Jtechsapp on here is selling Comp Brake 6 Pots 350mm Kit for £750, i've got them fitted on my 3 door and I think they are Excellent although some people will tell you AP's are the only thing you should fit, but if going to be 99.9% a road car AP's seem alittle bit of over kill.
Here's the link to Jtechsapps breaking thread:
