- There are exceptions Dick, but most cars will try to spin if the rear wheels are locked up. Not a good idea but could be fun / memorable / scary. What you will need to do depends on your system. If y

- It helps. Due to aerodynamic loads varying with speed, you'll need to experiment to find proportion settings that are optimum for your speed ranges. In other words, if your car has lots of downforce

- Hmmm, isn't that a metering valve? Disc to Drum. Proportioning has to do with front to rear brake bias I think. You need some sort of proportioning (not necessarily a valve) even with Disc To Disc. d

- Road racing cars used to balance front to rear braking mechanicaly - They used two master cylinders and the crossbar on the pedal that pushed on the cylinders had an adjustable fulcrum .

- After 29 sucsessful years on El Mirage and Bonneville I can truthfully relate what was told to me many years ago by more than one very fast LSR competitor. Brakes are for "loading and unloading" safe

- Jim, now you are taking a simple idea to the extreme. No, depressing the clutch in order to shift gears does not destabilize the car. In that short of time, not much bad can happen. I am talking abou
