The KORE3 ø325mm C5/C6 Front Big-Brake Kit for the Chevy Impala SS tall-spindle application adapts high-performance, high-quality, 5th or 6th generation (C5/C6) Corvette brake components to your vehicle. Please refer to the KORE3 GM Application Chart for details regarding specific vehicle compatibility.
KORE3 big-brake kits are a significant improvement over the OE B/D-body brake which tend to be severely rotor limited. The OE rotor is only ø11.88" x 1.04" and has less than optimal straight cooling vanes. Due to insufficient rotor mass when compared to the overall weight of the vehicle, they are prone to fading when driven aggressively. 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 GM tall-spindle application, whether you're grocery-getting, pro-touring, or a little bit of both.
Notes:
- KORE3 Big-Brake Kit for GM B/D-body vehicles is compatible with all GM tall-spindles that use SET6 inner wheel bearings and SET3 or SET34 outer wheel bearings.
- Kit installation requires moderate, irreversible spindle modifications with basic
metal fabrication tools. All necessary modifications are detailed in the instructions.
- Minimum ø17" wheels are required depending on rotor size and caliper selection. Not all ø17" wheels will fit. The OE ø17" Impala SS wheels may require a thin spacer and/or a small amount of clearancing between the wheel and the pad abutment brackets. 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.
