Andrew be careful when you're trying this bro, the reason lug studs have so many threads on them is so that the 80ft/lb. of torque necessary to hold the lugs down can be distributed in a more linear fashion among them.

Start messing with this (and only getting four threads deep) and you're taking a serious risk of losing a wheel while cornering. "Safe" is always a relative term bro.

MikeGSR has some good advice.

...saw your car out at Luke's this weekend btw, your secret is safe with me.
