45mm spacer question

synolimit

Ok had to use ARP studs anyways. The Z1 rotors (by the way true weight was 15.04lbs and OEM was 19.42lbs so 4.38lbs diff) I believe are thicker than the OEM rotors and I was only getting about half the treads on the spacer nuts. Now that probably still coulda been ok because the driftworks nuts are double the length of the Z1 spacer nuts. So either way it still shoulda had enough clamp force but I didn't want to risk it.

As for the ARP studs I didn't get what Z1 sells. Those are 12x1.25 thread but way to long. Even though they were going through the hub, rotor and 45mm spacer it still was gonna hit the back of the wheel. So I went with a 12x1.50 thread which was like 1/2" shorter. Of course I got 10 new 12x1.50 acorn nuts and even though there's poke still with these, they don't hit the deep dish of the back of the wheel.
