To achieve this proportional front-to-rear brake bias, Rotora's 2-piece cast aluminum calipers are fine tuned by increasing the clamp load to the optimal level while utilizing the stock master cylinder to retain overall front-to-rear brake bias. Rotora's high performance brake system is comprised of a set of 1 or 2-piece cross-drilled/ slotted or slotted directional rotors (295-355mm), a set of high performance (2, 4, or 6-piston) calipers, carbon steel (S45C) mounting brackets, Rotora ceramic friction material race pads, and stainless-steel braided brake lines (D.O.T. compliant). All Rotora brake systems are direct bolt on replacement with minimal modifications required.
