GiroDisc 14-20 BMW M2/M3/M4 (F8X w/Blue Calipers) 368mm Slotted Rear Rotors

What you get with this GiroDisc order are a pair of 368mm slotted rear rotors specifically made for the 2014-2020 BMW M2, M3, and M4 models equipped with the factory blue calipers. These aren't just standard replacements; they're a well-built upgrade designed to handle more demanding driving conditions and help your braking system perform at its best.

GiroDisc rotors are known for their robust construction. They feature a two-piece design, which is a notable improvement over many single-piece rotors. The rotor itself is made from a high-carbon iron alloy that's formulated for excellent thermal stability, meaning it can withstand the heat generated during hard braking without warping. The slots machined into the rotor surface are carefully designed to help vent gases and heat away from the pad surface. This keeps your brakes cooler and more consistent, especially during repeated stops or track use. The two-piece construction also allows for thermal expansion and contraction of the rotor ring without stressing the mounting hat, which can help prevent cracking over time. The hat is typically made from aircraft-grade aluminum, reducing unsprung weight and adding to the overall durability of the assembly.

When you're looking to get the most out of your BMW's braking system, especially if you push it hard on the street or track, these GiroDisc rotors are a solid option. They are designed to be a direct replacement for your factory rear rotors, making installation straightforward for someone familiar with brake jobs. You'll notice improved pedal feel and more consistent stopping power, even under heavy load.
