You are going to need 18" rims although some 17" might fit.
If building on a S13 you will need to drill the discs, or mount the S14 5bolt conversion (like i did).

First, loosen the front wheel bolts/nuts, jack up the car and support it with axle stands:


If you have spacers undo these too: (have someone step on your brakes for this)


Now first remove the calipers and put it aside, but do not disconnect the hydraulic line otherwise you will need to bleed the whole system.

I usually use a screwdriver through the mounting hole behind the ARB


Remove the brake disc and grind away the edge of the dust plate:



Fit the new brake disc and check nothing touches the disc:


Here comes a the most difficult part.. You will have to drill the holes for the caliper bolts from 12mm to 14mm, the steel of the hub is made from is very strong, be prepared to take it to a machine shop or grind your drill a few times.
If you have ABS, put some tape over the sensor or it will be jammed with bits of metal from the drilling proces!!!


Fit the 350Z caliper: The bolts used are: 14x1.5mm 40mm long grade 12.9 (10.9 are also applicable).

The bolts can protrude about 5mm but i made them exactly on the length i needed:


Now fit the brake disc and caliper (without pads and hardware) and check that the disc is exactly in the centre of the calipers:

The calipers should be torqued to 151-152Nm (15.4-15.5Kg-m, 111.4-112.1ft-lb).

Now place the brake pads, pins, cross spring and clips, apply some copperpaste to the back and the sides (when mounted upper and lower edge) of the brake pads:


Now attach the hydraulic line, bleed the brakes and youre done

If you are using new brake pads be sure to follow the break-in procedure.

Before: 280x30mm disc, Z32 brake calipers


After: 324x30mm disc, Z33 brake calipers
