Whats wrong with 15" wheels? There are a lot out there that fit our cars, I dont know if you guys have seen my Enkei wheels, I got these wheels at my local junk yard and paid about 20 bucks for each 15x7 with zero offset and they look great on Celicas, and every time I'm the j/y i see more of them on 280's and other RWD cars, even guys driving Hondas and other riced out cars with 17" or even 18" wheels stop and tell me that my car looks good from top to bottom, cause all its parts look like they belong, I dont know if you guys have seen how our cars look with new modern wheels(import wheels) they suck! Looks totally out of place, the only other wheels that look good on our cars are Centerline Coronas, these things are cool, a guy I know has this Coronas in his 84 GT-S coupe and they are 16x8 and they are not too expensive. :D
Nothing wrong w/ 15" wheels. Just that for a GT-S, which runs 225 width tires, the selection available in 15" sucks. 225/50-16 is a perfect +2 size, so the speedo stays accurate, and it looks killer.
Maybe on a GT w/ the narrower fenders, a 15" wheel still has good tire selection.
I have not seen the Centerline Corona, but I have Centerline Hammers, and have decided I'm *sick* of taking care of polished aluminum wheels. They water spot & hold onto brake dust stains like you wouldn't believe. Either have 'em clearcoated, or powdercoated. I don't like polished/chrome wheels, so I'd choose to have 'em powdercoated silver, maybe w/ color accents to match the body color...
Some current FWD-fit wheels can look good on our cars, you just have to choose straight or angular wheels rather than the swoopy curved stuff. Angular cars need angular or blocky wheels to look right (plus I don't wanna show off my wimpy looking brakes). I know Celica brakes are anything but wimpy, but a very open wheel makes the brakes look even smaller.
