If you look at the dedicated autocross racers, you'll see many of them do run
quite a bit of negative camber. Tends to make them rather undrivable on the
street, but it does wonders in the turns. Since you want the tire tread flat
on the ground in a turn, you use negative static camber to compensate for the
roll of the car and such. It's a balance. I'd start off conservative, and
work progressively more radical.
Yes you can measure camber in your driveway. A couple of boards and you've got
a rough idea of it. One board going across the driveway in front of the
tires. Two vertical boards attached to it, going up beside the tires. Measure
the distance from the vertical board to the tire side, top and bottom, and that
will let you know roughly where your camber is. The better you make the wooden
jig, the more accurate your results.
By push on the front wheels, I take it you mean the car would plow wide on the
turns, understeering. The load of turn will be put across the front and the
rear. The more of the load you put on the front, the greater the tendancy to
plow. So you either beef up the front to take it (larger tires, more pressure,
etc), shift the load to the rear (add rear swaybar, remove front swaybar, etc),
or both. Again, start conservatively and work progessively more radical.
Spitfires, with their swing axle rear suspension, make like rather interesting
when you shift load to the rear.
For adjusting the camber, you can also use washers. Nowhere near as precise as
shims, but effective none the less.

Thanks for the info guys! Maybe -2 to -3 is too
much...I just didn't know any better!!! Autox is
the reason for doing this but I still want to drive
on the streets. I'm also looking into putting
competition springs on the front. Are the ones that
VB carries worth the money or should I look to
another source? At the last autox, the front wheels
seemed to have a push on tightest highest speed
corners. This is the challenge that I want to work
on!! The rear spring seem to be somewhat shot so I
plan to leave it alone for now. Rear tires are
showing some neg. camber now.

PS I like the idea of making my own shims.
VB gets something like 2.95 each!
PSS Is there a way a layman(like myself)
can measure camber?
