The Hayabusa calipers are the 6 pods?
Then you could better use ZRX forks and 310 mm Kawa discs. It depends one wat kind of wheels you will use.
I am building something like that after seeing the MickMaguire Tbird overhere.
Mick is using the wheels of the kawa ZRX too but i will use spocked wheels because i find it more classic, specially when the Tbird is black.
The Hayabusa pots are a bit different then Kawa one´s. They use 8mm bolts and the kawa ones are 10 mm to bolt the calipers on the fork.
A spocked TBS wheel is hard to find, a new one is verry exspensive (about 450 exl. taxes euro overhere in Holland, without discs)
And like Dennis said : Not the easy way
