Gtr rolla

hi guys does anyone know what would be the best size wheels to fit on ke10 iam thinking of changing stud pattern to the ke30 pattern and buy some of those rota wheels off ebay .mini light copys? or something similar. but there only made in 15X8 +0 +10 or +20 offset would any of these fit or would i have to flare guards and would 15inch be to big and look gay? if anyones got pics and sizes that would be great to see.. and if any body knows if ke30 axles fit the ke10 diff?? cheers
