GiroDisc 14-20 BMW M2/M3/M4 (F8X w/Red/Silver/Gold Calipers Incl CCM) 400mm Slotted Front Rotors

If you're pushing your 2014-2020 BMW M2, M3, or M4 (F8X chassis) hard on the track or just demand the best from your street car's braking system, upgrading your front rotors is a smart move. These 400mm slotted rotors from GiroDisc are built to handle the intense heat generated during spirited driving and track use, helping to maintain consistent stopping power when you need it most. They are designed to work with factory red, silver, or gold calipers, and are compatible with cars that came with Carbon Ceramic Matrix (CCM) brakes from the factory.

GiroDisc rotors feature a two-piece construction. The rotor ring itself is made from a high-carbon iron alloy that's known for its durability and ability to withstand high temperatures without warping. This ring is then mounted to a CNC-machined, anodized aluminum hat. This design offers several benefits: it allows for thermal expansion of the rotor ring without stressing the mounting surface, it reduces overall weight compared to a one-piece rotor, and the aluminum hat is corrosion-resistant. The slots machined into the rotor face are not just for looks; they help to vent gases and heat away from the braking surface, which keeps the pads from glazing and improves wet-weather performance. This particular set is 400mm in diameter, matching the original equipment size for many performance BMW models.

When installing these rotors, you'll be replacing your factory front rotors. The two-piece design means the hat is already attached to the rotor ring, making installation straightforward. You'll want to ensure your brake pads are also in good condition, as new rotors perform best with new pads. These rotors are a direct replacement for the factory units, meaning they fit right onto your existing brake system without modification, assuming your calipers are the factory red, silver, or gold type, or if your car originally came with CCM brakes.
