How much camber?

I've got a Gen 2 car. Set up the car to the Hoosier recommended setup. After first weekend on the Hoosiers, the tires seem to be wearing heavily on the outside. Not so much on the inside. How much camber are people running with the Hoosiers?

Ill caveat this with this is only my third season so still learning to drive the car rather than optimize the setup. I am currently running -4.1 deg front / -3.9 deg rears. We are checking the inside and outside wear markers and adjusting. We are thinking the coming race weekend it might be good to check temperatures across the tyre, at least inside and outside. So far we have only run tracks here that are counter clockwise so we end up switching tyres left and right every two sessions to keep more wear life in the tyres.
You can see my setups for various tracks here, they are a minor adjustment of the base setup.

Had same experience in early season tire testing. It's very track dependent and seems to occur on tracks with high speed, long corners. In the case of Thunderhill, we saw outside wear on the RR and inside wear on the LR as the track is dominantly counter-clockwise. T2 is the primary cause as it's a wide 180 degree corner (4th gear in a Gen 2) and typically did wear the inside more. The fronts had the same wear pattern at the high end of the recommended setting.
We've upped the camber significantly from the recommended setting and after the last weekend at TH with the newer settings we had slightly more inside wear. Others who made the same changes at different tracks noticed much more inside wear, so your mileage may vary. I'd suggest going up at least .3 degrees (or more) and see how it turns out.
The other process we're using, especially at tracks like TH where the wear pattern differs significantly left to right, is to rotate the tires after each session side-to-side. Don't see any negatives in performance right up to the end of the tire life (which will likely be the wear bars before a major drop in performance.)
