Please note that these rotors are available as an add-on option to our IS-F rear four piston upgrade kit!

Our new line of Competition 2-piece rotors significantly improves braking performance, reduces unsprung & rotational weight, and improves the aesthetics of your braking system. These are the only rotors on the market for the RC F and IS-F that were race proven. They have true two piece floating design with superior materials and finishing unmatched by any product on the market today.

Rear Rotor Weight: Stock (23lbs each), RRRacing (17.3lbs each). Total Weight Savings Rear = 11.4lbs!

Our Discs are made from a proprietary alloy, exactly the same specification as used throughout professional racing. Discs feature directionally curved cooling vanes, and are zinc plated for corrosion resistance. The center “hat” section of the disk is CNC machined from 6061-T6 aircraft specification aluminum. The hat and the disc are attached with sprung pins, allowing for a “fully floating” design, and accommodation of thermal expansion and contraction between the disc and hat without causing cracking under high performance use (as is typical in 1 piece rotor, or fixed 2 piece rotor construction).

Please note that had color matches our front IS-F two piece rotor hat color and slightly greyer than in this photo.

And of course, in order to ensure the quality of our products, all of our components are made in the USA by Girodisc, including the discs and hats.
