yea i ran s14 calipers with s12 disk before which was gd but just thought i would go for the bigger disks which i thought i would need to mount the s14 callipers onto brackets but when i went for a test fit i found that the s14 disks just missed the inside of the s14 calipers so happy days.
Another thing i had to do is i got a mate to machine the hub down a bit, from being more square i got it taken down so it was more like the s13 ones, rounder. The s14 disk now sits over
With the rears i didn't look into any brake swap... didnt want mess with the hand brake mechanism. I rebuilt the caliper and put some new disks and pads in. I now belive the s14 runs the same type of rear brake set up as the s12... o well think there should be enough stopping power now lol
