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...

[eweu]

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.

[GaBoYnFla]

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

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

It was their 25mm rear bar for TT Quattros.

I think his point was that they would want to know, just in case anyone asked them. Also, they wouldn't want to advertise that it fits.

The bummer is that I'm not sure if they will make a bar that fits considering the low volume of cars.

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

Exactly.....I've know the Neuspeed folks a long time....they've always been good to me.

[kendoist4162]

Didn't Jason have a webisode about installing a RSW?? I imagine there are shots of the underside of his TTS.....

[DrDomm]

Here's some pics of the rear diff.









FWIW.

[DrDomm]

This is what happened to the bar...

[TheSandeman]

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?

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

[DrDomm]

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

What's that belt driving back there??

[996cab]

Well,
am glad you checked as many in the UK 'assume' TTS parts can be fitted on the TT-RS...it is the other way round iften i.e. TT-RS parts to fit TTS...so best stick to TT-RS specific item if for nothing else mainly due to the increased power and weight that these parts will have to deal with.

Also note that the rear ARB should be 22mm MAX else it will rub against other parts. We found H&R ARBs were best fit...there is a specific 24mm front and 22mm rears that you will need. I do not have the part numbers however I understand there is only one 24mm & 22mm for the TT-RS range.

AM not aware of any TT-RS owner who has fitted a different brand - I think H&R have got that particular business wrapped up and it does work very well.

[DrDomm]

That's not a belt. It's on the end of the input shaft going into the rear diff. Prolly some kind of balancer. It's metal, not rubber.

I forget what the stock RSB dimension is. Do you know? 22mm doesn't seem like such an upgrade. The Neuspeed bar was significantly bigger than stock.

I bet that with a different shape, a 25mm bar will fit.

The stock is 19mm front & 17mm rears if my memory serves me right.

The 24mm front / 22mm rear upgrade is large enough we have all found. Those who went larger came back to 24 / 22 due to rubbing issues.

I originally went 26mm front / 24mm rear and it rubbed so stuck to convention...!

Neuspeed told me they knew it would rub. They aren't sure if they will make an RS bar. I hope so.

Do they know what the reason is for the change in dimensions down there (what'd Audi change on the TT-RS)?

[Marty]

Hey DrDromm, did you solve your sway bar issues? I hear H&R makes a compatible bar, but I haven't found confirmed evidence of a well-fitting bar for the TT-RS.

[bigstu]

The model number for the 24mm front and 22mm rear H&R sway bar kit for the TT-RS is: 33220-2

I haven't really tried to get these yet, but was told that emailing export@h-r.com may help. Otherwise contact your normal H&R dealer and ask if they can get this part number. When you search, it only comes for overseas dealers.

[AppleChilli]

Subscribed. Very good flow of information here. Sorry to hear about your difficulties DrDomm.

[dogdrive]

I spoke to a H&R rep sometime last week.
He mentioned that they really don't have anything for thge RS at this moment.
He suspected it probably won't be until another 6 months from now when they do a press release on TT-RS suspension parts...

The question is, does the H&R rear bar for the regular Mk2 TT fit the TT-RS (since it has a different Haldex shape).

I'm ok I actually sold that bar to someone here. I was hoping Neuspeed would just modify the bar they sell, so that it will fit TT/TTS/TTRS.

[DesertTTRS]

Shox.com supplied the H&R sways to me!

[bigstu]

Did you buy H&R model number 33220-2 from shox.com?

[DesertTTRS]

includes the 24mm frt and 22 mm rear. Both are 2 hole adjustable. Going on my TT RS with H&R lowering springs P/N 29102-2 - .7 inch drop.Also have the adjustable drop links from 034 Motorsport. These will allow the install w/o any preload on the rear bar.I you preload the rear bar your car will be bouncy!
