Ford Shelby GT350 Front Rotors (Girodisc A1-162)
The Girodisc Front Rotor set for the Ford Shelby GT350 provides a performance-focused upgrade that enhances braking response and heat management while maintaining perfect compatibility with the factory calipers and pads. Designed as a direct replacement for the OEM discs, these rotors bolt on with no modifications required and retain factory brake bias and ABS functionality.
Vehicle Fitment
This Girodisc front rotor set fits the following models:
- Ford Mustang Shelby GT350 (2015–2020)
- Ford Mustang Shelby GT350R (2015–2020)
Direct OEM replacement; works with stock calipers and pads. No modifications or adapters required.
Performance and Design
Each Girodisc rotor features a two-piece floating design with a 6061-T6 aluminum hat and proprietary cast iron friction rings, both manufactured in the USA. This design significantly reduces unsprung and rotational mass, improving suspension response and acceleration. The internal curved vane structure acts as a centrifugal pump, forcing air through the disc to increase cooling efficiency during repeated high-performance braking.
Features
- Direct bolt-on replacement for OEM rotors; no modifications needed.
- Two-piece floating rotor design reduces unsprung and rotating weight for sharper handling.
- 6061-T6 aluminum hat with proprietary cast iron friction rings for optimal strength and heat capacity.
- Curved vane internal design enhances airflow and heat dissipation under heavy braking.
- Floating mount system with 12 high-strength alloy steel drive pins allows precise axial and radial float.
- Anti-noise spring washers eliminate rattle during normal street use while maintaining full float under race conditions.
- Cadmium-plated hardware and class 12.9 fasteners ensure long-term corrosion resistance and durability.
- Designed, cast, and machined entirely in the USA to motorsport-grade specifications.

FAQs: Ford Shelby GT350 Front Rotors (Girodisc)
Do these rotors work with the OEM pads and calipers? Yes. They are designed to bolt directly to the factory calipers and work perfectly with OEM or aftermarket pads.
What improvements can I expect over the stock rotors? Reduced unsprung weight, improved cooling, and more consistent braking performance under high heat conditions.
Are these rotors noisy like typical floating designs? No. The use of anti-noise spring washers prevents rattle during daily driving while preserving full float under heavy thermal expansion.
Can I service these rotors later? Yes. Once the cast iron friction rings wear out, you can replace only the rings while retaining the aluminum hats and hardware.
