In my situation, I have a s14 240 sx w/ stock calipers and rotors. I have NA 300zx 11" rotors that I want to put on. The problem is, my calipers won't clear the rotors. A friend of mine told me that 4th gen maxima calipers bolted onto my car will allow me to use those 11" rotors. He is uncertain whether they are the maxima calipers or another Nissan model's calipers (Sentra Spec-V, etc.)

I have an idea that it would be maxima calipers, because he is using the same rotors on his 240sx with single piston calipers, thus ruling out z32 calipers and maybe suggesting maxima calipers. Any input is welcome!

 

Your post is really confusing but here is what I got out of it: You have a 240SX and you have 300zx brake rotors and want to know what calipers to use on that car with 300zx rotors.

300zx calipers... The End.
