calipers
 

I have 300zx front calipers, this makes it very easy to lock the front wheels. I was wondering if 300zx rear calipers would fit on a s13?

yes they fit but u have to get the whole ebrake assembly as well, not just the calipers..and of course rotors ect...

You can bolt everything on the rear without the Z32 ebrake assemblys but you WILL NOT have an ebrake correct?:dunno:

To do this, you need the entire assmebly and not 100 percent sure, but I believe you need modified or different ebrake cables. You can also do it without the ebrake, but you still need the z32 hub to mount the rotors and calipers

Is there another alternative to this? something easier or would I be better off getting a big brake kit?

you can go with J30 front brakes and you could even drill the whole out and run them on your 4 lug setup.

its not that hard really..but yea im running j30's on the front

Depends on what you are using the car for. For street or autox, the 300 calipers are all you need. If you want to do road course, they will work with some good rotors and pads, but a BBK would be a good option at that point.
