Made of billet aluminum alloy and CNC machined to ensure the highest quality; Rotora's high performance brake system enables superior brake modulation while improving overall pedal feel to ensure equal distribution of weight transfer when braking. To achieve this proportional front-to-rear brake bias, Rotora’s opposing piston 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 full big brake system design delivers excellent initial bite, exceptional modulation, and consistent pedal feel for street and track use applications. All systems are ABS compatible and direct bolt on replacement with minimal modifications required. COMPONENTS/FEATURES: -Rotora billet aluminum alloy 4-piston racing calipers with sequentially sized piston bore sizes engineered to each specific vehicle. -Rotora billet aluminum hat with “floating” disc assembly to reduce heat related stress and unsprung weight. -Rotora one piece vented, or two piece heat treated directional vane disc system to improve airflow/cooling under severe braking. Slotted or drilled & slotted oversize discs up to 16” (405mm) to ensure equal heat dissipation and increase thermal capacity while relieving the disc and brake pad surface free of excess debris. -Rotora ceramic formulated pads designed for extreme street and track application with high co-efficient of friction and high temperature fade resistance. -Rotora DOT compliant stainless steel braided brake lines to improve stiffer pedal feel and prevent brake hose expansion. -Rotora carbon steel (SC45) mounting brackets (depending on application) and hardware. *This kit only comes 2-Piece front rotor set.
