Race engineer, Jeff Braun, explains how the "big boy" ($2 million) simulators work, and how they can be used to develop a car (and what you can learn from the process). This week’s Speed Secret is all about regaining your focus when driving, and Ross expands on it by claiming that the best drivers lose their focus as much as any other driver (it's how they regain it quickly that counts). Ross also explains the benefits of competing in Chumpcar and Lemons racing.
