The e21 wheels have an 18mm offset and the e30's have a 22mm offset (I think) . Thats like having a 4mm spacer. Old Bavauto springs, Bill Sport dampers, rear strut bar, 2.7 motor ("short" block) / was going to do "the build" but this was so easy and the car is very quick. AFM was retuned ( 5 clicks) for more fuel. The air dam is extended and brake ducts / aero underpan is complete - great for high speeds. This car came from the Capitol Hill Auction in 2007 from the "not running" section. The previous owner was a woman - so the car was in pretty good shape .
