Audi 80Q B4 Sedan rear sway bar

[afterburner]

Hello! I want to replace my original small rear sway bar with something bigger. As far as I know I can use one from the RS2 Avanat, which is 16mm thick. Does the sway bar from an A4Q B5 fit also? They share similar rear suspension.

B4 and B5 sedan rear swaybars are the same size. You'll have to do the B4 RS2 or B5 RS4 RSB if you want to go bigger.
