Front Rotor Rings

Included Front Bolt Kit

Rear Rotor Rings

HFM.Parts Replacement Rotor Rings & Bolt Kits are replacement outer rings for compatible HFM.Parts two-piece brake rotors. The existing compatible aluminium hats are retained.

Select Your Existing Rotor

Choose the exact HFM.Parts front rotor-ring version fitted to the vehicle, then select the bolt standard used by your existing hat. HFM states that older rotor hats use M6 x 1mm hardware while newer hats use M8 x 1.25mm shoulder bolts. The two standards are not interchangeable, so the existing hat hardware must be checked before ordering.
