What's in the box

  • One pair AP Racing Radi-CAL Pro5000R racing calipers (four-piston, part number as shown in the kit name)
  • One pair 380x32mm AP Racing CP5772, 72 vane, J Hook racing discs, with fully floating 6061 hard anodized aluminum hats and attachment hardware
  • Disc burnishing in Ferodo Racing pad compound included at no additional charge on GT-car kits (normally $150 per disc pair). If you are using a brake pad brand other than Ferodo and are interested in compatible disc burnishing, please contact Essex support prior to purchase.
  • One pair caliper mounting brackets and hardware
  • One pair Spiegler Stainless Steel Brake Lines with abrasion resistant coating
  • Detailed installation instructions

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.

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.
