RH rotor and top hat subassem.

The right-hand brake rotor and top hat subassembly is the complete floating rotor unit for the right side of the Rush SR. It pairs the 274mm × 25mm floating 26-vane disc with its aluminum hat (bell), assembled and ready to install. The floating design allows the outer rotor ring to move laterally on its bobbins, reducing heat transfer to the hub and helping maintain consistent pad contact under racing conditions.

This is an OEM replacement part — the same rotor assembly that comes standard on the Rush SR. Rotors are rated for 100+ hours of use, though actual service life depends on driving style, track conditions, and how well the brakes are maintained. When replacing, always inspect the rotor bobbins and torque them to 15 ft-lb (20 N-m) using a distorted thread lock nut.

The Rush SR uses the "2593" pad shape across all four corners. Replacement pads must be 14.6mm thick — 15mm pads will not fit. Compatible pad options include the required 2026 spec front or rear race pad sets, as well as Hawk HB180, Performance Friction PFC-11/13, G-Loc R12, and Carbotech XP8.
