i have managed to lay my hands on a pair of fireblade nissin gold calipers as used on sp1 etc.. now the bolt centres are the same as the '30, but these will not fit without a bracket being made. Is what i am after the same bracket that rick o' can supply me? i have done a quick search but have only founds references for a bracket along with brembo calipers.

what is this bracket likely to be made of aluminum...

Yes, the Rick Oliver bracket is what you want.

Made of aluminium and very nice indeed!

yes contact rick, he can supply you with what you need and yes i belive they are ally
