I seem to remember seeing pics like this - it may have been Skyline calipers, BTW.
Anyhow, there's likely some fabrication involved - ie, creating an adapter bracket. Unless you're quite skilled with machine work and brake systems, I'd leave it be - something goes wrong with the brakes, and you're SOL.

Ok, both the 300ZX and the RX-7 have Sumitomo brake calipers, so for the front calipers its pointless to "upgrade", if thats what YOU want to call it, the front calipers on the 7. The rears would work, almost a direct bolt on I heard! I actually thought about it also.

I have upclose pics of an FD in japan with skyline brakes and wheels, so it is definitely do-able.
The thought has crossed my mind but now I can get Porsche (made by brembo I believe) 6-piston calipers for a pretty good price so I'm gonna shoot for those instead. Now I just gotta find out how much work and money is involved.
Knifeboy- why don't you ise the 8 piston from the Audi RS6?? hehe
Cuz I don't know anything about them or anyone who can get me those for cheap. The Porsche ones on the other hand I can get pretty cheap. And by cheap I'm talking $400CAN. Besides the 6 piston calipers are pretty big, meaning I'll have to buy some larger (17" or 18") wheels to fit over them.
Guys just so you know, bolting on bigger calipers doesn't always give you any better braking force. There are piston diameters of the master cyl, calipers, etc that all come into play. Bigger isn't better if it isn't engineered.
I don't know why the blanket statement "300ZX rotors suck" was made. Figure the 300ZX weighs in at 3200-3400lbs, the FD weighs 2750-2900 lbs stock for stock. A "sucky" brake rotor on one car might be a good one on another.
I bet those awesome go-kart brakes work for crap on a FD.
Project CYM, ground up rebuild.
Winner, Best 3rd Gen SS16!
The 93-96 300ZX used 4-piston iron calipers (not aluminum = heavy) and had 11" rotors up front. The stock FD brakes are aluminum 4-piston calipers with 11.5" rotors. Some upgrade. The rears did use 11.7" rotors with 2-piston iron calipers. This most likely does not represent an increase in performance over the stock FD rears of 11.5" rotors.
BTW, upgrading the rears without upgrading the fronts may result in a braking imbalance. It may actually result in longer stops as the ABS may be made less effective.
i helped a friend do the brakes on his Z before. they are really beefy in size, but everything felt heavy. if you swap calipers and all then you can even get the little drum brake shoes that are used to hold the rotor(inside of the rotor so they are actually shoes) with the parking brake on. now that would just be cool, not really. i dont think its worth the hassle. if you have to do it, go really big. im sure most of our calipers are just in need of a major rebuild.
question though. if we take off the calipers and take them to a machinest, cant they just make the piston area larger and then we would just find a piston that would work in that area. possibly just have the machinest make something else. it would be a true hybrid brake upgrade.
