Heavy-Duty Thrust Rod Bushings

The E28 chassis and front end shimmy go hand in hand, especially with the addition of larger wheel and tire packages. This shimmy mimics warped rotors, and is most noticeable under light braking from highway speeds. The most common cause we see in our shop are the weak factory thrust rod bushings. These bushings are mounted at the rear of the strut rod, a diagonal link which helps prevent fore and aft wheel movement. Our hard rubber bushings address this problem as well as improving steering feel and "turn in". Sold in pairs.

All E28 P/N 3111567

Remember to check the condition of the entire front suspension as well as wheel balance/tire roundness and rotor run out/thickness when trying to diagnose a shimmy.

Aluminum Front Lower Control Arms

Stronger than the original cast steel arms and about half the weight. Reduction in unsprung weight improves handling.
