ARP WHEEL STUD KITS NOW AVAILABLE

[Optimum Performance]

We have our version of the wheel stud kits available directly from our website HERE

These are complete with the Factory One Time Use Hardware to install them and very detailed printed instructions that includes torque specs.

This will allow you safely run up to a 20mm wheel spacer. We will also have complete Hub Kits ready to ship this week as well.

We also offer custom hub centric billet aluminum spacers in custom sizes.

Are these 14mm like oem or 1/2" like '11-'14?

I am extremely interested! Can you send me a quote for the studs and 15mm spacers? Thanks

Can I get a 7mm spacer and a stud length that will still allow me to use acorn style lug nuts?

These are 1/2" but I should have more info on a 14mm stud solution tomorrow.

15mm on all 4 I assume, I will price the material and PM you, I'll try to get you an answer by Monday night.

You will be the first to know sir I need to dry fit everything and get some measurements. Are the acorn style you have similar in length to the factory ones?

The are the normal spine lug nut but very similar to the stock ones yes

 

[XLR8EDMUSTANG]

Yes, 15mm on all 4 corners. Do you have a black lug nut option? Thanks.

Pictures of our 14mm extended stud with one factory stud in place to demonstrate the .800" (20mm) difference. We would like to thank UPS for delaying our post until 10:30PM EST. We will have these as assembled hubs up on our site soon. We are working on a true 3" extended stud but some of that is out of our control. The factory stud is approx. 1.500" from the hub flange our stud extends to 2.300" above. This provides roughly .500" (12mm) of usable spacer thread surface.

can you post a comparison of the stock 14mm vs. extended 14mm bolt heads? i want to replace the studs that came with my adapter (mild steel + heat vs. titanium is a losing battle!), but the adapter holes are quite small (stock heads too big, ditto on the 1/2x20 ARP studs i had laying around).

i'll definitely pick up a set of the true 3" 14mm studs for my rear hubs when they're available, too.

We don't like the adapter design. We have spacers available in several dimensions to work with our stud. They are located by the hub, and in turn locate the wheel. Our extended studs sandwhich the entire assembly together so they are less prone to failure and after 1-2 heat cycles hold torque. Nothing moves around and even with the different growth rates of the hub, rotor, spacer and wheel the assembly has suffucient stretch to maintain a torque setting.

The picture is our first generation 14mm extended stud on the left, the factory 14mm stud in the middle, and our ARP 1/2 stud on the right. Don't ask me to reveal any more secrets

i have no choice but to use an adapter - i need almost 1.5" to run a square 18x12/335 setup without strut interference ;)

.. that said, i've been running the same adapters without issue on my 18x11/315 setup for over a season and DD'ing. no cracking (yet), but i'm definitely keeping my eye on those big blocks of aluminum

still can't really tell if the bolt head is smaller on your studs vs. stock - we can take it offline, and i can take some measurements of my setup for you to confirm if they'll work or not.

Oooh - will you have those extended 14mm available soon? I'm running the ARP ones now w/20mm spacer and then are a lot longer than necessary.

UPDATE ON 14MM MID-LENGTH STUD KITS

We have the 14mm stud kits close to release (enough inventory to assemlble kits as well has complete hub assemblies) This stud is long enough to safely run atleast a 19mm spacer (all we had on hand) and have full thread engagement. Any spacer above 7mm will allow you to run OEM lugnuts on factory wheels without bottoming out.

We will supply the studs with bulge seat open ended lugs until we can line up some of the other lug nut manufacturers (i.e. they don't call back) Even if you plan to use other nuts, we know our supplied lugnuts will let you drive your car when complete. We have no way to verify fitment between different wheel manufacturers and lug nut designs.

The hub kits will be available as well. We are working to get everything on the website but PM is still good.

Our spacers are ready to roll out as well, keeping mind any spacer under about 12mm will not be have a lip to be wheel centric, the hub sticks out to do that so it will be a flat spacer. If you have wheels with a larger than 70.5 OE hub size, rings can be supplied.

We also will be releasing our wheel spacers with an optional integrated dust cap.

Pricing for Front 14mm Stud Kit $119.95
Rear is 14mm Stud Kit 119.95
Front and Rear $229.95
Front Hub Kits $309.95
Rear Hub Kits $319.95

14mm studs are about twice the cost of 1/2" stud.

Our ARP 1/2" Hub Kits will be $279.95 and $299.95 F/R.

So are you saying if I buy your 8mm spacers and 14mm lugs I will be able to use my acorn splined lug nuts?

Any option to get the spacers in black?

Yes and maybe on the black but you could just paint them.
