And for the more technically minded, the skim removes typically 0.25mm per side. And after cutting the surfaces should be given a hone/burnish to remove some of the 'ploughed field' texture. If not you will eat your pads at two or three times the normal rate until they have cleaned-up the surfaces themselves. So if you want to maximise your pad life make sure the skimmers do the hone and / or you run with some old pads for a 1000 miles or so. I guess any new disc will give a higher wear rate of the pads initially but I haven't measured this so cant say how it compares with skimmed discs.

Crikey, you learn something new every day!
I was always under the impression it was the Torsen type limited-slip diff that didn't like the wheels being driven - in effect the power path going backwards through the diff, specifically the helical worm drives that form part of the LSD basket.
I'd always assumed the gearbox was splash lubricated - I've never needed or bothered to check otherwise.
The S2000 just keeps surprising me.

Some cars do have a diff pump - cars with torque-vectoring diffs, usually.
But pumps in cog- (& slush-) boxes are more usual.
