How fat is your car?

Stig's analysis suggested the problem was two-fold: first, that by tearing so much weight out of the back, we unbalanced the 207, losing a bit of grip, a problem exacerbated by the slippery conditions. Second, and more importantly, he didn't rate the wet performance of the tyres on our lightweight wheels - P-Zeroes, remember, which should have been better, grippier. Properly set-up, Stig reckoned, our 207 Superleggera could have saved three seconds a lap. But it wasn't set up properly. It wasn't set up at all. Just as power is nothing without control, so lightweightness is nothing without finesse. Motorsport is an exact science and we are amateurs. Crash diets don't work, kids.
