GM F-BODY, 1993-2002, 340mm C6 Z51

The KORE3 340mm C5/C6 Z51 Front Big-Brake Kit for the 4th generation GM F-Body (GMF4) applications adapts high-performance, high-quality, 5th/6th generation (C5/C6) Z51 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 Z51 front components are a significant improvement over the original equipment LT1 (10.93") and LS1 (11.93") F-body brake packages. The C6 Z51 rotors measure 340mm x 32mm thick (13.4" 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 Z51 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 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 40.5mm 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 Z51 rotors and C5/C6 brake pads to suit nearly anybody's needs and/or budget. This ø340mm KORE3 big-brake kit is an easy upgrade from the base level 325mm kits ands adds even more thermal capacity for those who push their cars to the limits. Any 4th generation F-body running ø18" or larger wheels can benefit from the addition of this kit, whether you're grocery-getting, pro-touring, or a little bit of both.

Notes:
  1. 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.


  2. Kit installation requires minor to moderate, irreversible spindle modifications with basic metal fabrication tools. All necessary modifications are detailed in the instructions.


  3. Minimum 18" wheels are required with C5/C6 Z51 340mm diameter rotor kits for caliper to wheel clearance, however not all 18" 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.
