Full set of 20 Aftermarket Shank Type lug nuts.
These 13/16" (21mm) lug nuts are necessary when using 370Z or G37 Factory Sport wheels as the shank goes through the wheel applying the clamping pressure to the washer, not a conical seat. If you do not have these lug nuts you are not getting enough thread engagement holding your sport wheels on which could be a safety hazard.
These lug nuts are one piece unlike the factory lug nuts which have a Stainless Steel Cover over the steel nut which can deform over time and make installation / removal more difficult.
Available in Chrome finish, or Black.
