Man this is a great forum.. I never expected such fast replies. Yeah, I know 10mm isn't much, but I'm still trying to make it look kind of factory. Maybe I will go for 15mm. The reason why I thought 10mm initially is because OEM 21" rims come with 275/315 mm tire widths (10mm wider than mine) and I notice a significant different.. or maybe I'm just biased b/c they are 21's??

Thanks again guys,
Neil
