- Sold as a pair (two discs) with fully floating, ultralight anodized 6061 billet aluminum hats and float-control/anti-rattle clips.
- AP Racing J Hook slot pattern: huge increase in airflow, cooling capacity and durability vs. OEM discs; consistent pad bite without the noise of drilled discs.
- Works with the OEM calipers – no modifications required (relocation spacers and studs are included where the OEM disc is a different diameter).
- PCCB-to-iron discs bolt on to the OEM PCCB calipers and wheels, run the standard iron-brake pad shape for your car, and have over twice the cooling vanes of the PCCB disc with replacement rings at a fraction of the cost.
- Designed for club racing, time trial, autocross and HPDE. Iron rings are replaceable, so you only buy the ring next time.
