Standard Mk3 Golf front camber should be between -0.20 and -1.00 degree.
Running the wrong camber will wear your tyres down pretty quickly usually on the inside or outside edge. Any changes to your suspension or steering rack will have an effect on your steering geometry. So you should get it checked and reset shortly after making any changes.
In actual fact, although lots of negative camber will eventually wear the inside edges, incorrect toe settings will kill tyres far more quickly.
Most cars are fairly tolerant of camber - especially with radial tyres.
The problem is that if the camber is out, most likely so is the toe.
Also, Golfs understeer...so you end up scrubbing the outside edges if you drive hard. I run -1.85 degrees negative per side and 2 minutes toe out per side (4 total) which would be considered a fairly extreme set up for road use...and I have fairly even tyre wear.
Slight inner edge wear over the outers...but when I was running parallel toe, it was perfectly even.
In my experience up to -2.0 degrees with parallel toe isn't too hard on tyres.
