The KORE3 Ø355mm Hybrid Front Big-Brake Kit for the 4th generation GM F-Body (GMF4) applications adapts a combination of the larger C6 Z06 rotors and the more cost effective 2-piston C5/C6 Corvette calipers to your LT1 or LS1 Camaro or Firebird. 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 LT1 (Ø10.93") and LS1 (Ø11.93") F-body brake packages. The C6 Z06 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 increases the overall cooling efficiency and rigidity of the rotors versus the OE straight vane F-body rotors, resulting in maximum braking performance and minimum 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 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.
- This KORE3 big-brake kit is designed for GM 4th generation F-body spindles only, of which there are two (2) variations, both of which are compatible with this KORE3 kit.
- Kit installation requires minor to 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 Ã¸355mm 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.
- ABS is unaffected by the addition of this KORE3 big-brake kit.
