Hotchkis TVS for A-Body's!
With the stock upper A-arm with Moog 7103 offset bushing resting on top of the Hotchkis Upper Contol Arms:
I could never get close to this much caster (~6.0 pos) with 1.5 negative camber. BTW this it was 1.5 negative camber equal on both sides. But we triped the lasers and moved the car. It's so sensitive just little thing throw it off.
Since I drive the car a lot we went with 1.5 neg camber. If it were weekend fun only type car they said go with 2.0 neg camber. Also I could/should have went up to 8.0 deg positive caster, but we didn't have time to go back. With the Hotchkis upper A-arms you can get whatever caster and camber combinations your heart desires.
Also, note the picture above how the angle of attack the A-arm legs are the adjuster bolts. If make the A-arm leg straight, you don't get as much alignment adjustment when you adjust the heim joints.
** Another thing situation I've seen from people running adjustable upper A-arms... I've heard of people taking them to alignment shops and the technicians telling the car owner they have to take the A-arm off to adjust caster and camber. I don't think that is true with most these aftermarket arm. I know it's not true with the Hotchkis A-arms, because they keep the factory cam eccentric adjusters for fine tuning of caster/camber. The instructions are clear and tell you how to set the upper control arms before you bolt them in. Then they tell you the spacer to run on the sides of the heim joints. If I wanted more than the 6.0 degrees of postive caster I should/would go back and swap the heim spacer around.
