As with all BMWs using this engine, the Z4 is hard to launch effectively. It wants to boil or bog. Get it right speedwise and there's lots of wheel hop, but it's quick.
Solid, consistent pedal on all stops. Completely confidence-inspiring.
Skid pad: Will not rotate regardless of throttle/steering inputs -- at the speeds reached on a 100-foot-radius skid pad, anyway. Just manage the understeer. Slalom: Very stable during high-speed transitions. Not sensitive to the bump at cone #3. Good information through controls, but not nimble in this maneuver.
