What are wheel studs?
Wheel studs are threaded fasteners that are pressed into the wheel hubs, along with lug nuts they help secure the wheels to the vehicle.

just a suggested tweak to the arp specs, where it says :" Notes Designed to fit Subura WRX applications. Will fit untrimmed under stock 1st gen FX center caps with 20mm spacers. you should add to the end of that "and stock or open ended lug nuts" because they won't fit with 20mm spacers and most aftermarket closed lugnuts. I'll remove this post after

Just measured the OEM studs. The front studs are longer then the rear ones, because the front hub is thicker then the rear.

Front
Thread Length: 26mm

Rear
Thread Length: 23mm
