When I said we took extra care all I meant was we did our cool down lap after a 15 minute session and then drove carefully up and down the runway at Croft for a further few minutes to dissipate as much heat as possible from the discs before parking up again. Basically, if they were still 'ticking' as it were, we drove until they'd stopped. None of us suffered warping or fading on the track. Obviously had we been lapping the Nordschleife, as some of them did recently, this may not have been possible/sufficient and they may have done something else, I'm not sure.
When Keith says the inadequacies are in the caliper he's made it clear he's talking about stopping power, not cooling. He's made me as aware as I can be, with my limited mechanical knowledge, of the problems surrounding the heat transference between rotor and bell housing and the pins and stuff. I agree that if my funds were limitless and I tracked the car more than the 3 times a year I do now, in short 15 minutes bursts, then I would want to address these issues too. I don't think its fair to refer to him as some guy in a shed. He knows me(my budget), my car and what I intend to use it for. He fitted Movits to my S3 and they were excellent. So far my experience of this option has been excellent too. The ABS, ESP etc all function as before and my stopping power has improved significantly, which was what I set out to achieve. They were a very good price relative to other options and they look and do the business IMHO.
. I bought a set of movits at a reasonable price so I never followed it up.
