i also posted this over in the Tire and Wheel forum but thought i might be able to get some help here also.

i just got a set of 5Zigen lug nuts for my Volks. But they look too big. Anybody know if 19mm is too big or not? If it matters, they're for my G35

thanx,
chris

 

19mm is not too big, if not it's quite small. Though your thread type may be different. Honda uses a M12 x 1.5mm ... The G35, if I'm not wrong is a M12 x 1.25mm, no compatibility in fitment there.

 

On my last car I had some Versus SS7s made by Rays so I purchased some Rays lug nuts only to find out they didn't fit. I called Mackin and was told Rays makes two different "hole" sizes for their rims 17mm & 19mm.

 

you're correct with the size for the G35. it's just that the GT-C's use their own lug nuts. they're small and use a 12mm allen key
