I've put everything from the stop tech braking white papers http://www.stoptech.com/docs/media-...ng-systems into an excel sheet to help calculate what brakes I should be using for my car. Some of the values don't seem to be coming out right though as I'm getting negative values for temperature during single stop braking event.
As you can see with the attached image I threw in some numbers to check the validity of my equations. I used a car that weighed 2000lbs 1100 in the front, 900 lbs in the rear stopping from 200mph. When I plug in the larger rotor weight I get a negative temperature.
