Brake pads are not included. Racing pads are a personal choice, so Essex leaves them out of the kit price. The AP Racing Pro5000R calipers use industry-standard pad shapes stocked by every major pad manufacturer (Ferodo, Pagid, PFC, Raybestos, Endless, Hawk and more). Ask us to add a set at a bundled price.
Spare 380x32mm iron disc rings: 13.05.10048 (RH) / 13.05.10049 (LH) with 12-bolt hardware kits – ask us. Spare 365mm iron disc rings: CP5775-214GA/215GA (10-bolt) – ask us.
Caliper finish. Standard kits use AP Racing's hard anodized finish. ENP kits use the same caliper with a jewel-like Electroless Nickel Plated finish that is exceptionally durable, resists brake dust staining and is easy to clean.
