GiroDisc 15-20 Alfa Romeo 4C Slotted Front Rotors
GiroDisc slotted front rotors are two-piece performance brake rotors built for 2015-2020 Alfa Romeo 4C models. The 320mm x 30mm slotted design clears brake dust and gases while curved vanes pull in cooling air to fight fade during track or spirited driving. Lightweight aluminum hats cut unsprung weight for sharper handling and quicker stops.
Key Features
- Slotted Surface: Sharp edges bite hard into pads and continuously clean friction material for consistent performance lap after lap
- Two-Piece Build: 6061-T6 aluminum hats reduce weight by 3.7 lbs per rotor compared to stock while allowing thermal expansion without warping
- High Carbon Ductile Iron Ring: Resists cracking under extreme heat and provides stable friction for repeated hard braking
- 72 Curved Vanes: Channel air through the rotor core to drop temperatures and extend pad life
- Patented Retention System: Stainless steel bobbins keep rotor ring centered on hat with zero play for precise operation
