as with many things in life, camber is one of those things where "is some is good, more is not necessarlily better"
on the rally cars, we typically can get -2 degrees +/- at the back and up to -3 in front. more than this makes the car very darty when crossing uneven surfaces, such as the camber in a narrow road-- i.e., basically unusable for street driving. I'm back to -2 all around after trying a fair bit more. even at -2, the "knees-in" stance of the wheels is very noticeable, the car looks like an effin' circle-track racer sometimes.
using the notorious napa crash bolts, you may be able to get -2 up front, -1.5 at the back.
depending on your wheel/tire combo, any more than -1.5 at the back tents to produce rubbing probs between tire and spring perch on the strut. 7" wide wheels in 16" or 17" and 215 or 225 width gumballs don't leave much room. and when the rubbing happens, it can give you wicked bad snap oversteer :
which I discovered by stuffing the rally can en route to the alignment shop one time. :
