Girodisc A1-282 380mm Front Rotors for BMW G880/G82/G87 M2/M3/M4

Upgrade Your Stopping Power with GiroDisc A1-282 Rotors

Looking to enhance the braking performance of your 2021-2024 BMW M3, 2021-2024 BMW M4, or 2023-2024 BMW M2? The GiroDisc A1-282 2-piece rotors are designed as a direct replacement for your front rotors, specifically crafted for vehicles without carbon ceramic brakes. These rotors not only improve your stopping power but also contribute to a lighter, more responsive front end.

Why Choose GiroDisc A1-282?

The A1-282 rotors are engineered with a fully floating assembly that helps reduce unsprung weight and rotating mass at the front axle. This means better handling and improved performance, especially during hard stops. Each rotor ring is precision-machined from a proprietary high-carbon iron casting, ensuring durability and longevity under demanding conditions.

What sets these rotors apart is their innovative design featuring 72 curved vanes. These vanes act like a centrifugal pump, drawing air in through the hub to effectively cool the rotors, preventing brake fade during intense driving sessions. Plus, the 2-piece design allows you to reuse the aluminum hats when it's time to replace the rotor rings, making maintenance a breeze.

Built to Last

Manufactured in-house at GiroDisc's facility in Bellingham, WA, every component—hats, rotor rings, and drive pins—is crafted from high-quality, domestically sourced materials. The hats are made from 6061-T6 aluminum with a sleek black anodized finish, while the drive pins are constructed from a high-strength steel alloy and cadmium-plated for corrosion resistance. This attention to detail ensures that your rotors are not only performance-oriented but also built to withstand the test of time.
