NOTE ON THE DIFFERENCES OF POLY AND DELRIN/SOLID IN THIS APPLICATION
We offer the Garagistic E36 differential bushing kit in 3 different materials: 80A poly, 95A poly, and solid Delrin. 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 are for the ultimate in performance. It is designed for the truly hardcore racers and track enthusiasts.
