Question extending hub bolts?? please help.

is there any way to extend the bolts that extend out of the hub?? I got a great deal on some wheels but the lugbolts don't stick out far enough fo sufficient lugnut threading...

is it possible to just take them out and use lugbolts instead of the studs?? please help!!

....something tells me that this is NOT a good idea...and the wheels likely are not the correct fitment.

ok, apparently I can get longer studs... so I'm going to look around and see where I can get them.

BTW, what's the minimum amount of safe lugnut threading??

whoa whoa whoa...

i think you need a 1.25 thread right? (at least, thats the stock size iirc)

dude, you have any websites i can look through? i want to get some new (hopefully, much stronger) studs than stock...

well, i don't care if it's 1.25 or 1.5 since I can get lugnuts anywhere.

I've figured most of it out already.... here's what I know now...

(diameter)x(thread spacing)x(length)

stock is M12x1.25x~42mm length
ARP makes 2 versions of the size we need.
M12x1.5x ~42mm (1.850")
M12x1.5x ~73mm (2.850")

lowest price I found was $15 for a set of 5... need 20, so 4 sets for $60, but that was on a special sale, so more likely they'll cost about $20/pack; retails for $25/pack. these should be MUCH stronger than stock bolts since htey are designed for racing applications.

I'll be buying the extended one that's 2.85" long, and using open ended lugnuts The studs will stick out past my lugnuts by about 3/4" inch, but it's okay, compliments the lack of a centercap on my wheels, and will allow my to run a wider variety of wheels should I feel like it later on since I can make my own spacers.

another company that makes wheel studs is Skunk2, but they only sell in sets of 16 for $80, retails at 100 i think... too much, and I trust ARP more than skunk2.

I'm getting them installed at my local mechanics who sponsors me and my friend. gonna put on the rear wheels w/ no spacers since they fit, then one front wheel w/ 3-4 turn thread engagement (that's why I need longer studs) and the spare tire on the other front. then I'm having it flatbed towed to the shop. there's no way I want to risk damaging my 13lb forged wheels driving w/ imporperly installed lugnuts. =)

hope this helped.

thanks Luke, sadly, w a 10mm spacer my front will only engage MAYBE 3 turns max... a/ the minimum 8mm spacer I think it can reach 4 turns...

I don't even trust using 6turns... so I'm going to pick up these wheel studs and I'll jsut deal with the studs sticking out. =)

I just did the tech drawing for my spacer design.. now I'm off to buy a chunk of aluminum and off to the machine shop I go lalala

hmm... i did some searching, and the only similar size i could find was "GM: Camaro/Firebird/Corvette, late GM, 12mm x 1.5 thread, 2 1/2 in. long, .509 in. knurl diameter, wheel studs"

can you share teh website where you found the rest of their sizes? i dont think then make the stock 1.25 size diameter

1.25 isn't a diameter.... it's the thread pattern. if your'e using longer studs, the stock closed end bolts won't fit, so you'll need open ended nuts, so it won't matter. jsut get nuts that match the stud.

ARP 100-7712 i think is the part number for the M12x1.5 2.85" long studs. same as the honda fitments

BTW, 1.5 thread is a stronger thread pattern

I got a set of longer wheel studs with my H&R 5mm spacers - still 1.25 pitch. I'm looking to get another set now for spares as I really can't use the shorter studs now.

Nismo (nissan performance) makes 1.25 pitch longer wheel studs. I have them currently, but they are quite a bit more than the ARP ones. I would have just gone with the ARP ones had I known at the time, since I ended up getting new lugnuts anyways.
