If you're looking to tighten up the font suspension of your BMW 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. Offset control arm bushings came stock on the E30 M3 and 1995 M3. Non-M3 E30's and E36's benefit from these bushings because they increase the caster and improve the vehicle's handling and stability. Comes with Teflon lubricate. Will not squeak like other cheaper poly bushings. Hardness80A 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 TEAL: Drastically stiffer and stronger than OEM rubber. Moderate increase in NVH. Most commonly used on dedicated track cars.(NVH = noise, vibration, harmonics)
