Girodisc Ford SN95 Mustang Front Rotors

The Girodisc system is a direct replacement for the OE front rotors on all 1994–2004 Ford Mustang Cobra, Bullitt, and Mach 1 models. These rotors will also fit vehicles equipped with OEM Cobra R or SVT Focus Brembo calipers with only minor modification to the pad backing plate for clearance. This lightweight, high-performance rotor upgrade enhances stopping power, cooling efficiency, and handling balance without affecting the factory brake bias or ABS calibration.

High-Performance Construction

The central hat section is precision-machined from U.S.-sourced 6061-T6 aircraft-grade aluminum for maximum strength and reduced weight. The rotor rings are Girodisc’s proprietary high-carbon cast iron, poured and machined entirely in-house in the USA. The curved vane design, inspired by motorsport applications, functions as a centrifugal pump, drawing air through the rotor for superior heat dissipation and consistent braking performance.

FAQs

Will these fit my Mustang without modifications? Yes, they fit directly on all Cobra, Bullitt, and Mach 1 models. Cars with OEM Brembos may need slight pad backing plate grinding.

Do these rotors reduce weight? Yes. Girodisc rotors are significantly lighter than factory units, improving both acceleration and suspension performance.

Are they noisy during normal use? No. Anti-noise spring washers prevent rattles and maintain quiet street operation.

Can I replace just the iron rings? Yes. The system is fully rebuildable, allowing easy replacement of worn rings while reusing the aluminum hats and hardware.
