TT RS Rear Sway Bar...

[DrDomm]

Well, I put the Neuspeed RSB from my TTS on today. I'll be taking it off tomorrow. The little bolts that attach the right half shaft to the differential make contact with the bar. I never would have thought there was a difference between the TTS and RS diff. I only noticed when I backed it out of the garage. Hits slightly under load. Grrr. Take a look...

Yikes. Glad you found out so quickly after installing.

Do you have any more pictures of the diff itself? I wonder what the differences are.

[joshsmith]

Interesting.. I mentioned this a while ago as my dealer told me there was some serious differences down there (can't remember the list)..

Definitely lucky you found sooner rather than later!!

We want more pics of your car Domm

[DrDomm]

I'm a terrible photographer. None of my pics look that good. All I have is a little point and shoot digital. I'll see what I can do.

Make sure the Neuspeed guys know....they pride themselves in quality and fit....What size was the original bar? Wonder what the "stiffness" difference is?

well if it wasnt listed under TTRS on their website, they have nothing to worry about nor are they liable for compatibility issues

regardless that sucks Domm

It was their 25mm rear bar for TT Quattros.

How about some under-body comparison pics of the differential area of the TTS and TT-RS for comparison?

I took some of the RS, but I don't have the TTS anymore.

Domm was rubbing against you're axel? I'm curious to know what are the differences other than the obvious btw the RS and the TT/TTS

If you look at the first photo, the torx screws that are protruding from the rear diff on the right side were hitting the bar when the suspension was compressed...on the ground. Those pics are with the car on jacks and the wheels hanging.

I think the difference is either the screws/bolts or just the dimensions of the equipment connecting the rear halfshafts to the differential. Just a small difference.

Maybe the RS has beefier half-shafts to deal with the extra torque?

It probably does. But I think this problem illustrated that the connection to the rear diff is beefed up.

ah i see... being that the RSB is of a tubular design, im assuming it wouldnt be a great idea to grind it down a bit for clearing the rear diff bolts.... now a solution

[Black BeauTTy]

This one has me interested. I found the upgraded RSB made a nice difference on the mkI, I suspect the same will be true on the RS.

[Marty]

I definitely felt a lot of understeer at the track that I assume could be reduced in exchange for a bit of stability with a stiffer RSB like this. Definitely interested, but I'll probably wait for a few Guinea pigs to test fit these bars first so there aren't any headaches.

H&R 22mm rear bar works great without any rubbing. Gonna post a writeup when I have the time.

Is that bar solid? I'm impressed this 034 bar is solid.

Back to preload and adjustable end links...my (limited) understanding is that preloading the bar will affect corner weights when setting up a "racecar". To set up the racecar suspension, you'll be adjusting ride heights. If you don't have "coilovers", you aren't going to adjust ride height on the TT RS.

So...the stock end links should be "close" to the right length to install a bar that is the same shape/size as the stock bar...to have whatever amount (hopefully negligible) of preload Audi thought was appropriate. Likewise, I'm assuming the Neuspeed endlinks would be fine also.

Endlinks really shouldn't make any difference for you unless you are trying to do precise corner balancing for a track-only car, or if the stock endlinks break with the stiffer bar.

[jibbed]

Just ordered it guys (also have the sway bar end links which I haven't yet fitted).

Will post a review after it arrives.

[Black BeauTTy]

Thanks. Will be anxious to hear your thoughts.
