Girodisc Slotted Rear Rotors For Porsche 991 GT3 Cup (992)

USP Motorsports is pleased to offer products from one of the top 2-piece brake rotors manufacturers, GiroDisc. GiroDisc's fully-floating design uses tension hardware to ensure that our rotors are silent on the street, but ready to go on the track. By specializing in this area, they have been able to dedicate their efforts to push their engineering and manufacturing to the highest levels in the industry. When GiroDisc was founded in 2003, they made their mission to design and manufacture 2-piece brake rotors that would perform flawlessly at the limits.

Customers around the world have found success maximizing the capabilities of their existing brake systems by installing GiroDisc rotors. This often negates the need for a pricier, more complex upgrade like a big brake kit. All Girodisc products are manufactured in-house using US-sourced materials which allows them to keep the highest standards possible.

The Girodisc system is a direct replacement for the OE disc, no modifications are necessary. The central hat section of Giro Disc rotors are made from strictly U.S. sourced 6061-T6 aircraft specification aluminum. The disc is made from their 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.
