BMW Big Brake Kits, Street, Race & New Lug-Drive Technology

Posted on Jul 23, 2020

When it comes to engineering big brake kits for your BMW, whether for heavy street use, light track days, autocross, or competitive wheel-to-wheel racing, Wilwood has the experience and expertise to provide you exactly what you need and at a price that will make you smile. Our big brake kit upgrades are a perfect complement to wheel, tire, and suspension upgrades when using your stock spindles.

Wilwood has a history of racing born over four decades ago. Engineering and manufacturing bolt-on compatible brake kits are our specialty and we do it all right here in the USA. Each kit is specifically built to fit your year-make-model using factory spindles and to work with all factory electronics, including your ABS and OEM master cylinder. Our engineers take the time to analyze each kit and provide clear-cut installation instructions for each application. You'll find just about every minute detail regarding your kit on our website, from wheel clearance, piston bore sizes, rotor sizes and specs, fit and finish information, and a schematic to easily identify parts in the kit plus those on your car and how they integrate.

Most kits will include properly sized DOT stainless steel flexline brake lines to connect your car's hard lines to the new calipers. With most street-use applications, a front upgrade kit is all that is needed for improved performance (and improved aesthetics) while still maintaining the braking balance of the car. However, rear brake kits are available for many E9x body styles, most M3 models, and all road race kits.

The majority of brake kits will include Wilwood's highly-respected GT 72 curved-vane Spec37 rotors with proprietary iron alloy to withstand extreme heat, resist warping, cracking and excessive wear. The technology has been engineered and developed from our 40+ years of racing experience.

If no options are displayed it doesn't mean we don't have what you are looking for. We partner with many experienced fabricators, specialty parts distributors, chassis builders, and bespoke companies who build kits using Wilwood components for your application.

Wilwood's road race big brake kits feature a hard anodized finish for superior wear resistance, and are engineered for high-heat environments utilizing our proprietary Thermlock® piston technology providing a stainless steel heat shield to minimize heat transfer to pads, pistons, seals, and brake fluid. Originally developed for NASCAR and other professional road-race categories, Wilwood now includes them as standard in all ST-designated (Short Track) racing calipers.

When it comes to road racing kits for your BMW, Wilwood is setting the trend in new technology with the introduction of our Dynamic GT Rotor and Lug Drive Hat assemblies utilizing a snap-ring instead of bolts to retain the hat to the rotor. The benefits from this type of setup are huge in terms of product longevity, heating and cooling differences between hat and rotor materials, and the speed at which you can change rotors - even while hot.
