Here you can see the Model A motor and the wheels with the Model A mechanical brakes. You can also see all the salt that gets splattered on the cars. Just for the sake of clarification, this was a pit car, not a race car. I think the owner (a really cool guy named Steve) hit the car's top speed on the road between the pits and the starting line. Oh. Check the "necking knob" on the steering wheel. If you don't know what this was for, ask yer grampa.
