2 Piece Replacement Rotors 2017-2019 Honda Civic Type R FK8 – Rear 304*11mm $648.00 Motorsports technology brought to the road and track. The Rolloface 2-piece replacement rotors are made from high-strength (high-carbon) cast iron similar to the rotors used in race applications. The rotors are manufactured to exacting standards and feature machined grooves in a J-type shape that helps swipe gases and brake dust from the brake pad to provide strong initial bite during brake pedal application. The 2-piece design features the rotor and a 6061-T6 aluminum center “hat” that attaches to the wheel hub and rotor. By attaching the rotor to the center hat with high-strength, chrome-polished and polished drive pins, Grade 12 cap screws and hardened washers, it creates a floating rotor design. The floating rotor design provides for even distribution of brake pad pressure while also reducing weight when compared to many OEM brake systems. To help increase cooling, the rotor features an internally curved-vane design that helps circulate air. Our system is lighter than most OEM braking systems to help reduce un-sprung weight, which benefits acceleration, braking and handling. The aluminum center hat of the Rolloface 2-piece replacement rotor system is also available in over 6000 different colors for a customized appearance, at no extra charge.
