Interesting approach. You could wind up with a very legal-looking setup that
would solve the general handling problems. I think you should look carefully
at the roll center as well. You can calculate that or get software to do it.
I need to find a copy of the software that was used originally to design my
upper arms--the guy who had it moved to Costa Rica (and I don't think he
actually owned the software).
The ride height shouldn't have much effect on camber for the small amount of
travel that a TR has. The upper and lower arms are close enough to equal
lengths so the relative angle shouldn't vary too much. I'd have to mock that
up to be sure.
Moving the upper pivot point inwards is how we fixed the roll center. Stock
is 3.5 feet underground--at least from the measurements on my car.
Peyote has a shortened upper arm, and I haven't measured everything to see
what it's doing. It handles very well, though it's not as neutral as the
TR3.

Subject: RE: caster angle
This is good stuff ,i am in the middle of changing my front camber on my 4
and i have the early upper a-arms .I made a really cool jig to set the arms
up on , to measure the lenghts as a starting and finishing points . It also
keeps everthing alaigned to weld when finished . I am just in the middle
of this project and finished the left front corner . It came out to be 7/8
degree negative , from 0 camber starting point . I took off .110 off the
arm . I took .130 off the right front because it had a bit of pos. camber .
I should have taken a little more off each side maybe (the front seems to
stick fairly well already ) but i now have a base line as to what the
camber changes are , if i do it again i will try .150in off the next ones .
Also if you raise the ride height or lower it , i think this also has
effect on the camber . Anyhow , it has been fun playing with this suff ,.
the rod ends that you have are the way to go , for sure . but i don,t think
the tec guys at the vintage events would be happy with me if i showed
up with that set-up .
