Sold as a pair — one left, one right, matched. Price is for the pair.
F87 M2 / F80 M3 / F82 M4 front rotors — 380 × 30 mm, sold as a pair.
One disc, three cars. The 380 × 30 mm front rotor is shared across the F87 M2, F80 M3 and F82 M4 — which is exactly why buying the wrong one is easy. The M2 also runs a 400 × 36 mm front disc on some builds, and the G-series cars moved to 380 × 36 mm: same diameter, different thickness.
G3500 high-carbon ring, 6061-T6 aluminium hat, stainless floating hardware. 62.4 mm total height, 79 mm centre bore, 5 bolt holes — the F8x hub pattern.
Three numbers identify it: 380 mm diameter, 30 mm thickness, 62.4 mm height. The M2's 400 mm disc is obvious; the G80's 380 × 36 mm is the one that catches people, because the diameter is right and the thickness is not.
OE reference 34112284809 / 34112284810 · Minimum thickness 28.0 mm · Bolt holes 5
▸ Fitment check
F87 M2, F80 M3 and F82 M4 front, 380 × 30 mm — OE 34112284809 and 34112284810. Not the 400 × 36 mm M2 disc and not the 380 × 36 mm G-series disc.
▸ Fixed or full-floating — which one?
With three cars on one disc we see both — Fixed for road cars, Full-floating for cars that see track time. The low-speed rattle that comes with Full-floating is the ring moving, not a fault.
▸ Pads, bedding and ring replacement
On a shared-fitment disc, pad choice matters more than usual — a pad that runs hot on an M4 will do the same on an M3. Bed in with 6–8 moderate stops from 80 km/h.
▸ Lead time
Built to order. Production takes 10–12 days. Left and right are matched and marked before packing. Transit time depends on destination and service — we confirm shipping and delivery dates by email before you pay.
