I've been running my track set up - ARC8 18x8.5/255/40/18 MPSS - for 2 weeks on the street now since missing COTA due to pads that didn't fit and have loved the feel.
So much less understeer and tons more front grip, car used to really push badly in corners. Still does a little, but square is so much better than staggered.
Also zero rubbing, even on high speed corners on SH45 with a lot of bumps and road undulations. My only gripe is the TPMS light being on all the time, but have gotten used to it
