Shhh, they don't know that.
Anyway...the point of all that...I think we're doomed in STU without more tire, or (ideally) some sort of tire allowance based on weight & power. The unscientific testing that Terry and I did last year was enough to make me not consider STU on 285's.
Now, from a non-competition point of view, I have more fun actually driving my car on the street tires. Unfortunately I think winning is more fun than driving.
