i have nearly finished a full s14 brake set up on s12 hubs, need long wheel studs , s14 disk redrilled to 4 stud and the calliper will need spacing, i am just getting some spacers made up think they need to be about 11.5mm:)

let us know how you go on, i have the s14 calipers, but with grooved s12 discs, i'd be interested in getting some bigger fronts on there and what about the rears, is there anything we can do to improve those ?

Be worth trying to get the disc redrilled so it can be bolted to the rear of the hub before trying to make spacers

should work the same with the M3 kit then. nice

Yeah but it will be to the PCD of the inner hub bolts which arent the same as the PCD of the wheels me thinks. But if the offset this way isn't an issue then for this method its a damn handy upgrade

Is it hard to swap s13 brakes? I could get the whole seat quite cheap.

s13 discs won't go on without the above difficulties and the calipers are no better

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

I guess then i have no choice but to go z32 up front. Maybe somebody can post up a pic how to fit the z32 (or s14) disk with the caliper on the s12 hub.
But what to do with the back? Are there atleast any decently priced rotors for the back (not 150 pound diamnod black's)?

Rear upgrade would be to use Z31 rear discs, and quite possibly the calipers if they designed for a wider disc.

Z31 rears are about twice as thick because they are vented.
