Hi all - I thought I posted this last week, but I'll try again. There is a lot of talk on the forums, and I've looked on other sites, but I can't find a definite answer. I have the 12SW calipers and the 300ZX vented rotors, and then got the spacers recommended. What length in studs do I need? Does anyone know a part number, or any info on where to order?

Those spacers don't affect the wheel studs. Goes between the hub and rotor.

I had to get longer studs also - I'll have review to see if I can find any info........

Longer studs are determined by your choice of wheel and how you want them to sit in the fender well if you find you need a spacer to push them outward.

 

The rotor position is only thing that is moved with the z31 rotor spacer for this upgrade. The hub still fits the strut spindle in exactly the same place, and the wheel mount surface (base of the wheel studs) does not move in or out with this mod.

 

Only other "need for longer studs" I can imagine might be the need to get longer 10x1.25 bolts to put that new spacer between the rotor and hub if the spacers didn't come with new longer hardware. The stock ones are much too short to add that 0.663 spacer.
