Here's what I want you to do:
Explain in detail exactly what causes what to move and how much and how EXACTLY that affects camber. Think about this...what is moving and what else has to move how far to have a measurable difference. Don't assume, don't generalize and don't cop an attitude, just think about this. Walk through everything that would have to happen step by step.

Here, I'll make it easy on you...look at the image below and tell me what part is moving to change the camber when you add a 1" spacer:

I couldn't find any good diagrams to illustrate my thinking on the camber, and i don't really care enough to try to prove it so oh well...
However, there is another effect that can cause increased inner tire wear... scrub radius change. This diagram sums it up nicely. Changing the scrub radius can also significantly change handling feel so keep that in mind as well.

Yes i know the picture is showing different tire sizes but the spacer will move the tire center out just the same

Scrub radius is a different story. We are discussing camber. Look at the pic I posted above and identify the part that is moving to affect camber.

According to that picture i can't see a way for it to happen. Perhaps i was thinking of a double arm setup. Either way, someone was asking about wear due to a spacer. Scrub radius change is a potential answer and also my main reason for advising against larger spacers up front

Here is what you are thinking....and there is some merit to this (however small) but this applys only to a swing axel car like this old VW.




A mustang has a control arm and strut. The ONLY way to change camber is through a physical movement of parts, extreme bushing deflection and camber curve.
In order for the camber to change through the curve the wheel would have to travel upwards.
Will a 1" spacer lower your car enough to travel through enough camber curve to make a measurable enough difference? Of course not.

Scrub will change with wheel offset the same as with a spacer.
No net difference between the two.

I just put some on the rear of 2011 gt but was scared to open the car up on top end. So I sit now at Discount Tire getting them removed. Now I feel better with WOT.

Fabman has pretty well correctly summed up everything as far as spacers affecting camber. There is no affect at all in the rear. If there are wear problems on the rear tires and they are correctly inflated, there is another problem other then the spacers. Back to the original poster's question, the Coyote brand (as mentioned above) are the ones that I have on my 2015 GT tracked and I have had no trouble with them. I have had my car at WOT on the street and the track in excess of 130 mph and feel perfectly safe with the spacers.

I know, doesn't make sense but, those were the results I received. Sorry OP not to thread jack, just thought I would share my results with 1" spacers.

The rear was feeling sluggish and not firm as it should. I do not recommend them.

No thanks, mine are only 10 years old, stronger than the wheel and the axle both, and are race proven to over 150 MPH.
I guess you just gotta be smart enough to operate them.

Summary:
Use good quality spacers.
Install properly
Don't slide into any curbs.

What would be the correct torque spec for the spacers

I'll throw my 2 cents in the ring. You may be increasing force/leverage on the wheel/bearings/suspension parts but you are increasing camber 0 degrees.

That sounds good to me and as I believe Fabman would say, any increase of force/leverage on the wheel/bearings/suspension parts, would be no different than if you had done the same by way of the offset in a wheel.
