StopTech's Balanced Brake Upgrade equips your 135 with larger front or rear calipers and plus sized 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 big brake kits also include stainless steel brake lines and StopTech performance brake pads to complete the package.
The StopTech big brake kit uses StopTech's patented Two-Piece Floating Directional Aero Rotors. 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 BMW in Southern California as a U.S. Department of Transportation (DOT) registered supplier. Brake line material and fittings are all made from the highest quality parts available and feature a clear, abrasion-resistant cover for maximum protection against chaffing.
