There was quite a cost difference between the two kits (Urge and Sakebomb). Shaving the pads is an extra step. It might come down to which rotor diameter (282mm vs 314mm) and caliper piston diameter provide the best balance with the front setup.

Assuming cut down pads and shaved bracket...
Three of the kits in the post above use the OEM caliper.

From posted results here, it appears all of the kits deal with overheated rear rotors.

the Sakebomb rear rx8 caliper kit does not - it's meant to be used with the Sakebomb AP racing front setup
OR our more affordable Wilwood version, but uses the same pad shape and rotor size. We also offer a hybrid kit with AP floating 325mm rotors.

And... soon we'll have something cool for the standard front kits for people that are running kits made with smaller / lower torque front pistons or stock front calipers We've got some cool thins in the works

Thanks in advance,

Hey Jonn,
Currently, these are meant to be used with our rear rotors (2 piece) not stock RX8 rotors which are a different hub bore diameter and rotor offset. The rears are currently sized for either our AP Competition front kit, or Wilwood Track Day kit with larger pistons, for a total system increase in brake torque/output. We will have something coming in the near future to run standard stock rotors or low-torque / small piston front BBK's such as the stoptech... but these are suited (as is currently) for the AP Racing CP8350 found in our Competition 325mm or Essex 299mm BBK's (as they run large piston sizes), or our SBG Wilwood track day BBK with large piston option (325mm rotor as well).

Our rear kit does include a *directional curved vane* rotor which actually pumps air through it, unlike a straight vane rotor, and does not require any sort of pad shaving or anything... just pop in a set of RX8 pads and you're good to go. Hawk, Endless, Carbotech, and many other brands make a pad for the RX8 caliper as it's very common.

I also run the Urge kit. The trick is to not file, it is to clamp an electric palm sander in a vice and hold the pad on it. Takes a few minutes per pad.
