Race Technology Used By Turner Motorsport StopTech Brakes puts championship-winning race technology and state-of-the-art engineering under your feet. StopTech's Rear Big Brake Kit for the E9X M3 is 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
+ 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

Maximizing brake efficiency by braking with all four wheels... Sounds obvious right? Many bolt-on caliper upgrades and other big brake kits are not built with the specific vehicle's dynamics in mind. With too much braking force on the front, rear traction is compromised. And vice-versa. Brake traction is better when all four tires are doing the work. Most BMWs have 50-50 weight distribution so the correct braking proportioning is crucial! StopTech engineers each kit around that vehicle's dynamics by altering the size and number of pistons in the caliper to match the rotor size used in the kit. Bigger is not always better...

Big brake kits have larger components than the factory brakes. Some wheel designs and sizes may not clear without wheel spacers. StopTech has produced a template that has all of the critical dimensions of this brake kit. You can download and print it here and then check the clearance on your wheels.
