I'm getting closer to having the suspension put on my Z32 and putting my Volk GT-P wheels on and just curious which type of seat the lug nuts use. I'll be digging 2 out later to have tires put on them tomorrow and can see if they're flat or have a taper, but thought I'd ask someone that knew in case they were ball seat or 60 degree cone seat, might be hard to tell with the naked eye.
