Upgrade to 2 piece rotors (slotted), (4) piston calipers (black), & high performance pads
Featuring fully forged calipers with patented stiffening bridges, patented 2-piece AeroRotors® for optimized cooling, braided stainless steel brake lines, performance brake pads, mounting brackets and all necessary hardware to complete the installation. StopTech® Big Brake Kits were the first Balanced Brake Upgrades® on the market, offering optimized brake bias to utilize all the traction available from all four tires.
StopTech® 2-piece calipers have the lowest amount of flex and deflection among 25 of the leading caliper models (including some monoblocks) from well-known manufacturers. This is accomplished using StopTech's® patented bolt-in bridge, which is strong enough to stop distortion without sacrificing cooling through the top of the caliper.
StopTech® has developed several design innovations to improve rotor airflow. The patented 2-piece AeroRotors push more air thanks to curved, airfoil-shaped vanes and an air channel that widens at the trailing edge of the vanes. StopTech aluminum AeroHats are lighter, and feature directional stand-offs between the rotor and mounting hat that increase airflow to the (hotter) outside face of the rotor by over 15%.
StopTech® Street Performance Brake Pads are included in all Big Brake Kits besides the track-only Trophy Race Big Brake Kits. StopTech Street Performance Pads are intended for high performance street driving as well as light duty track use.
- Aggressive pad for high performance street driving
- Para-aramid composites provide linear response regardless of pad temperature
- 100% positive molded for uniform friction material density
- Low dust formulation is rotor friendly and leaves wheels cleaner
- Scorched to raise initial cold effectiveness and ease bed-in
- 100% Asbestos-free formula
