Harder clutch springs

[Eric GSX1400K3]

Indeed, price is a good point if they fit

I'll take my clutch cover off and get to a spring, to see if they can confirm dimensions.

I can't see them being different in size, but thats me and my wishful thinking 

remember its not the size, it's the number of coils and wire diameter that makes them stiffer (or 'harder'). The overall dimensions will be the same, as they have to fit in the same spot, so you'd need to count the coils and check the wire diameter on the Hayabusa springs

True, what i meant by dimensions is that if the Hayabusa springs for some reason have a larger overall diameter or length at rest, that means that they won't fit in the GSX clutch cover
