Anyone using the Dr. Gas Spindle Length Spacers and have they made a difference? Here's the write up:
This Bolt-on kit lengthens the spindle by two inches. The angular relationship between the control arms and instant centers (there goes that engineering stuff) are revised and actually reverse the direction of camber gain with suspension travel. This kit bolts to the top of the spindle, and then attaches to the upper ball joint stud.

I think there is a pic of them installed on this page:

They are excessive in my opinion. The front roll center is raised too high and I have heard of complaints of inner tire edge wear for street driven Camaros.
The guy who came up with these autocrosses a second gen Camaro. Second gen Camaros are less sensitive to taller uppper balljoints because the spindle is taller to begin with, - it's less of a percentage change.

If you are running a race-only Camaro, you could try them but I don't like how they put a straight shank bolt in a tapered spindle hole.

David, have you heard anything about the durability of those spacers?

They seem to last OK. I have talked to a few people who have used them for some time with no breakage. I think one guy said they slipped side to side just a little. The lower part bolts to the spindle with a straight bolt placed into the tapered spindle hole. This seems risky to me but it seems to work.
The roll center is raised VERY high so a smaller anti-roll bar would probably be needed. You may experience the front end bobbing up and down slightly when cornering hard on flat or off-camber roads. For banked corners, you wouldn't notice any problems. I talked to one guy who used these spacers PLUS the Guldstrand mod. I thought that would be almost undriveable, but he's driving it!
There is a .5" taller upper balljoint and I think now a 1" taller upper ball joint available which is probably a better way to go. Mark at SC&C has them.

Thanks David - I spent a ton of time on your web site! Thanks for the info - that's the input I'm looking for since my 69 is street driven and rarely sees the track.

For a street Camaro the best deal is to get as much positive caster as possible, IF you have power steering you can get Tubular upper A arms and run around 5 degrees positive caster. The next consideration would be to do the Guldstrand mod or taller upper balljoints. An all-out effort should probably consider the AFX spindles from ATS.

I have a set of the Dr Gas units if interested as I went a different route.
