Improved Handling

Yes, 3-4 better. More stable and high speeds. A little camber gain in corners too. Drag guys IIRC, even run more.

You seem to be the guy that would know. I plan to use the offset bushings. If I can get that much, can I get away with 3-4 degrees on the street, or should I maybe use a bit less? I've got an original 16:1 manual box I plan to put on my car, and plan to run about a 215 to 225/60 15 radial front tire. The car has a small block.
