so I may be getting a chance to pick up some 7 gen gt-s wheels. I know they will ft, but i have read somewhere that a new kind of lug nut will be needed to mount them properly on our gen 4's. can someone let me know what kind of lugs would be needed and possibly what kind of wheel lock would be needed for these? thanks
It's definitely a shorter lug for the 7th Gen rims. You can use the ones you have, but they'll stick out. I can't measure them right now, so maybe someone else here knows the size of them.
They don't sit flush, so it's really just looks and/or preference. Functionally speaking, they're fine.
