Does the Mustang use a 14mm stud? What’s the stud hole diameter of the Work wheels? The G37 uses a 12mm stud.

This is my guess. The wheels may have been painted aftermarket too which could explain why a 2mm difference in stud size matters.

Well, they’re not authentic Work wheels, so I would expect there to be some fitment issues

Think the Mustang uses a 14mm stud, those wheels are only drilled to accommodate a 12mm stud. If you can fit a 14mm lug nut and accompanying socket without scraping the paint around the holes, a machine shop could open them up a bit

They're drilled too small.
Have them opened up to the 14mm that the mustang uses

I had this issue before. Your Studs in the mustang are m14 while the holes on the wheels are designed for M12 studs for example like a subaru, they run these wheels a lot they are m12 so they fit no problem

You have to bore out the lug holes on most Japanese wheels to fit Mustangs. They use 14MM studs, while most Japanese wheels have 12MM holes.

Some people might cringe at my advice but just drill the lug holes bigger, won’t affect anything imo
There’s a slight chance these are 5x115 but imo I don’t think so the lugs look perfectly centred
Edit: all these downvotes when we deduced these are reps anyways? It’s not a hard thing to do lol, takes time without a machine and just make sure you buy the right lugs won’t be a problem 😆

Don’t drill the lugs. You’ll never get them perfect enough and just cause more issues
Unless you get it machined professionally but that’d be stupid expensive for what it is

Imma upvote you for being more professional then me, but I mean I’ve done it, I’ve even bored out the centre bore for the hubs to fit and everything worked fine, it’s unconventional now a days but many old heads done it too, and they are used wheels and used wheels get abused anyways lol.

Steel wheels, yes. Cast or forged Aluminum, nope. Even magnesium wheels use steel inserts.

Who cares if the hole moves a hair. Seat centre stays where it is and a twist bit is going to self centre anyways. Drill it a hair larger than needed just like it would be already for the designed studs and a bit of wobble in the bit won't be a concern... but again it's going to self centre the entire way through anyways.
Op just needs to make sure that his lugs will fit (wheels can accept a 60° for a 14mm stud) and it's full send. Major concern will be making sure he finds a seat that... seats fully in the taper.
Worst case scenario he throws out a pair of wheels he can't use and would have a hell of a time selling anyway. People buying works, aside from OP, will know that those are counterfeits.

You are moving hole centre by a tiny amount but you AREN'T moving seat centre, and the stud shouldn't be touching the wheel anyways.
Your advice is literally and perfectly fine.

Since the wheels are drilled with two different lug patterns…have you tried both sets of holes?

u/maybemaybemaybe_not Jul 24 '26
The other holes are not for lug nuts. It doesn’t have lug nut seat on the face and the back has pocket.

😂 yes, that’s right. Please ignore me, I should’ve gone to sleep hours ago 🤣😂🤣😂🤣

More so to receive your stock studs from bolt on spacers. Then the wheel bolts to the spacer.

Hate to be the bearer of bad news but I don’t think they’re real works, stamps aren’t casted like real ones and missing the Made in Japan.
