StopTech's Big Brake Upgrade equips your 2015-176 Subaru WRX with larger, 4 piston front calipers and plus sized 355 x 32 StopTech AeroRotors. StopTech big brake kits provide a neutral biased brake system that will improve safety and performance on and off the track as well as add a striking visual enhancement that is second to none. StopTech BBKs also include stainless steel brake lines and StopTech Performance brake pads to complete the package.
StopTech ST-40 BBK's offer one of the stiffest calipers on the market. StopTech's calipers incorporate their bolt-in bridge, which is strong enough to dramatically reduce caliper distortion yet does not sacrifice the caliper's cooling. The squeeze forged StopTech calipers have the least flex of any tested after market or OEM caliper. The air channel in the bridge is designed to help air flow through the retainer, resulting in better cooling. Expect improved performance and pedal feel from the stiffer caliper without added vibration, noise or pad taper.
StopTech's big brake kit uses a patented Two-Piece Floating Directional Aero Rotors featuring their innovative leading and trailing edge designed cooling vanes. The unique vanes inside the disc maximize airflow through the AeroRotor to reduce turbulence and flow more air than any rotor tested. AeroRotors provide up to 80% better airflow over original equipment rotors and 10-30% better airflow than other directional vaned racing rotors. Cooler rotors are less prone to warping and cracking, and will also help to prevent brake fade and/or failure.
StopTech's stainless steel brake lines and fittings are manufactured from the highest quality parts available. StopTech's brake lines feature a clear, abrasion-resistant cover for maximum protection against chaffing. Quality control procedures are in place to ensure lines are the correct length and every fully assembled StopTech stainless steel brake line is tested to a pressure of 4,500 psi.
The supplied StopTech performance street pad can be used for daily drivers as well as the occasional autocross. *The pads should be upgraded if the car is tracked regularly.
StopTech big brake kits calipers are commonly available in red or black with the Trophy kits coming in a dark gray anodized finish. Please call to order other colors.
Anti-corrosion gold zinc coating is recommended for cold climates, where snow and road salt are encountered. It is also recommended for to reduce visible surface rust on the vanes and the outer circumference of the rotors. *This option will add to lead times, please call for more information.
