Autocross tire fitting assistance

I'm thinking trying to go big with tires sizes this autocross season and am looking for fitment confirmation. I'd like to run Nankang AR-1s but the rear size may be a bit problematic.

My Boxster is a stock setup with

front:
-2.2deg camber,
8.5" OZ's, ET53 (may push out with 3 or 5mm spacers)
255/35/18

rear:
-2.5deg camber,
10" OZ's ET40
295/30/18

I'm not worried about the fronts but am a bit with 295s.

Anyone had luck with something similar?
