hey hey..yer man, no chance fitting rear bar.. but in saying that when you say "Dimensions" there is only an 1inch difference in the 2dr & 4dr's and that is in the boot of the car lol its an inch ay..and the wheel bases n shit are all the same too.. good luck.. iv got a bn sports front & rear bar.. and Uras side skirts.. love em fit nice too.. and btw when putting your rear bar on.. USE sikaflex (silicon) it on where it site near the wheel arches so it fits & sits nice, because it will look silly and be very weak..its worth the time trust me lol..
