Important Note:

Brakes are a safety critical part of a motor vehicle. Brake components should be installed by a competent mechanic in a professional manner. Any incorrect installation of brake components can cause a major safety problem or an accident. If you are not a competent and qualified mechanic you should not attempt to install these products, but should take the vehicle to a vehicle dealer or competent automotive mechanic for their installation.


Disc brake pads and rotors are wear items and as such, should be inspected regularly and replaced as necessary. Read More.

Featuring larger rotors that increase heat capacity, StopTech Big Brake Kits allow drivers to brake harder with every stop. The two-piece AeroRotors® increase airflow for better cooling, less fade and longer rotor and pad life, while stiffer, fully forged calipers with patented, removable bridges provide better clamping and less pad taper. Additionally, the kit's stainless steel brakelines reduce system compliance to provide a consistent pedal feel and confidence-inspiring responsiveness.

Without disturbing the vehicle's stock front-to-rear brake torque ratio, StopTech's Balanced Brake Upgrade® design precisely apportions front and rear braking resources while factoring in the vehicle's weight transfer under braking. Shorter stopping distances, increased tire traction and improved control of brake input are ensured via this design philosophy.
