TAG Motorsports is pleased to offer the GiroDisc McLaren 390mm Rear 2-Piece Slotted Rotors (part number A2-206) for the McLaren 750S / 765LT.

These GiroDisc 2-piece iron conversion rotors are for the rear of McLaren 765LT and 750S with the upgraded (MSO) track brake package. These are 390mm in diameter versus the 380mm rear rotors used in the standard brake package. They are a direct replacement for the factory carbon ceramic rotors. When used with our rear pads, the conversion does not require any modifications to the calipers or other components.

The rotor rings are machined from a proprietary casting made of high-carbon iron formulated to GiroDisc’s specifications. This superior metallurgy results in a rotor that holds up better, and the 72 curved vanes act as a centrifugal pump pulling air in through the hub to effectively cool the rotors under hard use. The 2-piece design means a reusable hat which can be attached to new rings (part number D2-206) when they need to be replaced.

All major components including the hats, rotor rings, and drive pins are manufactured in-house at our facility in Bellingham, WA from domestically sourced materials. The hat is made from 6061-T6 aluminum and coated in a black anodize finish. The drive pins are made from a high-strength steel alloy and cadmium-plated for corrosion resistance. All rotors are assembled with spring clips and Belleville washers for race-ready float while also being street-friendly with no noise from loose hardware.

Diameter: 390mm

The minimum thickness at which we recommend replacing these rings is 32mm. We also recommend replacing them if a crack leads to the edge of the ring.
