Porsche GT4 Clubsport Front Rotors (380x32)
The Girodisc system is a direct replacement for the factory cup car discs on the Porsche GT4 Clubsport. No modifications are required—the rotors bolt directly to the car and integrate perfectly with the OEM calipers. This upgrade provides exceptional cooling capacity, lighter weight, and superior durability compared to factory rotors, making it ideal for both professional racing and advanced track-day drivers.
Motorsport-Grade Design, Made in the USA
Each Girodisc rotor is precision-engineered and manufactured in-house using premium domestic materials. The central hat section is CNC-machined from 6061-T6 aircraft-grade aluminum, while the rotor rings are cast from Girodisc’s proprietary high-carbon iron alloy. This combination delivers outstanding thermal stability and braking consistency under the harshest track conditions. The 380x32 mm size provides increased surface area and heat capacity to reduce fade during extended sessions.
