Fully adjustable upper A-arms for ‘67 Barracuda

GRANCUDA said

The factory upper a-arms are not adjustble, just the mounting bolt location is. I have -3 degrees of caster as my car is set-up with offset bushings and trying for the most caster.


I am running the factory 4 piston disc set-up & do not want to get rid of that, may just have to ream out the upper mount.


I will check those SPC arms out and I am really curious about the taller bolts, that could really help alleviate some of my caster issue.

What do you think the control arm mounting bolts adjust? The frame? They most certainly are adjustable.

So you have NEGATIVE 3 degrees caster WITH offset bushings and that's ALL you can get? Are you 100% SURE you installed the busnings the right way? I would double check that. These cars are difficult to get what I would call a "modern" caster setting, that's for sure, but usually with offest bushings, you're looking at 3-4 degrees positive caster. I would surely investigate that.
