B8.5 Anti roll Bar with sports diff

Hss anyone changed the ARB on a car with sports diff. I have found that Audi put a smaller 16mm ARB on the cars with sports diff. What was the thinking behind this and is just going to the 21mm that they fit on the none sports diff cars an upgrade.

Then the question is would the uprated ones be too much.

I see Eibach have stopped doing them now.

I ask as i am about to install Eibach springs.

Cheers

I have a S4 Avant, tbh i couldn't say. I went from stock to uprated springs, end links, drop links and front/back arbs in one go. Car vibrations are more enhanced as it's now more stiffer but for me my family only go in it once in a while so the handling/planted upgrade was worth trade off.

Interesting, I have an S4 avant with the sport diff and have the H&R arbs bookmarked, but at £400+ I am hesitant to pull the trigger.

The part number I listed above is 22.5mm they probably just assumed it would be sufficient since the sports diff is doing a lot of the work at the back.
