Bells and rotors as you'd buy them built up ready to fit from Yozzasport. I'd assumed K-Tecs 312s were AP too, not Hi Spec.
It's more a mate's rate, but it illustrates what you can get stuff for at £wholesale + a sweetner if you take the time to look, rather than going to the end dealer. Drop me a PM though and I'll see if he can source some replacement rotors and a bolt kit.
There must be some mark up on those PF ones though, as a set of replacement 343x32mm Alcon rotors for mine were only £420+VAT and they want closer to £500+VAT for smaller.
I reckon the Autosport show will be a good place to pick up some bargains.
