Rear sway bar... different ones in later cars? And what about the GT4 one?
i just bought a M3 GT4 rear sway bar, which has a 22mm diameter (and comes from eibach, by the way).
the street cars should have a 20mm one.
when i recently measured the one in my 2012 E92 it was 23mm?!
hmmm... did they change the diameter in later (LCI) models?
if so, is the GT4 one still stiffer due to thicker wall thickness or different material?
or does this mod not make sense in a 2012 M3?
