I considered doing the same thing. My primary concern was spinning the car. Even a meticulously balanced race SL-C (i.e., electric water pump moved to nose, engine moved 1+" forward, lightweight sequential transaxle, etc.) will be tail heavy and all of the totaled non-race SL-Cs that I'm aware of, other than the one in the building fire, were ended by relatively low speed spins. IMO this is why good traction control is a must. In any event, excessive rear brake bias gets sketchy quickly. A cable-based system does a reasonable job balancing force and the driver can modulate it via the handle. It would be interesting to figure out how well you can modulate force through current sensing. More of a question about the motor and gearing than software. If you can modulate, then you could add a yaw accelerometer and a "stability control" algorithm to prevent the car from spinning. Would be fun to test in a safe place.I will be tying in my vehicle speed via can bus so that I can adjust the clamping force based on speed allowing the electric calipers to work as emergency and parking brakes.
