The KORE3 ø325mm C5/C6 Front Big-Brake Kit for the 4th generation GM F-Body (GMF4) applications adapts high-performance, high-quality, 5th/6th (C5/C6) generation Corvette brake components 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 C5/C6 rotors measure ø325mm x 32mm thick (ø12.80" 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 C5/C6 rotors versus the straight vane F-body rotors increases the overall cooling efficiency of the system, 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 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 4th generation F-body, 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 ø17" wheels are required with C5/C6 ø325mm rotor kits for caliper to wheel clearance. All 1996 and later 17" F-body wheels fit, however not all aftermarket ø17" wheels fit. Minimum ø18" wheels are required with the 340mm and 355mm kits. 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.
- ABS is unaffected by the addition of this KORE3 big-brake kit.
