Extended Studs - Knurl diameter?

[xcoldr1cex]

Looking to put on some extended studs so I can accommodate spacers safely.

i've only really found
http://store.ichibausa.com/mazda2.html

I was wondering if the ARP studs that fit miata's (and protege's) will fit the ms3 - they have two different knurl diameters .577 and .509 inches. not sure what ours is. Does anyone know what the MS3 knurl diameter is?

I know we are:
Thread size: 12x1.5
Hub bore: 67.1
Lug pattern: 5x114.3
Length: ?

I think H&R makes a whole kit with spacers and studs.. could be mistaken though

I used the ichibausa studs. I was having the same problem as you finding a size to fit. I think there is a ARP studs that will fit bu the knurl is different then stock. I have both sets, currently the ichiba studs are installed and working fine.
