KORE3 Industries LLC: On and Off-Road Performance Automotive Components

The KORE3 ø325mm C5/C6 Front Big-Brake Kit for the GM short-spindle (GMSS) application adapts high-performance, high-quality, 5th/6th generation (C5/C6) Corvette brake components to your GM short-spindle equipped vehicle. This kit is ideal for those running factory spindles with or without the Guldstrand Modification, tall ball-joint kits, and other OE spindle based front suspensions designs. Please refer to the KORE3 GM Big-Brake Application Chart for details regarding specific vehicle compatibility. C5/C6 front components are a significant improvement over the original equipment drum and disc configurations that were available on the early A/F/X-Bodies. The C5/C6 rotors measure ø325mm x 32mm thick (ø12.80" x 1.26") and have either directional or pillar vane construction, providing higher brake torques, additional thermal mass, improved feel and better cooling for more aggressive, sustained driving without brake fade. C5/C6 front calipers are pressure cast aluminum with full width stiffening ribs in order to maximize caliper rigidity, extend service life, and improve pedal firmness and feel, all in a compact, lightweight package. The C6 calipers are interchangeable with the C5 calipers and are approximately 25% more rigid due to additional material across the bridge of the calipers. Both C5 and C6 calipers have twin ø40.5mm pistons and utilize a pad abutment design, where the braking torque is transmitted directly from the pads into the pad abutment brackets and the spindles they mounted to, leading to better performance you can feel at the pedal. There is vast aftermarket support for C5/C6 rotors and brake pads to suit nearly anybody's needs and/or budget. This KORE3 big-brake kit provides more braking performance per dollar than any other making it ideally suited for the front of almost any early A/F/X-Body application, whether you're grocery-getting, pro-touring, or a little bit of both. Notes: KORE3 GM short-Spindle kit is designed for forged short-spindles only, of which there are three (3) basic variations as shown below. The only definitive way to identify the spindle is based on the upper mounting boss. 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. KORE kit is compatible with many modular aftermarket drop spindles that use bolt-on steering arms similar in design to the OE spindles. Please contact us with any questions regarding such applications. Kit is 100% bolt-on. No welding, cutting, or grinding necessary when KORE3 components are used. Minimum ø17" wheels are required. Not all ø17" 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.
