Adjusting front camber is that easy, but you might throw off the caster.
The easy way not to mess up the caster is to remove the same thickness of
shims from the front & rear bolts. Note that shims can be different
thicknesses, either 1/8", 1/16", or 1/32". You will throw off the toe doing
this, so unless you're comfortable adjusting the toe, I'd suggest you take
the car to a competent alignment shop.
You can't get enough camber in the front of a C4 to worry about tire wear,
but excessive toe will kill the tires quickly. Ideally you want all the
negative camber you can get up front, and about -1 degree in the back. Keep
the toe around 0 for a daily driver, maybe 1/16" out in the front. No need
to adjust the camber at each autocross, just set it and forget it.
