I have a 1973 road race car that I need to get aligned. I was curious what camber, caster and toe some of you run on your race cars.

I run slicks (27x14x16 rear) and (27x13x16 front).

Thanks

I race a C2 (same chassis) and run the following alignment specs: Front 11/2 degrees neg camber, 21/2 degree pos caster, 1/16" toe-out
Rear 11/2 degrees neg camber, 1/16" (total) toe-in

Please note that I ran considerably more negative camber but ate up tires. I recently used a tire pyrometer to adjust camber for even tire temperatures across the tred surface, and ended up with these.
These specs will get you in the ballpark, and allow you to adjust for your personal style, and the track. You can try more aggressive settings if you're only running autocross.

And I would NEVER run "toe out"!!

Alot of your alignment settings will depend on your spring rates. I don't run full slicks, and my springs are relatively soft (cut 550's in front and 420 lb composite rear). Use a pyrometer to get your camber settings, you probably will want to max out your caster positive without sacrificing your camber, and your toe settings in particular will be based on your driving style and preference. C3's have a lot of bump steer and running super stiff springs will minimze that but will sacrifice mechanical grip. Running more static toe-in in the rear will reduce the squirm under hard braking due to toe-change as the suspension unloads. In front, some toe out helps initial turn in, but with bump steer it can make the car nervous in the corner, so probably for the tracks you can run a little toe-in and it will feel more stable on the straights. My alignment settings are for autocross and are probably a little too agressive camber-wise for a road race setup, and I'm not sure how they would work with full slicks. That said I run about 2.5 and 2 neg camber f/r, and about 1/8" toe in f/r. Not too sure what my caster is right now, but the car handles pretty good.
