Product Description
These GiroDisc 2-piece rotors are a direct replacement for the rear rotors on the Toyota GR Supra with the 3.0L motor, as well as BMW G-chassis cars with a 345mm rear rotor.
Our 2-piece, fully floating assemblies help shed unsprung weight and rotating mass from the front axle of the vehicle. The rotor rings are machined from a proprietary casting made of high-carbon steel formulated to GiroDisc’s specifications. This superior metallurgy results in a rotor that holds up better, and the 48 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 D2-307) 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. The minimum thickness at which we recommend replacing these rings is 22mm. We also recommend replacing them if a crack leads to the edge of the ring.
Product Features:
* Sold As Pairs.
* US 6061-T6 aluminum makes our rotor's center hat.
* Girodisc's cast iron and in-house machining make the disc.
* Racing-inspired curved vane rotors cool the disc.
* 2-Piece Slotted Performance Brake Rotors use 8 or 10 cadmium-coated high-strength steel-driving pins made in the USA.
* GiroRotors retain brake bias and ABS with OEM calipers.
* Pins maintain axial and radial float between hat and disc while braking.
* Includes cap screws to protect pins.
* The rotor side pins have anti-noise spring washers to prevent cold rotor noise.
* Rotor expands with heat without rattling or noise.
* Float design self-centers the rotor.
