I forgot to mention that I already ordered a set of Apex SM-10RS wheels in Anthracite, because they were on sale
.
18x10 ET25. I'm planning to use CR-S tires on them. Most likely 275/35R18 or 275/40R18s. CR-S's are fantastic. They have a very stiff sidewall which improve steering feel and they are a bit wider than they claim, the 275s wear more like 285s and I don't want any fender rub so that should do the trick.
I've also tracked my M4 CS quite a few times with CR-S's and they are extremely capable. Few months back I set a lap record at a local track with them:
