A properly set up Manual Brake Conversion Kit improves lap times and makes for a more controllable drift / rally / road race car.

Changing the pedal ratio to 6:1 is a major function and feel upgrade to allow the use of a larger master cylinder. The OE pedal ratio can only leverage so much, so were limited to a 3/4 or smaller master cylinder. The improved Motorsport pedal ratio gives you a better mechanical advantage with additional leverage. This means we can use a larger 1 inch master cylinder with more fluid being pushed per mm of piston travel inside. It allows you to have a better braking feel and more force to the calipers with equal or lesser force at the pedal. That translates to less leg effort and more braking power while keeping a similar throw distance.

How can we achieve pedal box function seen in F1, Indy, IMSA, & GT4 without $3,000+ in parts? Without days of prep, relocation of under-dash components, and fabrication? How can we have a DUAL Piston / Isolated Front and Rear Circuits setup thats approved for nearly every sanctioning body from FIA to Formula Drift plus SAE and DOT approved? How can we achieve this without removing and drilling the stock pedal or without massive modifications to the firewall or interior? After years of hard work, testing, and procurement…Chase Bays has it figured out.
