it all depends on your taste... 1-piece, 2-piece, 3-piece... they all look fine... personally, i like most wheels with the fat lip, especially on the supra.
blitz, hre, volk, racing hart, they all look great. i haven't got any real preference.
Ive got 18" Volk TE-37's in white, on my red Supra and imho they look real good.
Some people say "hey your car looks like a race car". I say yep.
But big wheels look kinda goofy at stock hight, so plan on getting springs, like I had to.
