    Hi Guys.
    So, im needing to go a longer stud on the rear + 30 mm
    I believe standard stud length is 41.5 under head length?
    and depending where you read the knurl diameter is 12.83 or 13 mm?
    what i cant find is the knurl length, can anyone confirm the above and also knurl length?

    Also, if anyone know of a stud long enough, please point me in the right direction, the only ones i can find that are 300zx specific will not be long enough.

    I dont mind changing thread pitch if need be, but would rather stay metric.

    Stud length is 47mm and the head is 3mm, there is 29mm of thread and I can't help you with the knurl diameter because you have to have a brand new one to know that.

    You want to use a stud that is 30mm longer ? :eek: you are a very brave man

    Thanks for that.
    So that 47mm is under head length?

    Yep, 30mm longer, I hope you don’t think I need them because I want to use a 30mm thick wheel spacer? o_O

    IB ?????

    If you're going to use a 30mm spacer, you should use a bolt on spacer that has its own studs.

    Na, ANDRA rules about wheel studs is that they need to protrude past the rim face by at least the diameter of the stud.
    So more future proofing really
