POLY REAR TRAILING ARM BUSHINGS
If you're looking to tighten up the rear suspension of your E30/Z3 this is it. We have used and tested all different types of bushings over the years, and found the Revshift poly bushings to be the best on the market.
Comes with Teflon lubricate. Will not squeak like other cheaper poly bushings.
Fitment: E30, E21, E36 318ti, Z3
80A black: Slightly stiffer and stronger than OEM rubber. No additional NVH. Great choice as an upgraded stock replacement (OEM+).
95A green: Significantly stiffer and stronger than OEM rubber. Minor increase in NVH. Excellent for enthusiastically driven street cars and track cars.
70D white: Drastically stiffer and stronger than OEM rubber. Moderate increase in NVH. Most commonly used on dedicated track cars.
