18" WHEELS
Anyone have advice on using 18 wheels all around. Any interference problems, over/understeer, etc?

I have 18's on all four corners and there is no problem as long as you stay wiithin the stock overall diameter. Are you planning on doing this with stock wheels or aftermarket?
I traded my 17's for a set of stock 18X9.5 and put them on the front with a Michelin 265. Of course i ditched the runflats in the rear also and went with a 295. Now i have graduated to 275's and 335's!
Bottom line: No issues.

I've got the stock painted wheels that I really don't like and want to replace. One option is to use 18" all around or go to 18 front 19 rear but I 'm not sure what 19" street tires are available.

You should have no problems with rubbing and your handling should be OK.

18x10.5 f with 275/35 and 18x11 r with 335 /30 for street
18x11 f with 25.5 x 11.5 x 18 and 18x 12 r with 25.5 x 11.5 x18 r for track
No problems what so ever.
Turning lock to lock at the extreem will rub the DRM brake ducts, but who turns that sharp? car feels sluggish at low speeds but great AT speed.
12" rims needed 3/8 spacer so I had to put on longer lug bolts.

the ride is not bad at all. I noticed almost an improvment 
ive got 265/35/18 in the front, and 295/35/18 in the back and they are great
they look really good. Since the rear sits higher on the vettes, and with the same size rim in the back, it almost "appears" smaller because of the more space over the tire to the body of the car. After i lowered mine so it is even in front and back it looks much better imho
good luck to ya
