Tire wear opinion

Let's consider two extremes.

If a car keeps doing circles around a skidpad, the grip can be optimized by picking some total roll stiffness, and optimizing camber for the amount of roll that given tires generate. Then the relative front/rear roll resistance can be changed to fine tune the balance.

At slalom, the car rolls left to right and back all the time. If transitions take a lot of time, camber changes all over the place. If the suspension settles quickly though, it can provide more consistent grip, and thus better times.

Different race tracks and different AutoX courses fall somewhere in between these two extremes, and possibly benefit from different approaches.

Sure, I also do the same. Doesn't mean that the same setup is necessarily optimal for both applications.

Personally I also use SX2 tires at the track that generate less grip than RE71R's I use for AutoX. I presume the "optimal" amount of total roll stiffness would be different for these different tires, even on the same course.
