Our exclusive street performance bushings and mounts are made with a more forgiving urethane formula! During spirited driving, polyurethane bushings and mounts provide more responsive handling and maintain better control over suspension geometry than stock bushings. Along with this improvement in handling, though, comes a stiffer ride -- a welcome side-effect on a smooth race track, but much more noticeable on the streets. Our street performance urethane is formulated with a touch of polyester. This new compound is more forgiving than 100% urethane, so it’s better for street BMWs. Performance Tuned Front Control Arm Bushing - Offset For More Caster - Sold Individually Retail price is $99.90 + Shipping For M/A Members, I will take $65.00 if you pay by "Personal" on PayPal.
