I had noticed that on Friday, when qualifying was held in the wet, many of the cars approaching the hairpin curve locked their OUTER wheels. But usually, dont we see that when braking into a corner, the car a tendency to lock its inner wheels? (due to weight transfer to the outer wheels thus loading them up,at the same time lightening the inner wheels).
My best guess is that, since they were taking the wet lines when approaching the curve, their outer wheels would be on the racing line, which would be slippery because of the rubber previously laid down.
If anyone had insights into this...do post it up.
