Ultra Racing Rear Subframe 2 Point Bar

Anyone has this installed? I have the front, rear strut bars, all the under body installed. It made a huge difference. This is the first time I see the rear subframe bar for sale, wondering if anyone have experience with this.

Never seen that one before. They had this 2-piece set for the rear subframe or control arms, but discontinued it. Looked everywhere to try to scoop up any inventory but they were gone worldwide.





I’d say that piece you posted would be very effective in tying the rear together. Looking around on their website however, looks like it may only be for PFL. Strange. That area of the rear end does look somehow different than my 2012 coupe though I can’t put my finger on it...

I sent the eBay seller a message to see if it’ll fit. Stay tuned.

Were you able to find this one through the eBay seller from Malaysia? I combed through yesterday and didn’t find it. Only on the website above and coincidentally that contact is right here in Fairfield CA 25 minutes from me.

The usual Malaysia seller doesn’t seem to have it. Found it from a UK seller.

If the CA contact has one even better though.

I have that on my sedan - hard to tell how much it alone added but the full kit ( minus the lower front that didn't clear the ARH's) truly transformed the car on turn entry and exit... I noticed it more perhaps as I'd done the widebody before they were installed and the 325's - now it's planted and flat period.... no inside lift and the nose plow is lessened it seems.

I got it via ebay thru the usual vendor we all seem to ... I'll try to dig that out of my old ebay acct and post it shortly.

I was under that section of the car tonight messing around trying to get my driveshaft off. Different problem. Anyways yeah this rear sub bar appear to fit as E says. Looks like it’ll bolt to the the two rear subframe bolts that go up through the rubber bushes and tucks up in a space near the spare wheel well, for those of us that still have ours.

I don't see how connecting one end of the subframe to the other side of the subframe would do anything. That is a solid steel part, and nearly a straight across connection. Unlike strut tower braces or the lower subframe brace where you are directly connecting things where they aren't directly connected. Im sure i could easily build something like this if you guys really want. Probably a lot better and more useful. What are these bars normally made out of Aluminum or stainless/steel?

They’re enamel coated steel. Super sturdy.

Got it. Same construction as the others. Heavy gauge steel with white enamel, plates for the UR logo and bar model etc.
Might get it on this weekend.

Just wanted to give you guys a heads up. Have been working with the Ultra USA guys on this and they’ve been great. Ran into a problem on the install. The mounting points don’t fit the subframe bushings where they attach. The posts are just a little too wide, maybe by 1/4”. I can probably get it on by grinding out the outside half of it so stay tuned. It may be an issue just on the coupes, don’t know yet. I’d hold off on purchases until we can get the fit sorted out.

Weird. Every other brace had been spot on or allowed enough margin. Let us know if they remain responsive.

Well there you go. How do you like it?

Do your rear subframe bushing holder things look like this?

my bro, did you ever finish installing this bar? Is it worth it? I’m about to order my 2nd round of parts from them and trying to decide what to get.

Haven’t gotten around to it. Was waiting until I had the patience to drop the whole rear to do the subframe and diff bushings. Never heard back from Ultra on the fix.

I’m not even sure if I can mount that bar to my c207. Ultra sells one for my car, but the mount is different. My mount doesn’t have the two little holes on each side like the bar and your car has. So I might not get it. I’m trying to figure out how it even works. The subframe is already large and beefy.

My car already has both middle lower bars too. The long 4 point one, and the one by the transmission. So no point getting those either. So all that’s left is the 2 piece front bar, but the UR rep and the website says you can’t use the two piece with the larger one together. Although you and another member said you guys have used both at the same time. But I’m wondering is there a difference between w204 and c207.

This doesn’t fit my 2013 sedan neither so maybe Mercedes changed the bush design from 2012-2014. As another person above said it fit their sedan I bought it but it doesn’t fit on mine.
