GiroDisc 2-Piece Slotted Rear Rotors - 2020+ Toyota GR Supra 3.0L
Tax excluded. Shipping calculated at checkout
The Girodisc system is a direct replacement for the OE disc. No modifications are necessary. The disc will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency.  This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.
The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum.  The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc.  The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.
The rotor and hat have a floating mount system, which utilizes 10 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by class 12.9 screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.
Once the Girodisc system is in place, simply replace the cast iron rotor when needed.

What Is Your Return & Exchange Policy?
All processed orders that have not shipped will incur a 6% processing fee, this is mainly to cover any payment processing and cancelation fee with the manufacturer or warehouse. A processed order is an order that has already been put in our system and the product has been taken out of inventory and moving towards the packing and shipping face.
On special order or custom-made orders, the processing face is indicated when the manufacturer has received our order. Please be courteous and notify us ASAP if you wish to cancel any order(s) that were recently placed in order to prevent it from shipping out.
Due to the nature of racing and performance vehicles, no returns will be accepted on special order items, opened, installed, incomplete, or otherwise used products. If a product is ordered and not wanted, the UNUSED item can be returned within 30 days after the product has been delivered. This does not apply to SPECIAL ORDER items. Once the product is returned, you have two options for your refund:
You may have your purchase refunded back on your original payment method minus a 20% restocking fee of the total amount. In this case, please know that the initial shipping is not refundable (free shipping items still incur shipping chargers which MUST be deducted on a return). All items wanting to be returned MUST be reported within 30 days of delivery date. If you are still browsing and want an alternate product, we can provide you with a full credit minus shipping costs as a T1 Motorsports store credit. Some brands are excluded and may incur up to a 10% restocking fee. Please contact us to confirm.
On both refund options, a return shipping label may be provided if you are unable to ship the product(s) back using your own method of shipping. This shipping cost will be deducted from your total refund or credit.
