The additional stiffness that the poly or Delrin E36 rear subframe bushings provide means that your subframe will stay in its intended location resulting in a more predictable, and planted E36. These bushings are an absolute must for E36 cars that see constant track use. These bushings provide an overall improvement during on/off throttle loading, cornering, weight transfer, etc.

NOTE ON THE DIFFERENCES OF POLY AND DELRIN IN THIS APPLICATION

We offer the BMW E36 Rear subframe bushings 3 different materials: 80A poly, 95A poly, solid Delrin, and Aluminum. Each material has its intended application and benefits. The 80A poly is the happy medium between upgraded bushings and plush OEM rubber. It is intended for the spirited street driver, and occasional Auto-X and track use. It offers a definite increase in performance with a limited increase in noise transfer and harshness. The 95A is the next tier up on the poly scale, offering a stiffer material than 80A and increased performance to match. If you have a car with a louder exhaust and or a car intended for only weekend use in the canyons or on Auto-X and track circuit this is the bushing for you. Finally, the solid Delrin and Aluminum bushings are for the ultimate in performance. These stiff solid bushing offers almost no deflection, keeping the rear end as tight as you can get it! It is designed for the truly hardcore racers and track enthusiasts.
