CP8350, CP8250, CP8241
The range of four piston calipers we use in our AP Racing by Essex Brake Kits all have the same basic pad shape, however, the pads come in different radial depths / heights (D42-D43 or D50) depending on the disc they're being run on. As such, please be sure to carefully select the pads with the correct radial depth for your specific brake kit! Some general guidelines are below, but it's always a good idea to run a year/make/model search at the top of this page and verify the exact kit you have on your car. When viewing that brake kit, if you click the 'spares and accessories' or the 'technical specifications' tab you'll be able to see the proper radial depth of the discs and pads in your brake kit. We have tried to make this as clear as possible in as many places as possible on our website, and Essex cannot be held responsible if you purchase the incorrect pads for your calipers.
General Guidelines for Radial Depth:
- If your kit uses a 325x32mm Disc, choose D50= Ferodo FRP3116
- If your kit uses a 299x32mm Disc, choose D42 or D43= Ferodo FRP3097
- If your kit uses a 310mm or 338mm Disc, choose D42 or D43= Ferodo FRP3097
More on Radial Depth
The radial depth of the pad friction material is the height of the friction puck from top to bottom. If you run a pad with too small of a radial depth on your discs, you will be leaving a small unswept 'ring' around the disc near the attachment points to the hat (the pad will not hang low enough 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. Conversely, if you run a pad with too large of a radial depth, it will hang down too far in the caliper and potentially make contact with the disc hat.

In addition to podiums, AP Radi-CALs also help climb hills!
"I started out with the best, AP Racing, and haven't looked back."
"Without knockback, I am able to stay on the throttle longer and brake later, with much more confidence. It's made me faster."
