So, would I be OK in the area of:
Front 8" wide rim with 4.75" BS
Rear 9.5" wide rim with 5.5" BS

Rears are tight both inner and outer. I was getting a little contact with hard cornering loads with urethane from spring bushings and new OEM rubber rear bushings. Just installed urethane rears and I'm guessing the contact won't be an issue as they are much more rigid. My wheel opening to ground measurements are 24.25" front 25" rear. The rear inner lips have not been rolled, I had to massage a couple high spots on the inner sheet metal. That said all these car vary to a certain degree.

If you are looking at wheels that list an offset, you are looking for +6mm to be dead center in the wheel well.
A 245/40/18 is about as big as you can go up front, and you still may have some rubbing issues. 275/40/18 is about as big as you go in the rear without tubs. Obviously each car is different, and GM tolerances were questionable back in the day. Some cars seem to get away with slightly bigger, and some have had issues with slightly smaller.

OK, so....from what I've gathered so far...
If I keep my eye out for 18x8 w/4.75" BS for the front I should be ok and (I hate these metric tire sizes) I should get maybe the next size smaller (width) tire than 245/40/18 ?
For the back I should be looking for 18x9.5 w/5.5 "BS and maybe look for the next size smaller than 275/40/18?
I'll have to do some more research and relearn how to decipher the tire sizes again (it's been a while since I speced out anything). Then I'll see what I can come up with. I do have a 4.10 rear and probably really should have a 3.90 so if I go a bit larger in diameter in the back I may have to go a bit narrower.

Looks like their SQL server is screwing up though...
Code:

select * from products p inner join products_description pd on p.products_id = pd.products_id left join products_specs_wheels_new psw on p.products_id = psw.products_id where psw.products_specs_diameter = 18 and psw.products_id = 1968 and ( psw.products_specs_bolt_pattern = '5x120.7' or psw.products_specs_bolt_pattern2 = '5x120.7' or psw.products_specs_bolt_pattern3 = '5x120.7' ) and ( psw.products_specs_width >= '8' and psw.products_specs_width <= '9.5' ) and ( psw.products_specs_offset >= 6 and psw.products_specs_offset <= 0 ) and pd.language_id = 1 order by psw.products_specs_diameter, psw.products_specs_width, psw.products_specs_bolt_pattern, psw.products_specs_bolt_pattern2, psw.products_specs_offset ASC
hmmm.... Are they a reputable dealer?
