You do have too much camber. The lower you go, the more camber you're going to get but even if you were scrapping pavement, you wouldn't have that much camber. I'd mess around with it but, I'd probably go somewhere in the middle. In the 1:1 world you can get extended spring plates to help cut down on this so even if you're a little less than what would normally be on a swing axle car, it could still be convincing.
