Racing the stripe if you have the lead

What tips or tricks do you have to not take too much stripe when you are in the lead?
When I am ahead I'm always worried about breaking out. I try to put the other guys windshield in the middle of my door window. I figure that ought to give me about 2 feet of stripe.
This is a technique that I failed to follow last Saturday and had about 3/4 of a car on him at the stripe and guess what? You got it, breakout and he wins! :BangHead:
