Cheers all for the advice. I've just ordered a full set of RS-29's from design911 for £480 all in, cheapest by a long way on the net. For some reason Porsche/Brembo pads are way more expensive than AP pads!
I've decided that I will do at least one track day at Brands soon and of course that will lead to an addiction

so I would probably be making the purchase a bit further down the line anyway. I can live with a bit of a squeal when cold if need be and even if they are a bit dead when stone cold they wont be any worse than what I have now....
