I'm looking to upgrade my front and rear sway bars in my 01
A4 1.8TQM.

I was wondering if the sway bars on an 01 S4 would be a good upgrade?

I've heard that sport edition A4's have beefy front sway bars but I'm not sure about the rear.

My question is....what are the size differences between the A4 SB and the S4SB?

Any help would be greatly appreciated!

Thanks in advance!
