A-body chassis dynamics, handling

One can go too stiff on springs. As said before, the weight of the car moves around, and that affects grip. More weight on the outside tires improves grip, but not more than the sideways centrifugal forces. Stiffer springs reduce body sway, and body sway causes the tires to lean in relation to the ground. Stock '60 type suspensions were very soft, and caused excessive body sway and excessive positive camber on the outside tires. A lowered A-body has more camber gain than when at stock height. As the tire moves upward, the upper ball joint moves toward the center of the car faster than the lower ball joint due to the angle they are at, and the fact that the upper arm is shorter than the lower arm. This is similar to what happens to the early Shelby GT350s with their 1" lowered upper control arm mounting holes. As for shocks, I have a set of QA1 Stocker Stars sitting in their boxes that I need to install. I've heard a lot of good things about them. I've heard good things about Konis too, but that they are discontinued. I've heard a few bad things about Edelbrocks, and lots of bad things about KYB.
