To be honest, you are probably better buying new discs rather than from Ebay. You generally get some warped ones on there.
I was looking at the Clubman option on Demon Tweek. Seem pretty good. Bit thicker but compatible with road calipers, fully floatting, etc. You get some new ones like that on Ebay as well.
Pads - Bendix are OK. MCR (carbon matrix) for track but don't use on the road, they don't work at low temp. MRR are the ones for road.
Performance Friction are also pretty good (used by top racers), twice the price though.
Brembo do some amazing pads as well with the Z04 but I believe that this fits only the race calipers. Twice the price again...
