Hi there, thanks for joining us for another episode of No Dumb Questions! Jeff Braun and I sit down to answer your questions, and we promise – there are no dumb questions, maybe just some dumb answers.  On this month’s episode, Jeff and I discuss the validity of testing on used tires. We also dive into the concept of a “momentum car” and how the approach one takes when driving a “momentum car” may differ compared to other cars. Jeff is one of the very best race car engineers in the world. He’s engineered cars at every level, and every type: NASCAR, karts, club racing cars, Indy, GT and Prototypes, and even Top Fuel dragsters. But what sets Jeff apart from many engineers is how he can explain what he’s doing, what a car is doing, and even how the best think.
