Requesting alignment specs w/ .5 Proforged & 3" drop coils

Hi All, I'm headed to the alignment shop this Saturday for the initial alignment since reassembling my 68. I have factory control arms with the Proforged upper balljoints and outer tie rod ends along with Hotchkis 3" drop coils.

My driving plans do not include any type of competition but I do happen to have some beautiful canyon roads all around the area I live in.

Based on what I've read on David Pozzi's site and here on Team Camaro I believe I should request the following specs:

Caster: LF 5 deg positive, RF 5.5 deg positive
Camber -.5 degree
Toe in: 1/16"

Based on my configuration and driving plans is this correct, or are there other considerations such as the drop coils that should change the requested specs?

As always, thanks for the insight -

I think that sounds reasonable IF you can you can achieve it with stock control arms.

I'm right there with you. I had about 3 positive caster at zero camber with stock arms and ride height. I doubt you'll get much more without the Guldstrand mod.

Those specs are fine if you can get that much. If not shoot for as much positive caster you can get at -1/2 Camber. You may get different results with the taller joints than I expect.

Here's what the alignment shop was able to attain with the stock control arms and the .5 long ball joints. They plan to nail the .5 camber once I get some break in done on all the new parts. I like the way it feels, have not been on the freeway yet.

Seems about right with stock control arms on a first gen Camaro (or a 3rd gen Nova).
If the shop tried to get more positive caster, they would have also been increasing your neg camber at the same time.

I had to install aftermarket tubular control arms to get additional positive caster... while keeping my camber at neg .5 (I did not want to do the Guldstrand mod).

I would remove a 1/16 shim on the right side to make camber and caster both go positive. I'd expect the spec to read 4.0 caster and -.5 camber. Then i would remove an 1/8 shim on the left to add camber and reduce caster. I'm looking for 3.5 caster and -.5 camber when finished. The difference in the caster is to compensate for road crown. I'm told the Firestone stores here don't teach that in their training anymore.

Good plan, we going to take another crack at it once I get some miles on the parts and when the new front tires and wheels are installed. Will be sometime in the next 30 days
