Longer ARP wheel studs on front?
Hey everybody,
I ordered 3.25" ARP wheel studs from Mazdaspeed awhile ago. They're ARP PN 100-7713. Has anybody installed them on the front hubs? The splines don't match, and Mazdaspeed's answer is, 'yeah, just jam 'em in there.' They claim the studs are designed to just push their way in there.
That makes me a little nervous. I like stuff to fit together nicely and not require hydraulic pressure to force their way in.

Agreed, on any car I've ever worked on you have to press in/out the wheel studs. Can be intimidating at first but once you do it a few times it's easy. HarborFreight has a great press that comes in handy for everything from wheel studs, bushings, wheel bearings oh and making a tombstone for a Miata (turns out the base platform width is identical to the tombstone mounting width!)

Thank you for your responses. I'm well aware that studs are pressed in.
What concerns me is that the splines on the studs don't match the splines in the holes on the hubs. To me it's like cross-threading a nut on purpose.

I had the correctly sized ARP studs posted on the forum already, ARP #100-7719 for both front & rear which is listed for the NB Miata. These are only 2.75” OAL if that matters.
and no, they won’t be a looser fit, just easier to get in if you don’t have a real press ...
fwiw it’s the same ARP stud for the rear too

The ones I posted about originally seem to be working just fine.
Also, I bought a press finally.

And I would blame the lug nuts, not the studs. I switched to 949 aluminum nuts, and they've been a big improvement.

you're brave running aluminum lug nuts. i've seen aluminum lug nuts completely rip off the studs on two different cars. i guess they're fine if you replace them often.

the Project Kics lug nuts on my car now are over 10 years old. ran them on my S2k for three years, then sold the car and swap them over to the evo for 7 years. then sold the evo and swap them over to the RX8. best lug nuts i've ever used, i mean the only lug nuts i have used. lol
i cant count how many times they have been torqued but typical race weekend, wheels are swapped or rotated at least 2-3 times. i use a little anti seize and torque them lower, same seat pressure with anti seize.
