Dave, Its the extra grip that makes the difference. On a turn like riverside it can provide the confidence inspiring traction needed to go an extra 5+mph faster, not to mention the extra braking advantage.
Keep in mind that its the wider tread width my 18s support that provides the advantage. If I had 9 x 17 and 10 x 17 wheels I could run the same sized dunlops in 17". Dunlop makes them, they are just very hard to come by.

Ok, cool.
That was exactly what I was thinking/hoping.
FYI I tried 275's in the back and the car stuck like glue. It was no fun!
I also think that you need more power than stock to really take advantage of bigger wheels. Right?
PS you should be receiving something later.

Jason, If memory serves it was the 17" dunlops that gave you the fastest laps at Pahrump when we tried both during the day and it was the 18" dunlops that gave you 1:27.xs at WS while the 17s where slower. During OTC it became clear to me that its important to match the tire size used to the track being driven. But it also seemed to me that the 17s would only provide an advantage at 2 tracks, Pahrump and SOWS. I dont think i'm giving up too much by sticking with
the 18s on those tracks but i'm certain i would be giving up alot by running the 17s at tracks like BW, LS, SP or TH. The extra speed you can maintain with the 18s through high speed turns is very hard to make up for with the slight advantage the 17s have in the tighter technical areas of a track.

David, Turn 8 in Dave's car with my wing was a piece of cake on 17's or 18's. I tried going through turn 8 on the 18's with the wing trimmed flat for extra speed, and the experience was a bit sketchy; only did that once. Glad I didn't try it on the 17's. On 18's the car had noticeably more mechanical grip through Turn 5, but the 17's felt like they accelerated better through 6 and 7. The gearing change makes it deceptive, as I was seeing redline in 5th before braking for 9 on the 17's but never hit it on the 18's. In the end I was 2 seconds faster on the 18's, and it's hard to argue with that.
The "rear" 17x9 Volk will fit on the front of the S2K with a spacer. Not sure if a 17x10 would clear the control arms, but if it would and somebody could make a really lightweight one with the correct offset/caliper clearance, it might be a good way to go. Of course finding the right tires in 17" is always going to be a challenge...
U2-winner Scott Smith was running $70 take-off 235 Dunlops at all 4 corners for the duration of OTC. Don't recall if they were 17" or 18", but I'd take a 235 Dunlop slick over a 275 DOT-R any day...

In fact, it was designed that way on purpose because you can't run a spare on the rear of the car (it will destroy the diff) - so you need to be able to swap any wheel to any corner in case of a blowout.
