i can't ever remember thinking "gee, those tires are just holding on too well, i wish they would slip more."
i've got well over 30K$ in the car and, although i don't push it really, really hard very often, when i do i expect to get every bit of handling i possibly can. think about it, when you do need that extra traction you probably need it to save your life.
i'll spend the money to get the best i can find.
is the money wasted? i really hope so.
