Wheel stud size??

[Zak's Z]

Anyone know the size or part number for the wheel studs? Im taking the rotors in to get the hub removed and I want to swap out the old, stretched, mangled wheel studs.

Thanks!

The part number is 40222-22001 Bolt-Hub Road Wheel.

I want to "max out" the tire width on my '72 and with the 15" Mitsubishi wheels that I intend to use (see best photo I have at work from a Vintage GP parade lap at Mid-Ohio - coming off the loop leading into the Keyhole), that sends me to 225/50-15 tires. However, the offset of the wheels means that I need to use a 1/2" spacer on the front hubs to keep the inside wall from rubbing on the strut. Doing so leaves only about 5 threads for the wheel nuts to grip on and that isn't enough to make me comfortable. Is there a general rule about that? I torque my wheel nuts to 65 ft-lb.

Are there longer M12x1.25 studs available that would work in the 240Z front hub? I figure that I need about 1/4 - 1/2" more than what the OEM ones have.

Also, these are splined and press fit into the hub, are they not? I assume they can be pressed out?
