HELP Extended Wheel Stud Confusion

[DSPbuilt]

So I am in the process of trying to order new extended wheel studs. The stockers are too short for the aluminum wheels. I searched here and found a couple threads saying to use ARP 100-7708 which have a knurl size of .509. I have also been reading threads about doing corvette front brakes and others and everyone complains that when using a .509 knurl you risk cracking the hub..
So, I a little look on rock auto and the DORMAN parts show that the stock replacement is a 12.8mm (0.503937in). There isn't too many option in that size.
What are you guys running and what have you had luck with?
Do I just risk it with ARP and slowly press them in, not using a a nut and impact like most people do?

Wouldn't those be loose with only .500 knurl?

the stock knurl size of 12.73mm works out to .5011, the hole in the axle flange is .486 so the .500 knurl will not be loose

Thats what I used on my LS1 brake swap.

0.504 knurl and it seemed a little big. They pressed in hard.

0.509 in my experience would be too big.

I prefer to not be like most people either - I use a BFH.



Kidding aside, knock out an old one and measure it with a caliper. Then head off to the local parts store and wander into the their stud aisle with your caliper and pick a winner.

When I was running Pontiac snowflakes I needed longer studs. I used the Dorman studs. EZPZ.
