Set of 8 Aluminum Steering Rack Bushings for all year model 928's. Ideal for track cars where vibration transmission is not a factor. You can check them by raising the front of the car and seeing if there's play in the wheel. Have someone hold the steering wheel so that you're not turning the steering wheel. If you feel play in the wheel then repeat while watching the end of the steering rack. If the rack moves, it's probably the bushings.
