Sure thing. The CP5040 was part of AP's Pro5000 line of conventional calipers. AP has moved away from the conventional caliper designs for the most part, and they've discontinued the CP5040 caliper around which this brake kit was based. The Pro5000 line has been replaced with the Pro5000
R line, which leverage the
Radi-CAL design. We no longer have access to the CP5040 caliper, so we can no longer produce the kit. There wasn't a whole lot more behind the move than that.
Our replacement kit for the CP5040/340mm kit is even more awesome:

It uses the same disc and same piston sizes, except it's mated to a Radi-CAL rather than a conventional caliper. That means it's lighter, stiffer, flows more air, etc. There is no downside to the new kit vs. the old kit, except that it is slightly more expensive. The CP9449 kit can be mated to any of our front kits, conventional or Radi-CAL, so there's no worry about compatibility. In other words, if you had our old CP5060/355mm kit on the front of your car, you can add the CP9449 Radi-CAL rear kit without any negative impact on brake bias, etc.
Please let me know what other questions you have. Thanks!
