GiroDisc Slotted Rear Brake Rotors Nissan Skyline GT-R R32 V-Spec / R33 / R34 1989-2002 | A2-357

Stock rear rotors on a Skyline GT-R are heavy, one-piece units, and that extra unsprung weight fights your suspension every time the wheel moves. GiroDisc's 2-piece rear rotor swaps that solid iron disc for a floating rotor ring mounted to a lightweight aluminum hat, cutting rotating mass at the corner where it matters most for both handling response and brake feel.

Each ring is machined from a proprietary high-carbon iron casting built to GiroDisc's own specification, with 48 curved vanes that pull air through the hub and cool the rotor under hard, repeated use - the kind of use a stock rotor starts to fade under on a track day or a long canyon run. The hat is 6061-T6 aluminum, black anodized, and stays on the car permanently - when the ring wears down, you replace just the ring (part D2-357) instead of the whole assembly. Spring clips and Belleville washers hold everything together with race-capable float, and no rattle or hardware noise on the street.

Every hat, ring, and drive pin is machined in-house in Bellingham, WA from domestically sourced material - this isn't an off-the-shelf casting with a sticker slapped on it, it's a rotor built specifically for this chassis.

Fitment: Nissan Skyline GT-R - R32 (V-Spec), R33 (all), R34 (excluding V-Spec II). Rear position, 300mm.
Note: Rear pad backing plates need to be trimmed flush to the pad material for correct fitmentt. Contact GiroDisc directly if you'd like pre-trimmed pads or have fitmentt questions.
