GiroDisc 2020+ BMW M3/M4 (G80/G82/G83 w/Carbon Ceramic Brakes) 2-Piece 380mm Slotted Rear Rotors

GiroDisc is well-known for making high-performance brake components, and these 2-piece slotted rear rotors are a prime example of their work. Designed specifically for the 2020 and newer BMW M3, M4, and M4 Convertible models (G80, G82, G83 chassis) that came equipped with factory carbon ceramic brakes, these rotors offer an improved braking experience for your high-performance German machine.

These aren't just simple replacements; they're a thoughtful upgrade. The 2-piece design features a floating hat made from aircraft-grade aluminum, which is anodized for durability. This hat connects to the rotor ring, which is made from a proprietary cast iron alloy. This construction helps to reduce unsprung weight compared to a traditional 1-piece rotor, and the floating design allows for thermal expansion without inducing stress into the rotor assembly. The rotor ring itself is fully slotted, a feature that helps to sweep away dust and gas that can build up between the pad and rotor surface. This slotting pattern is crucial for maintaining consistent braking performance, especially during spirited driving or track use, by ensuring the pads have a clean surface to bite into.

When you're looking to maintain or enhance the braking performance of your M3 or M4, especially if you're starting with the factory carbon ceramic setup, these GiroDisc rotors are a solid option. They are designed to work with your existing calipers and pads, making the installation process more straightforward. Remember to always refer to the manufacturer's installation instructions for proper fitment and any specific hardware requirements.
