hey guys i just did some reseach and found that a couple ppl have said that the r32 calipers and rotors fits on the s14 without any mods…but there was 1 or 2 sites that said that some modification are need…i;m about to buy some r32 brakes and calipers off allen but we do not know if the spindals on the s14 kouki will work …help us out plz thx … flaming allowed 
i hear your pain. I’m in the same boat tryin to figure out what i need for 5 bolt conversion /z32. Confilicting information astounds me.
Some are saying i need the whole assembly for the 5 lug first, then the z32 conversion. Some are saying i just need the 5 lug hub and the z32 rotors/pads/etc.
according to http://importnut.net/300zxbrakeswap.htm for the s14 all you need is the 5 hub, so i’m gonna go 5 lug hub + z32 brakes. As for your r32 brakes, i’m sure they will fit, but if am to understand what i have read, the z32 brakes are better.
then there is this little gem http://www.240sxforums.com/forums/showthread.php?t=67694&highlight=Evo+Brakes i’m scouring for decent priced components for this right now, as it seems like a better upgrade. Its not the evo calipers, but the sti. Read thru to get the best idea.
if anyone knows of anyone with the sti brakes i would like to know.
thx for the help man…dont worry we will figure this out together
