The original BMW Dual Caliper solution! This dual caliper bracket kit is the easiest and least intrusive way to install a true Formula Drift style secondary/dual rear caliper setup for hydraulic handbraking; aka making mad skids! Don’t 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 designed by professional automotive engineers in the USA to be as strong as possible with no compromises, are manufactured in our own machine shop out of aerospace-grade 6061 aluminum, uae ARP hardware and are all 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 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.

E82 135i and E9X 335i models are designed for:

  • Wilwood GP320 calipers (RH Wilwood 120-10714; LH 120-10715)
