If you're optimizing for tire life, I'd go for the Hankook RS4. I run both the R888r and the RS4 (on my other car), and the RS4 is only a little slower, but really really hard to wear out. Currently planning a 14-hour endurance race with only one set of RS4s (and a set of spares in case of accidents).

It's the other way around unfortunately. Here's a typical camber curve on a strut-type suspension (source [1]):



The right part where you get more positive camber is the one you don't want. It happens with more suspension travel -- softer springs, softer sway bars, pushing the car harder.
