StopTech Replacement 309x32mm C43 CBK Slotted AeroRotor Ring w/Race HW (Left & Right Side) 31.H3B.0E71.87 + 31.H3B.0E72.87

***RIGHT SIDE ROTORS ARE MACHINED WITH STRAIGHT SLOTS AND LEFT SIDE ARE CROSS SLOT*** Stoptech made a mistake when machining and we have no way to exchange these. The rotors are both the correct castings, vane count, part numbers BUT they were machined with two different slot patterns.

Replacement 309x32mm slotted (left) Race brake rotor for StopTech C43 CBK brake kits.

This is the Race version - with conical washers good for an additional 2mm of float from sport hardware.

One of the advantages of a true motorsport brake kit is the ability to change out the common wear items - rotor rings, pads, and caliper seals. Other brake kits look like 2-piece rotors but are not serviceable, driving up replacement costs. With replacement Stoptech rotors, simply transfer the rotor hat from your old disc to the new disc (rotor hardware included).

**Rotor hat and caliper in picture are not included**
