A couple of things:
1st: are the calipers 26mm or 39mm?
2nd: are shims/clips included?
3rd: have the calipers been rebuilt?
4th: How many miles on them?
5th: are they painted/powder coated?
6th: do you have the conversion lines? ( stock s14 lines won't work even if they are steel braided)
7th: new or used rotors? what kind.
Thanks
