BIG-BRAKE BRACKET KIT, FRONT, GMSS

The KORE3 Big-Brake Front Caliper Bracket Kit for the GM short-spindle application adapts high-performance, high-quality, 5th or 6th generation Corvette (C5/C6) brake components to your GM short-spindle equipped car. Please refer to the KORE3 Big-Brake Application Chart for details regarding specific vehicle compatibility.

Notes:
  1. KORE3 GM Short-Spindle kit is designed for forged short-spindles only, of which there are three (3) variations as described below. GM made a fourth short-spindle design that is not compatible with this kit. The spindle is cast, not forged, and can be readily identified by the integral cast caliper mounts and steering arms. We currently do not offer a kit for this spindle application, however it can be swapped to the forged GM short-spindle or converted to the GM tall-spindle if you are interested in adapting KORE big-brakes to your car.


  2. Kit is 100% bolt-on. No welding, cutting, or grinding necessary if KORE3 components are used.


  3. Minimum �17" wheels are required for caliper to wheel clearance. Not all �17" wheels will fit. Please verify fitment prior to ordering using the appropriate KORE3 fitment template. Wheel fitment is the buyer's responsibilty. Please contact us if you have any questions regarding your specific application or the proper use of the templates.
