The biggest test will be to take the car up to about 140 and stomp on the brakes and see how far it takes to stop. You would also need a guage between your foot and the pedal to measure how long and hard you had to push. I could do all of this with the DAQ setup I have in the car. :)
What would be nice is to have an Ir temperature gun for measuring the temp of the rotors on this same run. Link that into the DAQ as well. :)
