The idea with negative camber is to make up for the suspension flex, so that it ends up being flat in turns. So the theoretical optimal amount of negative camber is dependent on the amount of grip (tires, conditions, etc). More grip, more neg camber. But if you don't use it all, the wheel doesn't get flat and you're riding on just the insides through the turn too- rather than distributing load across a flat tire. Negative 3 is a lot of negative camber for a street tire, but on the Kumhos and with all that aero, it's got tons of grip for that camber

FYI: On properly setup and driven race cars, insides wear the fastest anyway. You're always either wearing evenly (in a turn) or wearing the inside fastest (when in a straight line, especially coming out of turns and hard braking). But 2 sessions is very fast.

Maybe it's a tire pressure issue. What are temps across the tire?

Also, camber dictates what part of the tire will wear fastest. Toe is how fast it will wear. The more toe, the more the tires are "scrubbing" rather than rolling.
I thought about that too, that the aggressive negative camber will only put the contact patch flat if you're driving it hard enough, but I'm starting to think there's something about the chassis rigidity, shock stiffness, and double wishbone suspension that makes the viper not really roll over that much.
I'm not sure though, I'm still fairly new to all this!

You can judge if I'm going fast enough for this camber or not in this video from yesterday. A high level AM driver could probably quite easily extract a 1:43 out of this car at this track. Maybe down to a 1:40 if they're really haulin the milk. This was my first real track day with the car and there is much more performance left on the table. I think Turn 6 (the long left sweeper at about 70ish MPH) is what's killing the passenger front inside tire.
