The KORE3 Ø355mm Hybrid Front Big-Brake Kit for the 3rd generation GM F-Body (GMF3) applications adapts a combination of the larger C6 Z06 rotors and the more cost effective 2-piston C5/C6 Corvette calipers to your Camaro or Firebird. Please refer to the KORE3 GM Big-Brake Application Chart for details
regarding specific vehicle compatibility.
C6 Z06 rotor combined with the 2-piston C5/C6 calipers offfer a huge improvement over the original Ø10.5" x 1" disc and single-piston, cast iron calipers that were standard on the GMF3 applications and significantly better than the Ø12" x 1.1" 1LE-performance package offered on some 1988-1992 models. The C6 Z06 front rotors measure Ø355mm x 32mm thick (Ø14.0" x 1.26") and provide higher brake torques and additional thermal mass for more aggressive, sustained driving. Additionally, the directional or pillar vane design of the C6 Z06 rotors versus the straight vane F-body rotors increases the overall cooling efficiency of the system and rigidity of the rotors, resulting in maximum braking performance while minimizing brake fade and NVH.
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 mount to, leading to better performance you can feel at the pedal.
There is excellent aftermarket support for C6 Z06 rotors and C5/C6 brake pads to suit nearly anybody's needs and/or budget. This Ø355mm KORE3 Hybrid big-brake kit is an easy upgrade from the base level Ø325mm kits and adds even more thermal capacity for those who push their cars to the limits and beyond. Whether you're looking for added resistance to fade or trying to fill some big wheels on a budget, the Hybrid kit may be for what you're looking for, whether you're grocery-getting, pro-touring, or a little bit of both.
Notes:
- KORE3 GMF3 Kit is designed for 1982-1992 GMF3-spindles that were originally supplied with th single-piston cast iron calipers only. Brackets are not compatible with 1LE spindles.
- Kit installation requires moderate, irreversible spindle modifications with basic metal fabrication tools. All necessary modifications are detailed in the instructions.
- Minimum Ø18" to Ø19" wheels are required with KORE3 Ø355mm Hybrid big-brake kits for caliper to wheel clearance, however not all ø18" to ø19" wheels fit. Please verify fitment prior to ordering using the appropriate KORE3 fitment template. Wheel fitment is the buyer's responsibility. Please contact us if you have any questions regarding your specific application or the proper use of the templates.
