I'm looking to get another set of wheels to better fit my track tires, and trying to decide between 17" or 18" wheels.

I'm currently running 225/45/17 square on the stock 264s, but I'd like to go to something wider wheel-wise, even if the tire stays the same. Other setup is M-sport springs and -2.0* camber from Dinan plates and M3 control arms. My last track day at NJMP I found some rub marks on the spring perch of my strut, which I haven't seen from past experience at Watkins; I'm thinking the loads were higher and the tire deformed more.

I was originally thinking APEX ARC-8s in 17x8.5 ET40, with 235s, but it seems like the tire selection is not great. 245 has better selection, but I'm not sure of the fitment.

The other option would be APEX EC7 in 18x8.5 ET40. The tire selection is again better (and in some cases, cheaper even), aesthetics are a little better I guess, but the wheels and tires will probably be heavier, which I'd like to avoid.

Any thoughts from the people who track their 128s?
