Ken, viewing the attachment in full size shows the car has TT brakes. I'm guessing from the appearance that they're 18x10 +45ish in the rear and 18x9 +40ish up front.
Blitz Type 03's are insanely desirable in the 'hellaflush' scene these days. I recently saw a pair -as in, two- 18x9 +22 Blitz Type 03's in much worse condition selling for almost $2000 for the pair. Not sure if they sold at that price, but it got a lot of attention.
I can't speak exactly to a Supra-fitment set like yours, but I'd imagine your set would sell very fast on this forum in the $2500-3k range.
