Checked my '14 car, hangar is worse than the '15 one. Brass version is off the same.
Loved my '14 car, beat it to death and it still was good enough to run up front.
First night out with the '15, will be Fri night. I have a feeling it will be better yet. Added a 1 deg shim and called it good.

Maybe the 2013 and 2014 cars had the diff case holes off center and this was Xray's way of fixing it. Idk. I have a new set of 2014 rear toe blocks sitting in front of me and the rear one is visually off. Not even going to open the package, back to amain it goes.

Mine wasn't noticeable from behind the wheel, but it was pointed out to me by a buddy that he could see the back of my car stepping out when viewed from behind. Not a lot but enough to ask me to check my car. That's what started the whole thing for me.

The car feels fine to me box stock even with the issue.

After knowing, definitely not OK with it. And the even bigger issue for me is the manner in which XRAY chooses to handle the situation.

Playing devil's advocate, if you didn't notice it on the track even if it were off, would you still be ok with it?

I'm in no way agreeing with what Xray is not doing. It's wrong and they should correct it. They are a premium manufacturer and this lack of detail is not acceptable.
But, it took a long time to notice so my guess is it's not too noticeable on the track.

That's a fair statement. I just wonder why the team drivers haven't noticed it and had XRAY fix it. Especially on the high grip carpet tracks, you would have thought it would have been more noticeable than on looser dirt tracks. Those folks can pick up the smallest changes in their cars.
Idk.

Ok guys I finally had time to take some measurements on the CMM with different combinations of inserts. I also measured the distance to the centerline of the mount insert pockets. It was worse than I originally thought. All measurements are to the centerline of the chassis. Here's what I found:
Inner hinge pin angles with 0 inserts:
Left 2.73 degrees
Right 3.60 degrees
Inner hinge pin angles with 0 insert right side and .5 insert out on left side:
Left 3.22 degrees
Right 3.60 degrees
Inner hinge pin angles 0 insert left side .5 in on right side:
Left 2.73 degrees
Right 3.08 degrees
Inner hinge pin angles 0 insert right side 1 insert out left side:
Left 3.69
Right 3.60
Centerline of chassis to centerline of insert mount pockets no inserts:
Left .9004"
Right .9280"
Offset of pockets to centerline of chassis:
.0138" towards right side.
I measured my mount at .010" offset with calipers, but looks like the holes in the case are also offset about .004"
No bueno.

No bueno..5 in on right, .5 out on left

The first time I drove the car, I had my trim set straight by eye on the bench. As soon as I punched it on the straight my car veered right, so I had to go several clicks left on the trim to make it go straight. Next time I drove the car, I noticed my trim appeared to be set a bit to the left before I put it on the track, I figured I just leaned on the trim button and threw it off, so I corrected it by eye to get it back in the ballpark, guess what, as soon as I punched it down the straight my car veered right......see where I'm going here?
Sometimes, when you don't know something is wrong, you don't notice it until you experience it when it's better. Have you ever thought your car was working great, then made a change just to experiment and it felt better?
My car definitely felt better on the straight with just a .5 difference in the insert, and that was still uneven.
To answer the other question, and I'll speak for myself, any anger I have is entirely from the bogus responses from Xray, refusing to acknowledge the issue, let alone work on a solution, insisting that everything is correct/within tolerance, and to some extent the tone of some of the responses, which imply that regardless of what I have in my hand, see with my own eyes, and can measure with my own tools, they could not possibly be wrong. Going as far as inventing unrealistic reasons as to why the brace is designed that way, hiding behind their self proclaimed "Legendary Attention to Detail", which seemed to be an attempt to just shut me up about it, all to avoid having to correct it.
I was not angry when Losi had soft pins failing in the SCTE, because the acknowledged it and sent updated parts, I was not angry when Tekno's first run of EB48 had outdrives that wore out right away, because they acknowledged it and made updated parts. When the first Tekin RX8's were failing prematurely from impacts/vibration, and they took them all back in and fixed them under warranty with a new 3 hole case to identify the corrected ones, again I was not angry. I continue to buy and support both those brands, I have (3) Tekno's, (8) losi's, and (7) Tekin systems plus spares on the shelf, partly because of this .
Had Xray just said, gee you're right, we will see what we can do to correct that, or some other response of that nature, I would have understood completely and patiently waited for a solution, meanwhile continuing to run my car with mis-matched inserts, and speaking highly of them for wanting to give the end user the best performing product they could.
