Billyo,
I've just brought updated discs and green stuff pads all round.
Try
www.crn-uk.com their on Ebay also. £300 for Zinced plated front vented/grooved and rear solid grooved discs, all the pads and braided hoses, postage £300. Stupid money.
An Mg specialist I know uses his mg zs for track days and has standard discs and EBC Race Pads but he said after a hard track day the pads are noisy around town.
Depends what you're upto with your motor mate!?
