To summarize, PSCs last considerably longer than the PS2s in terms of not getting greasy. It would take only about 10-12 minutes of hard driving for PS2s to get all soft. PSCs pretty much lasted 30 mins or so, but got somewhat greasy after that as well. Also, I was a little under a second faster I think, but it is hard to say exactly. You definitely feel them biting harder on slow speed tight corners.

I was actually looking for a set of 18" wheels with the proper offsets that I could mount R compound tires on, and could not find any except for what Turner had, which was way too expensive. My search back then was documented here:

I will most likely start out with the PSCs next season, and once we have some good 18" wheel alternatives for the E9X M3, switch to a track setup then.

I am not sure if I should go with 18x9.5 with 275/35, or 18x10 with 275/35 or 285/30 all around. The turner car had 18x10 with 275/35 had all around. I think 25mm offset should clear in either case, but I'd like to know for sure.
Lucid, I checked your other posts and didn't see - Did you go with PSC+ or straight PSC? If you went straight PSC, what sizes did you get?
