StopTech Brakes puts championship-winning race technology and state-of-the-art engineering under your feet. StopTech's Front Big Brake Kit for the E90 M3 is a model-specific brake upgrade engineered to work with the stock brake hydraulics and ABS/DSC system. StopTech builds each kit around the specific vehicle, engineering the system to achieve the correct brake balance. This brake upgrade gives better stopping performance in everyday driving, aggressive street driving, or all-out track days. By increasing the rotor size, using a larger pad, and a fixed forged aluminum caliper, you can improve your braking performance substantially for any condition! StopTech Brakes have been used on Turner Motorsport racecars since 2003, winning 5 sports car championships and recording numerous race wins since.
Safety Improvements from A Big Brake Kit:
- Caliper design improves brake application and increases torque - braking is stronger meaning shorter stopping distances and faster response
- Vehicle-specific design - improves brake feel with a firmer pedal
- Larger and thicker rotors - less fade and longer pad and rotor life
Advantages of a StopTech Big Brake Kit:
- extremely strong caliper and mounting system - reduces flex and deflection, improving torque application to the disc
- Several color options available
- Vehicle-specific calipers that maintain correct brake proportioning and balance
- AeroRotor patented vaning for superior air flow
- Cross-Drilled for street use or Gas-Slotted for street or track use
- Billet aluminum mounting hats for superior strength over steel
- DOT-compliant stainless steel brake lines
- Street Performance brake pads that work on both street and light track use
