Seems simple but took awhile to get it down.

If you start applying too much peddle, too quickly, there is an abrupt transistion of weight from rear to front. Starting gingerly and adding force, smooths out the weight transision and the car is happy with that.
Conventional wisdom is to squeeze into the brakes as quickly as you can without upsetting the car, and then come off more gradually as you begin to trade off braking for steering entering the turn. Key word are "without upsetting the car", and with the Z4M it may well be that we simply have to come into the brakes, as you said, more gingerly than one might in another car.

This is really valuable to highlight as we're dissecting our data, comparing to other cars, and consulting the experts' literature on data interpretation--our braking profiles probably should be a little less steep coming in beacuse of our inherent (short wheelbase) instability.

That thought, and what we've seen about the incompatibility of heavy braking and even a little, teeny bit of steering input, make for a pretty good day's work. Miller Time! (Actually, Spaten Time!)

Thanks, Jay!
