BUT-you don't want positive camber.
My specs:
CASTER CAMBER TOE
FRONT 4˚ NEG 1/2˚ POS 1/8"
REAR NEG 3/4˚ POS 1/16"
This was fine for the street and acceptable for some track work. Straight tracking above 100 MPH, excellent turn-in, and no appreciable tire wear before they were at replacement age anyway. Makes it very responsive to steering input without being 'nervous' on the highway.
Tucking the tops in will also aid any further lowering.

Chas - I was using ERA's specs - camber - 0 +/- 1/4, caster 4-1/2 +/- 1/4. Where did these come from? Actually, not to argue I was shooting for as close to 0 camber as I could get but I did get a bit more correction on camber from a certain dimension shim than the ERA manual indicated. The manual said a 1/8 inch shim F&R would change camber 1/4 deg. I started out with neg 11/16 deg and added 3/16 inch of shims and got 1/8 positive. It looks like I should have just added a 1/8 inch shim.

I plan to check ride heigth and re-run everything once I've had a chance to put a few miles on it and I'll pull a little of the positive camber out of it then. Not sure about 1/2 deg negative though??

Not sure I will want to go any lower - my mufflers hang down about 1/2 inch below the frame rails which comes out of my clearance also. I have them sucked up about as high as ERA's header collectors will let me without putting a bend in them. But, I'm not sure I want them much closer to the floor pan. So, I'm going to have to watch for speed bumps and curbs both on the nose and mid-way between the wheels.
