I hope being Vice Chair of the Club had nothing to do with the level of service I get, indeed I know other Aero owners that the factory takes good care of.
I talked to Henry and Laurie at Williams about their PDI. The pads seemed to have sufficient life left, so they were not removed: why would they be? But it is surprising how much they wore in only 3000 miles since I took he car over. I hope new AP Racing pads last longer.
But a good point about the tyres, I know that it had a new set of ZZ3s when I got it, I was told it had used 2 other rears and one previous front. So it has had a hard life and I'd have been surprised if the pads had not been replaced.
It will, no doubt, all come out in the wash.
