Extended, bull nose, grade 10.9 wheel studs

Do you need stronger and/or longer wheel studs, but you're on a budget? Maybe for track use or wheel spacers? Or maybe none of that, but you just change wheels often? These studs are your solution. They're 10.9 grade studs, with the right knurl and nice and long - 2" of thread (from the hub face), plus a bull nose end for easy and straight lug nut installation. M12x1.5 thread (what all Miatas use). Since they're longer, open-ended lug nuts may be required.

NA6 (1990-1993), NC (2006-2015), and ND (2016+) use a 0.507" knurl on the front and the rear.

NA8 (1994-1997) and NB (1999-2005) use a 0.507" knurl on the front and a 0.579" on the rear.

Sold as a set of four, you will need one set per wheel on an NA, NB or ND, but those goofy NCs need 5 sets per car.

Installation note: it is tempting to use a lug nut to pull these into the hub, but that's a good way to damage the threads or the hub. It's better to press them in, and be absolutely sure they're pressed in straight.
