northerner the brakets are for a s13, the kit comes with extra spacers but they are not needed on s12, I think they would probably go over the hubs without machining, will check tomorrow for you.
s13eater, they are the 315 kit. dan at db power can get pads now that work with the s14 callipers that optimise the surface area of the big discs as there is some wasted disc with normal s14 pads but still a good upgrade
