Girodisc BMW F80 F82 F83 F87 Front 400mm 2-Piece Brake Discs – Pair for M2 Competition, M3 and M4
Upgrade the front brakes on your BMW M2 Competition, BMW M3 F80 and BMW M4 F82 F83 with Girodisc 400 mm 2-piece floating slotted brake discs. This premium performance brake upgrade delivers stronger bite, faster heat dissipation and consistent pedal feel for track days and fast road driving. Made in the USA using proprietary cast iron rings and a lightweight 6061-T6 aluminium hat, these Girodisc front rotors reduce unsprung mass and improve cooling for repeatable, fade-resistant braking.
These Girodisc A1-220 front brake discs are a direct bolt-on replacement for the factory 400 x 36 mm front rotors, retaining your OEM calipers and pads while dramatically improving performance. The curved vane, vented design works like a centrifugal pump to pull cooling air through the rotor. Precision slots refresh the pad face and maintain friction under heavy use. Zinc-coated for corrosion resistance and long-lasting good looks.
