Our lug nuts use a 17mm socket. This makes changing tires easier and helps protect your wheels from a spinning socket. The open ended design works with standard or extended length wheel studs. The 12mm x 1.5 thread is the same as stock Miata lug nuts.
Advanced Autosports stocks these lug nuts in packages of:
4 lug nuts, enough for 1 wheel
16 lug nuts, enough for 1 car
20 lug nuts, enough for 1 car plus 4 spares (our most popular)
