During our US press launch drive of the 2012 3 Series (F30) we took the opportunity to meet with an E90POST member (SharkH8R) who is local to the Monterey area and owner of an E90 325i (on lowered suspension). We had the chance to photograph the F30 and E90 in various angles for a great comparison of the styling and visual differences.
Here is how F30′s physical dimension compares to a factory E90:
0.31 inches (8 mm) taller
3.66 inches (93 mm) longer body
1.96 inches (50 mm) longer wheelbase
1.45 inches (37 mm) wider track [front]
1.85 inches (47 mm) wider track [rear]
