Maybe I'll send off a stock rear stud and have them find a duplicate replacement.

 

Are you sure Jon that they are skinnier? Because they use the same lugnuts.

Or do you mean the part before the threads?

 

The notched end that you press into the hub is skinnier, not the threads.

 

just measure it with a caliper. that should be good enough for them to find a replacement.

 

Or there is a cheaper option that I went with about a year and a half ago.

I just had to drill out the knurl a little and popped them in and got the correct lugnuts. all for the cost of a package of one of the evo stud kits.

Here is a couple pics of mine:

 

i had all evo studs on my 1st tib that i crashed at 70mph (spun 180 degrees)-... when all was said and done, the evo studs were still in tact. i'm not saying that the fronts and rears are the same size, but going by sharkracing.com's wheel spacer set i measured it (w/ calipers) and called arp for a custom stud when they informed me that the evo stud was exactly what i was looking for and was almost ready for distribution to dealers.

i also heard hubs should be bored out by a mill not a hand drill. if anything were to keep that bit from spinning true to the hub you could screw up the driveabilty of your car.

 

While updating the links in the approved DIY listings, I notice there were two copies of this thread . . . maybe one from RDT and one from HA? At any rate, they were pretty much the same EXCEPT that the thread I just deleted also had this IMPORTANT NOTE FOR EARLY CARS WITH CAPTIVE ROTORS in there:
