That slope is .0238. The tangent of 1.35 degrees happens to be about the same, so I think the camber is 1.35 degrees negative.
Now perhaps I am doing that completely wrong, so enlighten me. What I don't understand around here is a lot of forum members keep the three size differential between front and rear when the first thing I always thought was a cure for under steer was larger front tires. Some of the AC guys go square which should help things a lot. I get the impression that over steer might help a lot more on and AC course than a road course.

You need to measure at the rim rather than the tire. As for why we dont run square set-ups, some do, however in autox I cant fit larger than 225s up front due to wheel width restrictions in my class. I could lower the rear tire width but in a tight autox course I need all the traction I can get. The car can still be coerced into oversteer when it's needed but I actually haven't had many problems with understeer.
