Hotchkis says 22829 won't fit. Just ignore that?

[bstaneland]

I have an 04 A4 quattro 3.0 cabrio. I am looking at the Hotchkis F&R S4 sway bar kit #22829. But Hotchkis says it doesn't fit my vehicle and I need to be buying kit #22823.
Do I just ignore what Hotchkis is saying and go with the S4 kit #22829?
Every thread I've read talks about installing the S4 kit, but none of those threads are specifically about the cabrio.

Almost everything about the cabrio is different. You are best sticking with their suggestion as standard S4 parts probably aren't going to fit right.

Hotchkis has H-sport sway kit, and RS4 one.
I think it's the same but the RS4 one uses a much bigger rear.

Then a grease for the bushings.

However, you have a cabrio.
What's common, is sedans and avants. Avants are sedans but with a taller trunk.

I thought I got lucky finding a cabrio S4, to grab the rear sway from it cheap.
Then upon closer inspection, I recall it looked really different shaped.

Wonder if ETKA reflects this with different PN's based on cabrio.
My point is this: I wonder if they're different.
I'd want to make sure before trusting an aftermarket site.

edit: actually, I don't know what's going on

Was hoping you guys with A4 that have installed this S4 away bay kit could chime in because Hotchkis says that this same kit (22829) is not supposed to fit your (or any) B6 A4 either.
But everyone that has installed this setup loves it, so obviously it does fit and works quite well.
Am I missing something here?
Why would Hotchkis say it doesn't fit?
Hoping someone on here with a cabrio has done this mod.
I'm calling Hotchkis once the sun comes up...

Well first, at least it's not a rush. It's an optional upgrade. Not a mandatory service item. FWIW. So, at least that could buy you some time to figure out what to do.

Second, I wonder why not. Because if it says "S4" - well, the B6 S4 is still built upon the B6 8E chassis.
It just has a big heavy V8 shoe-horned in the front. Otherwise I personally don't see what the difference would be.
Rear subframe should be the same. But while A4 uses heavy rear wheel bearing housings made of iron, S4 has a few pounds lighter/less unsprung weight because it's aluminum. Some people have retrofitted those parts.

"Everyone that installed this setup loves it" - which one? S4? Like I said, this is the first I hear of it. At least for me. I've heard of RS4, and H-sport.
And as for "loves it", if such opinion even exists, I take that with a grain of salt and have to see for myself. I think it would depend on what type of car it is, how it's driven and in what conditions, and what shape the other parts on it are in. Including springs.
But I've seen two sets pop up used at a discount before in the classifieds before. It's not common. Maybe it's not a bad idea.
There is also 034 rear sway. I'm not sure how they compare. And I think their rear, at least, might cost a bit less and come with spherical end-links. I'm not saying which to get, I don't even know.

I installed the 22829 (S4) kit on my A4 sedan. No issues.

edit: I ordered thru Amazon due to the best price I found. Do that and return if something doesn't fit.

Yeah, thanks for confirming. FWIW, I also just spoke with Hotchkis and they confirmed the 22829 will fit all the A4 B6/B7 variants. On their website it is coded so as to only show the specific model designation as a form of liability protection or something like that. Thanks again for your comment. Cheers.
