I myself have passed VASTLY faster cars in my stage 3+ Z. All because their owners can't drive as well as they can talk. And MOST people cannot drive thier cars to their 100% ablity. If you can only use 80% of a 600hp car, that is only 480 used hp. Look at it that way.
Don't give a shit how fast the machine is, if the driver sux the machine is sloooooooooooooow. I personaly have ridden w/ Steve, he is a better than average driver.
