I am running on stock BBS WE rims (16in) with Eagle RS-A tires. I am unhappy with the tire and will change brands when they wear out. When they wear out, should I spring and go for a set of Rondell Cross Spoke rims sized at 8x17et35. The Rondells are sized for E46 BMWs. The wheel is at http://www.bekkers.com/details.php3?RondellCrossSpokeforBMW I need to know if the offset is correct or will I have to resort to spacers. If the complete set exceeds the resale value of my BBS (~$1200, 4X$300) The swap is unlikely. Also how much lower will my car sit with stock suspension with 45-series tires on 17in rims? Oh yeah and if anyone has the Rondell rims, please share pics.
