My friend recently proposed a very reasonable sale pitch to me. He owns a 2001 bmw 325i he just got rims and wants to sell me his oem rims for $500 with new michelin pilot sport 2's now i would need a fittment piece for them as well. The 17"by 8". would that work? Another proposal came to me from my friend who has a 2004 wrx sti, the wheels are the bbs gold 17" by 7.5 im not possitive but pretty sure they have the same dimensions as the accord coupe v6 bolt patter. Not sure which tires are on them but they are high qaulity sport summer. would i also need to recalibrate my speedo? Also if i went with the bbs i could get them dipped black or gun mettel right? if so for about how much?
