Girodisc Front Steel Disc Upgrade – 380mm – Porsche 991 GT3 / GT3 RS (Steel Brakes)
Product Description
Upgrade Your Factory Steel Brakes for Peak Performance
This Girodisc front steel disc upgrade kit is a direct replacement for the OEM 380mm single-piece cast iron front discs fitted to factory steel brake Porsche 991 GT3 and GT3 RS models. Built for demanding track use and aggressive road driving, this 2-piece floating rotor setup enhances heat resistance, reduces unsprung mass, and improves pedal feel — all while maintaining compatibility with the OEM red calipers and brake lines.
Why Choose Girodisc?
The factory discs are good — but Girodisc takes it further with a purpose-built motorsport solution:
-
Reduced unsprung weight for sharper handling and suspension response
-
Directional curved vanes for efficient cooling under repeated hard braking
-
Increased resistance to cracking and thermal stress
-
Compatible with performance pads such as Ferodo DS3.12, Endless ME20/22, or PFC 08/11
🔧 Note: These rotors are designed for Porsche 991 GT3 / GT3 RS models that came with steel brakes (red calipers) from the factory. If your car has PCCB (carbon ceramic brakes with yellow calipers), you’ll need the larger 410mm Girodisc kit...
