Caliper Bushing Upgrade Kit (CBMW1)

This kit will eliminate caliper twisting caused by rubber guide pin bushings. This kit, consisting of precision guide pins and machined brass guide bushings will allow your calipers to squeeze evenly on both sides of the brake rotor, just like expensive multi-piston big brake kits. This will result in much longer pad life and more consistent brake system feel. These are a must if you race your BMW. This kit is SCCA and BMW CCA Club Racing approved. This kit fits both the front or rear calipers (but sold per axle). The ideal set-up is to run both front and rear on your car. Installation is quite simple. Does not fit E30 318/325 with Girling calipers nor E24 M6/E28 M5.

*For the rear calipers only of E9X 335i and E9X M3 models*

Note: Recommended for track use only as these require regular and often lubrication.
