rear brake upgrade

[bananaface]

Hi all.
I have a hub conversion with 18" spiders all round and lovely 328mm tvr brakes on the front. This always makes me look at the rears and feel a little disappointed. Has anyone upgraded rears and what too that will fit the 5 stud pattern. Also...i got to have those black calipers with the yellow tvr to match the front !! Were they ever fitted to the rears or does the bias go bad ?
Thanks in advance.

yes its a griff, Since the tuscan there was a t350 rr and now the griff.
methinks a profile update is in order.
sorry
