    Wheel spacer size with 300zx breaks

    Hi all I have a 300zx break conversion and my rear wheels fit fine but I the standard wheels on the fit only.
    Any idea what mm I need and how do I extend my wheel nuts? Can it be done?

    It depends what standard wheels you have.

    5mm spacer is required if you have facelift wheels without the webbing inside.

    25mm spacer is required if you have facelift wheels with the webbing inside.

    Prefacelift pepperpots....forget it. Its not happening.

    For the 5mm ones, I can recommend the H&R hubcentric spacers. They come with longer studs when new.

    Some people don't both fitting longer studs with the 5mm spacers. Its a borderline decision. I chose to fit longer ones.

    Alternatively, do a search in TechS13 for my name and hubcentric and you'll find a few threads that give details of the studs you need.

    I can't remember the details but I think they are M10 with a 1.25 pitch and a 12.7mm knurl. Can't remember the length but basically 5-10mm longer than the standard ones. Measure from the tip fo the thread to the back of the knurl.

    There you go.

    Just make sure you don't buy ones with too big a knurl/spline. A lot of them are advertised as Nissan/Subaru and have a 14.3mm spline. They are for S14s and won't fit an S13.

    If you find one advertised as having a 13mm spline, that will fit.
