I have a question that I can't seem to find the answer to with a search. But I suck at this search function so it's probably out there. Wondering if someone has already tried this. I have never been happy with the backspacing on my front wheels. The tires stick out from under the front fenders about an inch further that I would like for them to. My lower control arms are mounted in the outer frame holes where they are supposed to be. Could I move them to the inner holes and then adjust the upper arms to correct the camber or would this create a different set of issues? That movement would have the tires under the front fenders about where I would like them. They don't make my wheels any more so buying new fronts is not an option. Mark III Roadster.

Thanks in advance
Steve

The inner hole are for pin drive wheels setup, to compensate for the width of the pin drive adapter.

If you use the same configuration of lower/upper arm and steering rack than for a pin drive setup, it should not mess the suspension geometry.

EDIT: I appear to be wrong. Read below.

That is not correct. The inner set of holes are for the donor set of lower control arms. The pin drive setup came with shorten lower arms and used the outer holes.
I think you will have difficulty getting the upper arms moved in and getting an alignment

Rich’s answer is the correct one.

Totem, if you are using 1996 or later spindles that’s part of your issue; they put the wheels out farther than Fox, 1994/1995 Mustang or Factory Five spindles.

Thanks, That's what I was afraid of. I didn't know if I could shorten the adjusting sleeves enough and still be able to get it in alignment or if that would goof up all the geometry.
