Description
GiroDisc Slotted Front Brake Rotors – Porsche 996 GT3 Cup / GT3 R – 350mm
Upgrade or replace the front brake rotors on a compatible Porsche 996 GT3 Cup or GT3 R with GiroDisc’s 350mm slotted front brake rotor system.
Developed for high-performance and competition braking applications, these rotors feature a slotted cast-iron friction surface designed to withstand the repeated heavy braking and thermal cycling encountered during track use.
Designed for Porsche 996 GT3 Racing Applications
The Porsche 996 GT3 Cup and GT3 R were developed for competition, where brake performance, durability, and serviceability are critical.
GiroDisc’s 350mm front rotor offering provides an alternative for race teams maintaining these earlier Porsche GT3 platforms.
Because rotor configurations can differ between GT3 Cup, GT3 R, and road-going GT3 models, the existing brake assembly should be verified before ordering.
Slotted Racing Friction Surface
The GiroDisc friction surface incorporates machined slots intended for demanding track and racing applications.
The slotted design helps maintain the brake pad-to-rotor interface during repeated braking cycles and provides an alternative to cross-drilled friction surfaces.
Designed for Demanding Track Use
Competition braking subjects rotors to repeated high-temperature operating cycles.
The GiroDisc rotor design is intended to provide a durable friction surface for performance and racing brake pads, making it suitable for the demanding braking conditions encountered in Porsche club racing and motorsports.

Porsche 996 GT3 Cup Fitment – 2002–2005
The GiroDisc A1-151 front brake rotors are designed for the 2002–2005 Porsche 996 GT3 Cup equipped with the later 350mm front brake system.
Applications:
- 2002–2005 Porsche 996 GT3 Cup: Direct replacement for compatible 350mm front brake systems.
- 1998–2001 Porsche 996 GT3 Cup: Compatible only when the car has been upgraded to the later 350mm front brake configuration.
Earlier 996 GT3 Cup cars originally used 330mm front brake rotors. Upgrading these cars to the later 350mm brake system is a popular modification, but the original 330mm brake configuration is not compatible with these rotors.
Important: Verify the existing rotor diameter, caliper configuration, and mounting arrangement before ordering. Vehicle model year alone may not identify the brake system currently installed.
