Adding StopTech ST-40 front calipers to your WRX as part of the Balanced Brake Kit will give you the advantage of 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 StopTech big brake kit uses StopTech's patented Two-Piece Floating Directional Aero Rotors with your choice of several rotor diameters, 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.
StopTech makes their own stainless steel brake lines for your WRX in Southern California. StopTech's brake lines feature a clear, abrasion-resistant cover for maximum protection against chaffing.
The supplied StopTech performance street pad is and excellent choice for the daily driven STI and function great for the occasional autocross. If regular trips to autocross events or track days are in your STI's future, be sure to purchase a more appropriate pad for those events.
