The original BMW Dual Caliper solution! This dual caliper kit is the easiest and least intrusive way to install a true FD style secondary/dual rear calipers setup for hydraulic handbraking; aka making mad skids! Dont use an in-line system which can lead to constantly changing brake bias and pedal feel. Use this for consistent and reliable sideways action!


Our brackets are desgined by professional automotive engineers in the USA, manufactured in our own machine shop, and shipped directly from our door to yours. No BS, we stand by our product no matter what as we create it from start to finish. Feel free to reach out with any questions anytime during your build.


With this kit you can install a hydraulic handbrake for epic drift entries, controlled slides in rallies, and tight corners in autocross- all with just a few simple bolt on parts.
