15" Cragars SS! Look for them at swap meets and craigslist. I found mine at Good Guys in Pleasanton CA. 100 bucks with BFG T/A's that still had 5/32 of an inch. They are not perfect but good for a daily driver. Maybe you'll have such luck at a swap meet.
Year One makes some killer rims. Realistically performance tires are phasing out of the 15" rims. 17" rims have more tire choices. But I'm a huge fan of 15's.
Call up your local America's Tire or Discount Tire. And they will test fit your wheels before you buy. But you have to ask nicely.
