Upgrade the rear suspension precision of your BMW with 90SH polyurethane rear trailing arm bushings.
These bushings replace the soft factory rubber components that allow unwanted movement under acceleration, braking, and cornering. The 90SH polyurethane compound delivers a firmer, more controlled suspension response while maintaining acceptable comfort for street or mixed-use cars.
Ideal for spirited driving, track days, drift setups, or performance street builds, these bushings help stabilize rear toe changes and improve overall chassis balance.
