I just want to verify if anyone knows, does the rx8 have a diagonal split brake system? I removed a line on the master cylinder and slightly depressed the brake pedal to test which was front / rear and it seems a front wheel and a rear wheel seem to drag, while the other front wheel spun freely. I'm looking install a hydraulic ebrake for track, but it seems like it may not be possible with the abs module.. or at least keeping the 4 channel abs. Anyone know?

 

cross split brake systems are a fairly common option.
http://www.obpltd.com/ has both good hydraulic brake systems and pedal boxes to help with your needs.
Removing the brake booster and abs is a very hardcore mod though, track use only.

What's the need for the Ebrake on the track though?
