Need to replace front rotors for a z32 BBK with 13" mustang Cobra rotors, drilled to spec. Bought this car with the z32 kit already on, so I'm not sure of all my options. Rims are 350z 18" Rays Forged Aluminum Track Edition Wheels (staggered).

1.) What are my options for z32 front rotors besides getting Cobra rotors and having them redrilled?

2.) Is it true that a 6th gen OEM rotor will work without much overlap?

3.) I also did some research and found this http://forums.maxima.org/8166686-post2.html , however, the 66.06mm (nissan hub size) to 71.12mm (cobra rotor hub size) hubcentric ring size are not correct (learned the hard way). Anyone know the correct hubcentric ring size (ID/OD) for an 02 hub to a 13" cobra rotor?

Thanks.

 

the stock 6th gen/z33 rotor is 12.6" - it's not a perfect fit

from what I remember you will have to get different adapters for them

there is a group deal on the setup using just the calipers from z32 and utilizing a 12.2 rotor, which will be thicker than stock

hubcentric rings are needed only for some of the aftermarket rims, for the stock - studs will keep rotors in place and once wheel is on - it will settle down properly

the easiest way to check the bore of Cobra rotors would be to take off the wheel and measure it with a caliper
