Ultra Racing Strut Brace installed

[xpoweruk]

For those of you wanting to fit the S4 version I say Do It :)

I'm in the UK so no AK brace/034 brace available & I don't have the CR-15 either

Fitted & now wearing a beaming smile

Steering feel/response/turn in is now so much more precise,the difference is like night & day.

Well worth every penny IMO,


A couple of install notes.

as you can see (below) I have used a couple of cable ties to hold 1 hose out of the way to help prevent any rubbing.

Other than that it goes straight in

[ChobeG]

did you have to drill any holes?... my S4 doesn't have any bolts or holes on either side of the shock tower... I looked at this bar last year but definitely no holes for the mounting bolts on my car..

[Danny2323]

I'm installing it this weekend. I'll have a review, but I already have the CR-15 and AK, so we'll see what kind of incremental change it makes.

If you either of you could please take pictures of the mounting bolt points that would be great... I can see two bolts on the top part of the tower on the first picture that i don't have pre-drilled holes for... unless it's only supposed to mount on the two bolts on the lower section of the towers... but would be good to see a close up

[xpoweruk]

The side closest in the pic has 2 threaded studs already in place on my S4.The farthest one is the jump start post (negative terminal)
Edit
I pinched a pic on google to show the UK drivers side mounting points

very nice !! 1) what is that revo plate ? hold the tubing from moving ? or it's an engine damper ?

2) any plan on going with the 2 other brace under the car ?

[silverf0x]

Sorry for the off-topic, but is that heatwrap REALLY making a difference?

[4wheelpilot]

Did this brace come with adequate installation instructions including torque #s for the bolts?
Did you need longer bolts?
Install time?
What changes did you feel...over rough roads, while cornering, during hard acceleration?

Nope. Its not insulating its reflecting. In the case of an engine bay you'd need to insulate from heat to be truly effective.

The revo plate is part of the revon intake,it holds the weight of the intake tube

i may do the other 2 in the future,but not immediately

Actually it does,since fitting the IATs on the P3Cars gauge take longer to rise when in traffic etc

No instructions where included,so no torque settings are provided.The 2 main anchor points are suspension bolts (1 each side) so torque for those points are as OE fittment
The other smaller nuts are just steadying the bar so I just nipped those up
No longer bolts where needed
Install time 10-20 mins
Turn in is much sharper & more precise,feedback from the road is much improved whilst cornering & inspires confidence.

[infinkc]

does the upper engine cover fit back on? or does the bar get in the way of it?

[Danny2323]

Bad news - I goofed up, and didn't check to see if I had the passenger-side upper studs. My 2014 S4 doesn't have them, but I went ahead and installed it without them. It's attached with only the lower two suspension bolts, and the VERY weak negative jumpstart post. I don't know how impactful it is that I'm missing the upper studs.

http://uploads.tapatalk-cdn.com/20160415/0545c6c13bc9f2331e3ca28d396081b3.jpg

http://uploads.tapatalk-cdn.com/20160415/3798fe8171944ca7a6a3c700c15ceb8b.jpg

I took it for a short test drive. I have the CR-15 and Alu Kreuz, and otherwise stock suspension (for now, but I have PSS10, sways, and moog end links waiting to go). The UR brace did make a change, but it was very subtle. It might be because of the missing upper studs, and it might be because my front end was already stiffened up significantly, but the improvement was barely noticeable. The steering feels ever so slightly heavier, and just a hair sharper, but barely. With all the stiffening, I feel every little crack in the road. Not too harsh, because the stock suspension eats up bumps, but there's more noticeable "thuds." It almost seems like there's a slight harmonic after hitting cracks, like I can feel the suspension rebound more.

To be honest, I'm not sure it's worth it if you already have the CR-15 and the AK, but only if you're B8.5. I can't say how much better it'd get if the same combo was performed on a B8, with the proper passenger side upper studs. Maybe it helps, I just don't know.

[silverf0x]

I don't have any bracing so far..

[1975audi]

subscribed.

[ChobeG]

my car is the same... mine is a 2015 and it doesn't have the two bolts at the top of the tower... So considering it's only held by the two lower suspension bolts and the bracket or mounting plates have all those bends, it makes me wonder if that would still allow for some flex.. It would reduce some no doubt but it doesn't appear solid enough at the mounting plates.. I guess the other option since i know how to weld, it would be to weld extra metal supports at the bends to form a rectangle for added rigidity.... just a thought... I rather weld on the bar than go opening holes or touching the car.

[waxxonMTL]

wow that suck for b8.5 :( glad you guys did the research :) Like mentionne before, I don't think the fact theres only a lower point holding the bar really ''stop the flex''. A strut bar has to be well fixed to do its job. Maybe we could pin point this thread to UR and they could develop another one ?

[xpoweruk]

It is quite possible that the smaller studs are of no real consequence TBH.
It is sold as a 2 point brace afterall.
I would say that because you already have all the other stiffening mods done that flex has already been reduced considerably.

For instance I imagine if you fitted the UR brace before the CR-15 it may well have felt so good already that the CR-15 had only a small impact


I don't have any bracing so far..

[cspcrx]

so do the B8 cars have more bolts that allow attachment than the B8.5s? It looks like from the two photos the B8 had 3 bolts on one side and 1 bolt and the ground stud on the other. Is this not the same on the B8.5

[xpoweruk]

Also it wouldn't take long to drill a hole pop a bolt through.

[14S4GWM]

Just get the cr-15 and call it a day.

[silverf0x]

Just get the cr-15 and call it a day.

Hmm I already bought that strut bar thinking it was fitting B8.5.. Will have to sell it back I guess..

[Danny2323]

Agreed to everything above. I definitely think having everything stiffened up beforehand has made the impact of the UR minimal. If you have a B8.5, and no bracing, then definitely, positively, start with the CR-15. Best bang for the buck. Also, I'm sure missing the upper bolts affects its ability to work right. It results in a pretty significant "lever arm," with the only attachment point being offset from being inline with the bar. Maybe triangulating the bracket would help, but I'm not going to mess with it.

[ChobeG]

i think if this bar was a little bit more reinforced at the mounting plates it may or it could potentially introduce a fraction more rigidity than the CR-15 due to the fact that it mounts directly onto the shock towers, which is where any chassis movement will mainly be generated.. whilst the CR15 sit behind the shock towers... anyway this is all hypothetically speaking as without any measuring devices we will never know.. having both if you have the cash definitely wouldn't hurt or even having one or the other will still provide some much needed rigidity at the front for all of us RHD guys that have been disadvantaged with no RHD versions of the Alu Kreuz or the 034 x-brace...

[silverf0x]

How does the driver side fits where the negative pole is? Does the pole needs to be removed first? And if so, is there any precaution that needs to be taken before removing the pole (like disconnect the positive pole has well?)

Bringing this Up. Received mine and tried fitting but I was wondering how did you got the brace to fit driver side with those hard (non flexible) pipes in the way? Did you had to pry them to fit the brace under? Any tips?

Also, which of the washers that came with the kit did you use and where?

It took a lot of maneuvering, and some slight paint scratching, but mine went in without bending the lines. It was a pain. I used a washer under the battery terminal post (re-tighten it with low torque - it's a weak bolt). I didn't use a washer for the two lower bolts, because the stock bolts are flanged.

[Works2shoot]

Why are you guys using "weak bolts," and making modifications etc for this mod On the 8.5s? The CR15 does the job - and it doesn't require putting stress on studs/bolts that can break. No judgement, just asking a question.

[S4'ed]

Because more stiff = more better......

Can you please post photos of your install...both strut towers?

So to confirm...this brace can be installed on the 8.5, correct?
How many bolts does this brace attach to on the right and left strut towers?
Does it attach securely enough to work well and not get loose over time?
Thanks

Post #25

Thanks for pointing this out...I was following thread and jumped over your post.
I just had the 034 solid rear sway with moog end links installed plus 034 trans insert and eurocode rear diff inserts.
The trans insert has pretty much eliminated the dsg drone and clunk when downshifting.
Can't believe Audi didn't design these into the S4 from the start.
Have been waiting to decide what to do about the front end. I'll wait for a group buy to get the alu kreuz and leave it at that.
Thanks again for sharing your experience Danny2323!

[silverf0x]

Thanks for the info.

I'll be doing the brace first and will get the CR-15 later (next week I guess) so I'll be able to review the brace alone....

[silverf0x]

So I installed the UltraRacing brace this week-end and installation was easier than previously expected. I didn't had to bend any of the hard line (see previous post) but it's a tight fit and definitely a paint scratcher.

I wasn't able to make it to the track so my first impressions are base on spirited driving.

0) It took me MORE time to remove all the packaging material than to install the bar.
1) Didn't change bodyroll significantly.
2) Turn in is slightly (VERY slightly) better.
3) I was afraid that, since B8.5 don't have the two additional bolts on the passenger shock tower, it would be less stable but I realize that these bolts wouldn't change anything since anchorage is more than enough at the lower position.
4) Paid 155$ CAD (with shipping) but was asked to pay an additional 36$ CAD at the door by FedEx (so that eBay 5$ shipping is pretty much a scam).

For a total of ~191$ CAD, my conclusion is that this bar is not worth the price. But now that it is installed, I don't think I'll go through the hassle of removing it (mainly because of paint scratch).
If it would've been around 100$ I could conclude otherwise but I would not suggest buying it unless you have a good deal on a used (undamaged) bar or, like OP, this is your only bracing solution.


*I must state, again, that this review is based on road driving as opposed to track driving.

I will update once I install the CR-15, to see if it makes an actual difference.

Really appreciate your real world experience with this brace.
I would have expected a more noticeable, and improved, feel with turn in.
Is there any improvement/less front end deflections, when going over uneven road surfaces?

Great that you'll be able to feel the difference the CR-15 brace makes soon.

[silverf0x]

Is there any improvement/less front end deflections, when going over uneven road surfaces?
Now that you mention it, I drove on very harsh roads this week-end and noticed that the car stays more flat when hitting a pothole with one wheel only.. It flexes less. Same goes for taking speedbumps with one wheel only.

I'm no expert but I guess it means that the suspension takes a bigger hit?

Based on your post and experience and factoring in price, in what order would you place the following for overall benefits to handling and ride ...
Alu Kreuz, CR-15 and Ultra Racing strut brace

[S4'ed]

I would say for the price, the best handling improvement are front and rear anti-roll bars, 2nd is CR-15 (or UltraRacing), and significantly in last place is the Alu Kreuz.

None of the chassis braces will significantly change the roll-angle of the car....if they do then you have a chassis made out of silly-putty......

[xpoweruk]

For me AK is not available as I'm in the UK
So IMO the below is what is needed

Rear ARB only ~(reducing understeer)
UR strut brace ~ Sharper turn in,better feed back, (becomes more evident if you drive harder)
wider front track than rear (reducing understeer)
Lower front ride height more than rear (reducing understeer)

Very interesting comment regarding the AK.
Many owners with the AK comment that it stabilizes the front end.
And some feel that it offers significant handling benefits.
What makes you think otherwise?

[S4'ed]

The factory front subframe looks pretty stout to me.......and the AK is an expensive item. A chassis brace (CR-15 or UltraRacing) at the top of the front structure, where there currently is much less factory cross bracing, is probably way-more rigidity improvement bang-for-the-buck. The AK certainly can't hurt, but I think there are better places to spend your handing improvement $s....

Any of these chassis braces can provide a subtle improvement, but a set of upgraded anti-roll bars provide a much more dramatic handing improvement.

does anyone fix up this rear lower bar before?

thanks

you had the cr15 installed ?

[lowjonathan]

you had the cr15 installed ?

nope, i didnt install cr15 yet.
i guess both work the same to stiffen the front

[u2nelson]

For me AK is not available as I'm in the UK
So IMO the below is what is needed

Rear ARB only ~(reducing understeer)
UR strut brace ~ Sharper turn in,better feed back, (becomes more evident if you drive harder)
wider front track than rear (reducing understeer)
Lower front ride height more than rear (reducing understeer)

FYI, I do make the CR-15 for RHD cars now, it drops right in. PM me for details.

Review update after installing the CR-15:

I wasn't sure, to be honest, if the CR-15 would live up to it's "hype" but man was I wrong. Count me in as another guy in the "totally-worth-it" club. I can't tell if it's the combination of both CR-15 and UltraRacing bar but it did wonders. I'm not planning on removing the strutbar so I guess I won't really know but all I can say is it makes the car flat and removes alot of bodyroll (can't imagine with sways!).
I had to re-install the CR-15 three times because I didn't look at the instructions properly [headbang] The good thing is I could install one with my eyes closed now LOL.

A chassis brace won't do anything for body roll........

[amz]

...where there currently is much less factory cross bracing...

Aren't the dual factory firewalls supposed to be the "factory cross bracing"? I don't think they do a superb job though, while looking at the B9 A4 in the dealers show room I noticed they have strut tower braces connecting to the inner-most firewall (closest to engine, furthest from driver.)

[S4'ed]

A big U shaped (open at the top) section of floppy sheetmetal does not make for a great cross brace........

[pachilla]

Factory lower suspension brace on S4 is much stronger than on A4,

so the difference AK makes on S4 is much less significant than on an A4.

This adds torsional stiffness to the body between the front and rear axles, its very common feature on factory convertible vehicles which does not have a roof structure, but I do not know of any user reviews on it.


AK and CR-15 can only help to stiffen up the rather flexy A4/A5 B8/B8.5 front end.

[OnEaNgRyBuNnY]

Anyone notice any downside to tightening up the front so substantially while doing little to nothing in the rear? I'm talking about guys running the AK, front and rear sways, this and/or a CR-15.

I think with the weight of the engine + the steering geometry components I would guess that the front has the greatest room for improvement. Just my 2¢.

[waxxonMTL]

UR also make front subframe bushing.. I'm tempting to try them, but it's been known that the bar fit better the B8 than the b8.5 so I'm hesitant to buy anything from them.

Came across this thread and decided to try the UR bars.
Not sure which bars help, but steering feel, response and turn in are more precise.

oh cool! B8 or B8.5 ? Good to know that other bars seems to fit also.

[xpoweruk]

Nice to see them fitted :)

BTW, I have one for sale, just keep forgetting to post it on classified. It was great, fit my B8.5 without any issue. I have to take it off when installing APR Ultra. Boost noodle doesn't clear the brace.

PM me if you are interested.
