does anyone knows the dimesions of the front and rear swaybars on 1991 carrera c2 european version

 

My 1990 is 20 mm at the front and 21 mm at the rear. According to PET, a 1991 or later car has 20 mm at both ends.

This of course presumes no changes have been made or that your car does not have a bigger front bar (22 mm) that was available as the M030 option.

To make sure that I had what I was supposed to have before changing the bushes, I measured the diameter of the bars
