If you tear the nose off of your car, then the brakes can heat up more. Brakes are important to get into the corners. You have to have patience of steel to race there. A fine line defines whether or not to run hard enough to get to the front or not run hard enough to burn up the brakes. If your car is hooked up, you want to get to the front fast.
Every lap presents a different situation there.
I think experience teaches you when to go and when to wait. I like having one pit road. It might just be a mental state, not having to pit on the back, but I think it is an advantage. I am running the Craftsman Truck race there. I'll use it as a test for the Cup race on Sunday.
