asymmetrical setup?
the tracks that we're on are biased, there are more rights (or lefts)
we have run a slightly asymmetrical setup for years, as we tune to tire temp
but we're thinking there is actually more to be had, as one of our tracks is like ALL rights, with a couple of small lefts.
anyone?

My findings suggest yes, and I have been wondering the same thing.
I already run slightly different tire pressures left to right on certain tracks and it seems to help keep temps more consistant. I have thought about running .25 or .3 degree more negative camber on the "dominant" tire to even tire shoulder wear as well.
In the rear I am geting nearly even wear, and temps even out with a 1-2 PSI pressure change from left to right.

also at thunderhill, turn 5, the bypass, it helps to raise the car a little so it can land properly, that made a bigger difference than we thought, instead of waiting for it to land bottom out and then be able to drive, you just drive

I remember one of the F1 commentators remarking how F1 setup changed when Jac Villeneuve left CART for the series. Prior to this it was F1 custom to square a car up and not consider asymmetrical setups. Apparently in CART, with the oval influence, asymmetrical setups were very common on the road courses.
The last year I raced my own car and we dominated the year at Mid-Ohio, a good deal of the speed we found that year was the asymmetrical setup. At Mid-Ohio you need to get through the Carousel quickly and you need to carry a lot of exit speed out of the keyhole. Both are right hand corners. The gains we made in the right hand corners obviously outweighed any losses in the lefts. In fact, we were usually loose through the left hand T1, so tightening the car up there was an added plus.
We went beyond camber changes. We played with weight jacking to tweak the chassis, allowing it to naturally turn one direction better than the other. A little weight jacking goes a long way. A half turn on the coil over can produce results.
