We're talking a 40-or 35 series instead of a 35 or 30 series for aspect ratio, it's not as if the 17's are balloon tires, and a little extra sidewall in the rear doesn't hurt for forward bite either. A 275 R888, for instance, is $51 *per tire* cheaper in 275/40-17 vs. 275/35-18. And there are a bunch more options in wide 17's in the semi-slicks like DOT Hoosiers that still run in the 25-26" diameter range that this car needs, and they're once again $25+ cheaper per tire than the 18" sizes

There is plenty of room for a 315/35-17 in the rear, though I'm not sure if the offset on the ET27 17x10.5's will get the job done. Only one way to find out...
315/35/17 was exactly what I was considering in the back...NT01s to be exact, though I've been told that they run wide for the size, so that might not be the best idea. 295/35 Ecsta XS would be a good fit as well.

My main driver for using 17s is the cost. I don't care what my track set-up looks like as long as it is strong and reasonably inexpensive. 17x10/10.5 F/R certainly fits the bill.
