A buddy of mine here was trying to give me the quick and dirty. I guess he routinely took best overall when he was in the game... with a heavily modified Subaru. He was extremely discouraging.
For a car as large as ours, I was curious on the optimal tires. Go with 4 street slicks or something more conventional. Don't want to dish out too much money.
I would be most interested in stock runs. They label our cars in the 'G' class, which is like a Chrysler Sebring v6.
