These extended wheel studs fit on the front hubs of most RWD Nissans, such as the 200SX S14, S15 Silvia and Skyline. (not S13, sorry)
They are 62mm long, (approx 20mm longer than standard ones) so there's extra thread for when you're running spacers.
They're a splined interference fit, so you knock your old ones out and pull these new ones through by winding them in with a wheelnut.
Priced individually, just choose the quantity you want.
When changing wheel studs, don't forget to check and re-torque your wheelnuts after a bit to make sure they have properly seated
