I'm looking into adding some anti-roll bars to the stasis street coilover kit. Does anybody have a preference in what brand to buy? I know LLTek makes both front and rear (and i believe the rear is adjustable), and they also sell them as a full kit. On the other hand, Eibach makes a front sway bar and neuspeed makes a rear, and my original plan was to put those on. If anyone has any of those installed, I would really appreciate any input you have. Thanks!

The S4 is best suited to a 19mm rear sway bar. Nothing more is necessary after adding a CO. The Neuspeed is the most popular and is adjustable.

 

19mm is all that is needed for the S4? What is the stock size of the rear sway? My TL-S comes stock with 19 rear, and the aftermarket bars start at 22mm as a matter of fact Neuspeed made one *now discontiuned* that was 25mm for my car. Do any aftermarket companies make a bar bigger then 19mm for the S4 or is it really overkill on the smaller car?

 

Can't say I have seen any sane A4/S4 driver do anything more than 19mm. I suppose you could go bigger, but what's the point. If the shoe fits, why fix it?

 

The puprose of going with the "larger" 19mm rear is to offset the understeer of the S4. The Neuspeed bar does this very well. It is not necessary to go bigger. Bigger is not better in the case of suspension. You need to strike the proper balance.
