Direct OEM Replacement. Race-Grade Upgrade. Built For The F87 M2 Competition.

Complete your F87 M2 Competition brake upgrade with the SPECWORKS 2-piece floating rear rotor — a direct OEM-size replacement engineered to outperform the factory one-piece disc in every measurable way. Lighter, cooler, and stronger, these rotors are built for owners who push their M2 hard on road, track, or both.

Direct bolt-on fitment — no caliper changes, no bracket changes, no compromises.

Pair with our SPECWORKS F87 M2 Competition Front Discs for a complete balanced brake upgrade.

🔥 ROTOR — SPECWORKS 2-PIECE SEMI FLOATING DISC

  • OEM-matched 380mm x 28mm rear disc dimensions
  • Two-piece Semi floating construction — iron rotor ring + aluminium hat
  • THERMACORE™ high-carbon iron alloy rotor ring for superior heat management
  • Optimised internal vane geometry for faster cooling
  • Floating bobbin design accommodates thermal expansion under extreme load
  • Hard-anodised aluminium hat — corrosion-proof, lightweight
  • Significant unsprung weight reduction vs OEM one-piece rotor
  • Reduced rotational mass = faster acceleration, sharper braking response

🎨 CUSTOMISATION OPTIONS

  • Rotor face pattern: J HOOK / Curved Slot / TY Slot
  • Hat colour: Black / Bronze
  • Hardware finish: Silver / Black

✅ WHY UPGRADE FROM OEM

  • Lighter — reduces unsprung and rotational mass vs factory disc
  • Cooler — two-piece design dissipates heat significantly faster
  • Stronger — race-grade iron alloy resists warping and cracking
  • Serviceable — replace the ring only when worn, keep the hat
  • Better pedal feel — no fade, no vibration, consistent bite lap after lap
  • Direct fitment — uses OEM calipers, OEM pads, OEM brake lines

  • 2 x SPECWORKS 2-piece floating rear rotors (L/R handed)
  • 2 x Hard-anodised aluminium hats (pre-assembled)
