Look at ebay (yeah I hate them too), The fitment of the standard discs is the best look for Brembo or Grimeca makes as they are the standard fitment. Most on ebay go for less than £200 for the pair.
These are the same as yours:
YAMAHA
FZR 750 Genesis 87
FZR 1000 Genesis 87-88
FZR 1000 EX UP 89-90
FZR 1000 EX UP 91-93
XJR 1200 95-98
XJR 1300 (5EA1/5EA7) (320mm front discs) (Brembo calipers) 98-99
(YZF750 and 94/95 FZR1000 EXUP can be exchanged with each other or any of these discs fitted)
try allbikes, abe in greenwich, if just disc warped they might be able to use your carrier etc, save ya some cash, if not might do ya a deal or a pr or 1.
Thanks for reminding me John, I keep forgetting about those guys, must pop over sometime and see what they can do for the Gixxer, it’s about time I upgraded mine, they make/supply stuff to order don’t they?
I’ve got Black Shadow discs on my ZX6R. They were £180 for a set of fronts and only £20 for the rear one. They’re excellent and with the 4 pots I’ve got on, they do the job of stopping rather well.
Got some coming which have come from a Leverda, from what I gathered they have seen very little mileage so looking forward to getting them fitted next week. :D:D
