Quick Performance 9" Rear Pics Inside I've noticed there's a lack of decent pics of this rear end, so I'm sharing this with everyone:
Mr. UPS Guy dropped this off conveniently at my garage door hidden behind my Volvo while I was a work:
Rut roh!! Mr. UPS Guy appears to have torn a massive hole in the side of my 75lb box. No worries though since everything was in it!! All I have to say about that is:
This thing is AWESOME. All the welds are absolutely gorgeous. Here's some 9 inch rear **** for ya:
THICK tubes! I don't know if this is common or not, but the tube ends were even welded internally for extra support:
Torque arm mount:
Now for the bad. It looks like my UMI LCA relocation brackets aren't going to fit. They need to be about a 16th of an inch wider to fit properly:
Not a huge deal I don't think. I'll probably end up grinding off a little bit of material on the house and the brackets to make them fit..

That thing looks good, and you can't beat the price, i actually gave quick performance a call before i ordered my MWC 9", the guy at quick performance was great and answered alot of my questions, he said that you can order the rear end with re-location brackets already installed, any reason you didn't go that route?

That sucks regarding the LCA brackets. I got the following back from Mike regarding LCA brackets:
"As of now, we are not offering any options for LCA relocator brackets. We are testing a new design and plan on manufacturing new brackets sometime in the near future. If you would like to use your LCA re locator brackets, that will be up to you."
No biggie though. I can weld them myself. I'm glad the UMIs I have on-hand are as close to fitting as they are.

Any chance you'd be willing to swap a set of brackets with me for providing these pictures? The brackets I have a brand spankin new, but were bought around 6 months ago. I'll pay for shipping both ways. I'd GREATLY appreciate it!

I have one in my car now, been in there for about 3K miles. I have a few tips I can give you on the install. Don't use an adjustable torque arm, you have heim joints on the mounting bracket and on the torque arm, this creates a hinge and you TA will move back and fourth about an inch, you need a non-adjustable TA. Next, fit your bracket to the TA before you paint or powder coat it, I had to do quiet a bit of grinding on mine to make it fit the torque arm, of coarse i did this after I had it powder coated, lol. Lastly, if they didnt send you seals that go in the axle tubes, get them, the axle bearings leak and get gear oil all over your brakes. Once it is in, you will love it, no more worries about granading your RE.

The trend to spend whatever it takes to make a car look nice and have plenty of HP followed by shortcutting suspension components is going to get someone hurt, hopefully those using this torque arm mount never allow children in their car!
Trying to think of a nice way to describe what is blatantly wrong with that torque arm mount is difficult to do. With that being said here is a warning.
Those spherical rod ends are NOT strong enough in this application.
I've already said more than I wanted to but if one person that has this listens then it will be worth the risk of making the purchasers of this system mad.

Defamation is a pretty easy thing to get caught up in on the internet. I sure hope what you said is true (and can be backed up with finite element analysis, tensile, and shear strengths of the components involved) for your sake, because you've opened yourself up to a lawsuit if Quick Performance sees this and loses a sale over what you've said.
With that, I haven't done any static analysis short of determining that my torque at the axle is well below the shear limit of my 31 spline Moser axles going in this.
What specifically is going to fail? Are the threads going to pull out of the bottom torque arm mount joint? Will the bottom heim joint stretch and snap due to a low tensile strength?
Honestly, I don't see how it's any different than the heim joints on a UMI Performance adjustable torque arm:
If anything, the torque exerted on the QP mount is actually less than that of the UMI Performance adjustable torque arm because the joints are located closer to the center of the axis providing the torque. for those that haven't take a statics course, the further away you get from the torque point, the more force is exerted (hence why cheater bars break bolts loose).
My post back to you isn't to induce further conflict, but rather to induce further information (proof). I'm all for safety, so if you can prove your point, I invite you to do so. Thanks.

I can only hope that You and others purchasing this package will replace the rod ends with a stronger part. The are not that expensive.
If You want engineering data, google the brand and part # off Your rod end, then compare this to the data from the rod ends pictured on the UMI torque arm. You will be amazed at the difference! Yes I can tell this from the photos.
BTW, the lower rod end is only going to be stretched during hard braking.
I wish You were close enough or willing to come to Wichita, I would be glad to share whatI have learned the hard way with many years of chassis building. Component selection is only one of many considerations prior to building and selling a product peoples lives depend on.
My motivation is not to slam a product so I can sell more, I'm very comfortable with the current volume of sales I currently have.
Please call any time You like, My number is listed below. I think at the end of our conversation You will be glad We talked.

Your post will not induce any conflict from Me. Apparently My description of the problem and My motivation to post the obvious problem with component selection (the rod ends) has been misunderstood. My intent was to share My knowledge of proper component selection in a highly stressed application. The rod ends pictured are not designed for this application.

I'm also very curious how you can tell just by looking at the photos that the rod end isn't sufficient. Please educate us! Thanks.
