, i checked the springs codes and i found the front are C3 and the rear are C2, i also checked my friends 320s and they have the same springs but there height is completly different is this due to the high pressure of the bilsteins? or my front springs are wornout and cant hold the new shocks??
i also heard that people use the zsp and msport springs on the standard suspension but iam a little worried about the life span of my new shocks , and the only aftermarket springs i found was the koni sport springs that drops 30mm fornt and rear.
Just going from the limited information here is what I am thinking. In the US, these shocks (Bilstein B4) are sold as "Bilstein Touring Class" shocks. They have 2 different model numbers for fitting both sport and non-sport oem springs. I wonder if you ended up buying the shocks for the sport suspension that were designed for the shorter sport springs, then installed your non-sport springs, hence the increased height. The other potential could be new (thicker) rubber spring pads placed on the perches.
