More Negative Camber Set-up

[MUSKOKA800]

Anybody here have any experience with extra negative camber set-ups for street driving?

I need to do something to eleviate my tire to fender rubbing during aggressive turns, road dips and when the car is ladden with passengers. No problem at the rear, just the outer edge of the fronts.

I recall Loren stating that an extra -1.5 degrees from OEM spec. would be fine for street running. I'd be willing to go even further providing the car doesn't get all darty, which I suspect it might with the 215 tires. Especially in the deep truck ruts our highways and streets offer.

Who can suggest a reasonable starting set-up?
Perhaps I can cut a deal with a local alignment shop to make minor front camber adjustments so I can sample more than one setting while not paying for a full alignment job each try???

OR, perhaps I should just buy a magnetic camber gauge and go at it myself??? I did have the camber bolts installed back when I got my post lowering alignment done.
