GiroDisc 15-20 Alfa Romeo 4C Slotted Rear Rings

These GiroDisc slotted rear rotor rings are made for the 2015-2020 Alfa Romeo 4C. They are designed to replace the factory rotor rings, offering improved performance for drivers who push their cars hard. If you're tracking your 4C or just want a more consistent feel during spirited driving, these are a solid option.

GiroDisc uses a well-built, high-carbon iron alloy for the friction surface. This material is chosen for its ability to handle heat without warping or cracking, which is crucial for performance braking. The rings are slotted, meaning they have machined grooves across the braking surface. These slots help to vent gases and heat away from the pad surface, which keeps your brakes from fading under heavy use. This also helps to keep the rotor surface cleaner, leading to more consistent stopping power. The center hat is made from anodized aluminum, which is lightweight and corrosion-resistant. This two-piece design also allows for thermal expansion without stressing the rotor, which can help prevent cracking over time.

When installing these, you'll be reusing your existing brake calipers and pads. The primary job is to replace the rotor ring itself. Make sure to follow the manufacturer's instructions for proper torque specifications when reassembling. These rings are a direct replacement for the factory rear rotor rings, so installation should be straightforward for someone familiar with brake jobs.
