I know a big problem with Mustangs is the + caster issue. So we lower the UCA 1" or 1 3/4" with the wedged or aftermarket UCA to get more - camber. I also believe that the Global West upper is also shorter then the stocker.

My question is, has anyone ever used a short 67-68 UCA with a wedge kit? Or would this be too extreme? I know on the FOX platform a trick was to use the longer Tbird lower arm for more - camber.

I guess it all depends on how much camber your trying to get. I was able achieve -2 camber with boxed and tweaked stock type control arms. I ended up going to a Vario Eccentric kit to move my lower control arms out a bit, to gain a bit more camber. For a dedicated track car running radial DOT race rubber, you may need up to -3 camber to stop the outside edge front tire wear. My tire wear on the street tires with that much camber is less then desirable.

I think what I said would give a lot of negative camber, most likely too much for street use. But I was wondering if anyone ever tried.

I have never herd of anyone using the 67-68 arms on a 65-66.
I don't have any to look at, but if they will bolt up to the car,
and aren't to much shorter, it may work. When I do the re-alignment
to upper arms, it does make them a little shorter, but not much.

Like Bill said, the thing is to get more neg. camber into the front
end to save the tires and give more grip. With a "vario" camber
kit, it's easy to put in more camber. With a re-aligned stock arm,
you can lower the mounting to 1 3/4" and that will help too.

If someone can put up a photo of the two arms together, and
do some measuring, we might find the answer.

What made me think of it was exactly that! One of the parts catalog had the 2 side by side...just don't remeber where I saw it :p

BTW, I knew I could count on you 2 to answer. Thanks!

The mounting holes are not the same pattern. I can't remember how much, but it was significant.

-----------------
IIRC this is one of the best ways to move the LCA around to adjust the camber....I am aiming for -2 camber as the car won't be a dedicated track car....but also a weekend streetmobile.

But, if you're lowering the mounting point 1" (or 1.75"), does it really matter what the mounting pattern is? :: ::

I think they are too short. IIRC, the difference is about 1", but my memory isn't what it used to be! ::
