GiroDisc 2015+ Ford Mustang GT Mach 1 (S550 w/Perf Pkg Brembo Front Caliper) Slotted Front Rotors
GiroDisc slotted front rotors deliver direct replacement braking upgrades for 2015-2023 Ford Mustang GT Mach 1 and GT models with S550 chassis and Performance Package Brembo front calipers. The two-piece construction with curved vane design sheds over 12 lbs total unsprung weight versus stock while boosting heat dissipation for consistent track and street performance. Slotted surfaces enhance initial bite clear pad gases and evacuate water for reliable stops in all conditions.
Key Features
- Two-Piece Design: 6061-T6 aluminum hats with 72 high-carbon alloy rotors connected by aircraft-grade stainless steel bobbins reduce rotating mass by 6.2 lbs per rotor compared to OEM 29.4 lb castings.
- Directional Slotted Face: Curved slots wipe away debris improve modulation and maintain pad contact for shorter stopping distances without noise or vibration.
- Curved Vane Core: Internal vanes increase airflow by 30% over stock straight vane pulling heat away from friction surface to prevent fade during hard use.
- Cryo Treatment: Rotors undergo cryogenic processing and 48-hour stress relief for denser microstructure that resists cracking warping and extends service life.
- Precision Balanced: Factory balanced assembly ensures smooth operation at high RPM with no runout compatible with OEM ABS and traction control systems.
