I have an extra set of 18x8.5 wheels (in addition to the 19x8.5 19x9 which are on the car now).

I can't use the 18x8.5 for autocross, and stay in street class (width's must be the same).
The width i less than I would want for 'stickier tires' for track use.

I've seen an number of 370Z folks use non-staggered wheels for their Z on the track, and they rotate. But, I've not seen anyone use only 8.5 inch width, always wider.

I'd really like a set of wheels suitable for track, I think I want a set of 18x9 (255/35 front) and 18x10.5 (285/30 rear). --- but I don't want to pay $1300+ for a set of wheels I'll only use at the track. I haven't seen any forsale opportunities for those sizes in the classified for a more 'economical price'.

Has anyone tried using 'thin' wheels for track purposes? Was it a pointless gesture? [tried to ask on370z site, but just can't get my account there 'validated', its like the admin -died- and the forum is just running itself with the people who already have an account)

IF you're not worried about knockoffs, you can get these in a 18x9.5 +30/35 and 18x10.5 +22 (would be real aggressive for a 285 though) for under $800

And a list of 18x10.5s (so they should have 8.5to 9.5s in most of them too)

lol, sorry, been busy I guess
These are available in a 10.5 +40 but since they are a dish wheel they may have BBK clearance issues, but would allow you to run 285s and a 18x8.5 +38

Here's one more, again brake clearance is always a concern w/ cheaper cast wheels since the thicker spokes & barrels take up more room.

The sedan S wheels with DOT legal race rubber would be a viable option. The extra traction more than makes up for the slightly narrower width. The taller sidewall won't be all that noticeable.

Coupe? or Sedan?

And what's your class restrictions?

If you're in a coupe, try to find two sets of 370Z rear sport wheels. You can typically find them used, and they're the perfect width/offset (19x10 +30) for a 285 (the max tire width for the class that I run in down here).

Your class restrictions may limit the type of tire you can have (i.e., no R comps, need to be 200+ treadwear, etc), so you'd be limited to like a 245 width tire. While that's not terrible, our cars like more tire not only for grip, but heat and wear management. A wider tire has more mass and therefore can take way more heat before they overheat.
