Looks like shims and rotors are 2 major factors to keep heat off the calipers. I haven't found any drop in 2-piece rotors. I started this thread but seems to be dead:

I think with shims, pads, better rotors, hi-temp fluid and some form of air ducting might work with oem calipers.

Bradford, Any chance you can make some simple measurements to see if a stoptech rotor can fit with oem calipers? I now the diameter is larger but that can be turned down. How do the offsets/thickness compare between the 2 rots? Thanks.
