i was thinking about upgrading my front disc brakes, was wondering whats the best ones i can fit into stock 16" alloy wheels

 

You need a bigger wheel to put bigger brakes on.

To upgrade your stock setup, put a slotted rotor on and get an agressive pad.

 

Yup, i'd put slotted rotors and then some better brake pads. I plan to do that sometime after i get 16" rota subzero's.

Good luck!

 

Not exactly. The 300zx set up uses 16" wheels. The problem is caliper clearance. SO, if you get the 300zx rotors, pads, and calipers you can use 300zx wheels.

Maybe you can use the calipers of an M45 or Q45 (or whatever it is). They have twin piston calipers what clear many 16" wheels....stock I'm not certin. http://forums.maxima.org/showthread.php?t=382530 He uses Q45 calipers with a 16" wheel.

But IMO you are better off with performance pads, quality blank rotors, hi temp fluid, and SS lines.
