Because it's so light, the Boxster Spyder doesn't require the typical abusive Porsche launch -- only a little controlled wheelspin. Shifter could not be better: short throws find home with a palm push. Also very little shift shock or driveline lash.
Distances vary with available grip but are very short nonetheless. Zero fade from firm-to-hard pedal, flat and straight every time. Brakes got better with heat, best run on #7.
Skid pad: Steering is so unfettered by weight that you can feel every last bit of grip ebbing and flowing with the surface and speed. Easy to keep a steady arc by manipulating throttle. With PSM on, it was more difficult to stay steady with throttle breathing on/off then subtle brake application. Slalom: Could only get better with more front-end grip; otherwise, every bit of feedback is useful and every driver input has a consequence. This is a precision driving tool. Eventually it understeers (gently, predictably) which limits the slalom speed. Steering is as good as it gets with crisp turn-in and immediate yaw reaction, and quick enough to catch a slide. PSM is intrusive when on.
