Rolloface 2 Piece Replacement Rotors (Rear) - Honda Civic Type R FK8 17+
The primary purpose of the Rolloface 2 piece replacement rotors is to reduce unsprung and overall vehicle weight. The secondary purpose is to increase the ventilation and cooling capacity of the brake disc while retaining it’s original dimensions. This is accomplished by using two-piece disc construction. The central “hat” section of the disc is made from 6061-T6 aircraft specification aluminum.
Rolloface Performance introduced the RF J type rotor to the general public in 2 piece replacement brake rotors. The release of the RF J type pattern brought the benefits of a cross drilled and slotted rotor.
The RF J type rotor design. The primary benefit is the increased durability and longevity. For years cross-drilled rotors have been recognized as the best rotor to provide excellent initial bite and additional grip on the pad. As the brake pad grabs the rotor the leading edges of the RF J TYPE create additional bite on the pad face and provide the driver with a much more positive feedback in braking performance.
Additionally a drilled rotor can potentially form cracks from rapid expansion and contraction during hard use caused by dramatic changes in rotor temperatures. Because the RF J type machining process does not penetrate through the rotor, it prevents the rotor from forming surface cracks and therefore, can withstand harder driving and high temperatures.
The disc is made from cast iron, to the same specification and material as used by professional racing organizations. It is a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc. The rotor and hat have a floating mount system, which utilizes high strength alloy steel drive pins, manufactured by Rolloface to our own specifications and & polished chrome plated for a long lasting corrosion resistance. The 12 point flange bolts are secured by grade 12 cap screws with hardened washers.
