with the exception of ebay where is the best place to buy brake discs and pads online as the only place I have found wanted £80 for a front disc for my GPZ now never bought one before but this does sound a little expensive to me.
Try these ,generally good prices and customer service
wot gpz is it mate as my brothers got **** loads for the gpz9r
GPZ 500 D7 - 2000 model
so not sure they will be compatible.

I’m sure EBC have their own online outlet…
