There are four subframe bushings that connect the subframe to the E36 chassis. These are the base for all of the rear suspension! These solid Delrin subframe bushings are the ultimate performance upgrade and are best suited for race cars where comfort is not a major concern. These bushings provide a significant improvement over the factory rubber units but fit just like OEM. What this does is ensure a tight fit and reduce the amount of flex experienced by the rear subframe and allow better power transfer and more consistent handling.
The additional stiffness that the 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 a significant overall improvement during on/off throttle loading, cornering, weight transfer, etc.
These subframe bushings replace OEM part numbers - 33319059301, 33319066671
Aluminum and Delrin subframe bushings require to be pressed in. Due to the high tolerance required of Aluminum and Delrin bushings, hammering will cause damage. Professional instillation is highly recommended.
We offer the BMW E36 Rear subframe bushings in 4 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 bushings and aluminum bushings are for those looking for the ultimate in performance. These stiff solid bushing offers almost no deflection, keeping the rear end as tight as you can get it! Delrin is designed for the truly hardcore racers and track enthusiasts, while the Aluminum bushings are simply an even more long-lasting version designed for competitive cars that compete in events that Delrin subframe bushings fail tech inspection (example: Formula Drift).
