I always ALWAYS run some negative camber. The $64 question: How much? There's a whole host of factors, some of which are:

> How aggressively is the car driven? (i.e., canyon and entrance-ramp carver?)

> I assume radials (otherwise you might actually want 0° camber), but the aspect ratio is important, the lower the aspect ratio, the less negative you need

> Roll stiffness

> Tire pressure

> Wheel width to tire section width

I have run as much as 2° negative and STILL worn out the outer part of the tread first. But, then, I am an animal.

For most of my street-cruiser type buddies, I recommend 0.5 to 0.75° negative.

I like lots of positve caster but not more than 2.5 to 3 deg. or so. More is better for road racing as long as there are no REALLY long high-speed straights -- excess caster makes the car pretty spooky at very high speeds. Caster is somehow hard for a lot of guys to conceptualize. Picture a line drawn between the center of the ball joints. If this line is viewed from dead-ahead of the car, you're looking at steering axis inclination (not independently adjiustable). Viewed from the side, this same line is caster.
