What is included in the Kit:

  • One pair 325x32mm AP Racing CP3908, 70 vane, J Hook racing discs, with fully floating 6061 hard anodized aluminum hats, and attachment hardware
  • 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 with our system. Racing brake pads are a highly personal choice. Many manufacturers include a set of inexpensive, low quality pads with their brake kits. Rather than artificially inflating the price of our system with a set of pads you probably don't want anyway, we've decided to remove the cost from our system and allow our customers to choose the pads that best suit their needs/wants. When purchasing our kit, you are able to choose one set of front pads at a substantial discount vs. the retail price. Please use the drop-down menu to select your pads.

Below are the pad compounds that Essex offers for our CP8350/325mm disc combination. Please note that the pad shape we use in our caliper is available in a variety of radial depths (heights) from different manufacturers. When combined with the CP3908 325x32mm disc, Essex recommends the 50mm radial depth version. Other common radial depths in this pad shape are 43mm and 39mm. Those radial depths will fit into our caliper, but you will be leaving an unswept 'ring' around the disc near the attachment points to the hat (the pad will not hang as low in the caliper). Leaving a portion of the disc face unswept can create a temperature differential across the face of the disc, and doing so could lead to premature disc cracking. That said, we have not run into such a problem with our kits in the field.

Below each manufacturer listed below, the pad compounds are ranked from most aggressive to least aggressive.

Pad Cross Reference
Again, please keep in mind that there are many other compounds available on the market from other manufacturers. Since we do not offer many of the brands listed below, Essex cannot guarantee the fitment of these pads in the AP Racing CP8350 caliper. Based on our research however, we believe that these are the appropriate cross references for the basic shape. However, you should verify with either the manufacturer or your installer prior to purchasing any of them.
