The new 18x12s w/295/35 RE71RS worked really well! I was definitely faster, and within .3s of the winning AS Cayman which was driven by a past nat'l champ at a BMW club race yesterday. I ended up 5th overall PAX, but this race wasn't as competitive as local SCCA races. My car is pretty much stock besides alignment and wheel/tire setup, so not bad for the new .827 CAMC PAX index.
Here's a couple of pics of the bike rack turned wheel carrier...
