B7 A4 s-line sway bars

[JGreen76]

Does anyone know the diameter of the B7 A4 s-line sway bars, front/back?

I am not sure how much of an upgrade aftermarket ones will be..

I keep seeing 32Fr and 20rear, but I think the rear is already 20mm with the s-line package...

Can anyone through me some knowledge?

Thanks

...or if the tubular oem ones are not as ridgid as the solid aftermarket ones..


Thanks.

Could use the info
