Knut - What a great post ... you da man! I did want to clarify that it is technically possible to correct caster errors if they are sufficient to cause handling problems. If the caster differs more than 1/2 degree from one side to the other, you will notice that the car is directionally "twitchy" - a lane change can happen by just thinking about it. Winged1 had an error that was right at 1/2 degree, and I considered the car to be "quick into a turn" - a matter of perspective, I suppose. You can change caster by adding shim washers between the rubber donut bushings and the lower control arm. Add shims on one side of the LCA interface, and it will shift the caster value. Since your caster values are fairly close, you're good to go. Thanks for giving us the scoop on the SS lower control arms, and also the great explanation of the various suspension parameters. If you happen to have the old LCA that broke, I wouldn't mind getting ahold of it, and having a peek at the fracture surfaces. We might learn something more about the failure. Please advise if that would be of interest to you.
