Really? Awesome!
What that means is, yours is the one pictured above in Hammertone.
You officially have the first production piece.

Just sent you an email Kelly
What's the NVH like on these things? Are they acceptable for both daily driving and track use?

I'll let you know soon, just got mine today!!!
Pictures:
Hotel room key for size comparison-
I don't think this gusset is present on other BMR arms:
Machined Aluminum bearing sleeves...very nice
Very close tolerances on these guys...makes me think NVH may not be too bad...shouldn't be crashing around a ton
Let me know how the NVH is. I'm very interested in upgrading my UCA.
Thanks for posting pics csamsh!
I have been road testing this thing a lot lately. While I will say, the increased NVH is there - this has got to be the quietest, smoothest operating Bearing UCA I have ever experienced. You WILL notice the more rigidness, no doubt....but IMO, it is very "tame" for a bearing UCA.
Bearings are weird, in terms of service life. We realize the importance of a high quality bearing in an UCA application, so we chose one of the best bearings on the planet for this specific piece.
I have no way to predict the life, but I would be surprised to see it not last several years under extreme abuse.
Our low 8 second race car has 16 bearings on the suspension, and they have been on the car for 7+ years....with about 450 passes, and are still tight and quiet as can be. They are all QA1 XMR Series, like we use on most of our components.
This is an actual spherical bearing, and is 1"....so it should prove to last quite a while.

Can it be used with the stock 2011 UCA chassis mount? (I don't need to change instant center.)
Yes.
BUT:
That is the bolt we supply with our UCA Mount. It is the same 18mm as the OEM bolt.....except it isnt stepped, which is even worse.
I NEVER recommend an aftermarket UCA be used with the factory mount. You will, 100% of the time, experience a clunk at some point in the RPM range while driving the car. The clunk from this tolerance difference, is pretty annoying too.

^ A couple companies sell small bushings which take up the slop between the bolt and the upper control arm mount. I used to have them on my car and they worked well. Later I upgraded to the BMR mount and adjustable arm.
Yes.

Gothca. So if you're upgrading from stock, you should get the "Ultimate" UCA and the 2011+ UCA mount. Your mount has two holes on it; which one is the "stock" instant center location? The one closer to the chassis bolts or the one farther away?
Sky, the 11+ Mount we make is unique in the sense that the upper most position, is actually a little higher than the OEM position.
This is designed for a lowered car.
The lowest position, is designed for a stock ride height car that does not utilize LCA Relocation Brackets.
The UCM001 for 05-10 Mustangs, the Upper Hole is the stock location. The lowest position, like the 11+ is designed for stock height.

So on a 2011 car that's lowered with LCA relocation brackets, which hole should be used on the BMR mount?
