.
