Yep, you'll find out very quickly that track time is very different than street time. Everything on the car gets pushed really hard on the track, street stuff just doesn't cut it. Brakes, cooling, seats, etc.

Fluid control is very difficult as the car gets faster. We had problems with everything on Tim's Valiant. Diff oil would come out the breather, transmission oil, engine oil, PS fluid, etc. All of the breathers need to be modified for the track. Building a road race car is a lot different than a drag car. I had no idea at first but after a few track days it became really obvious that everything had to be beefed way up.
