The rear spring/strut travel of the E46/16 is approximately 17mm less than the 2wd version.
The reason for the reduced travel in the rear is to oppose any excessive body roll as a result
of the higher body profile.
The rear sway bar has been increased in diameter to 20mm (2wd standard: 18mm, sports
suspension: 19mm) to accommodate the additional weight.
