the ARP lugs are great but if you want to keep the OEM studs here's what you need to do:


under no circumstances let anyone else installing the wheels use an impact gun.

the way you described how you're removing them sounds like you were putting pressure on the stubs beyond the pressure is supposed to be distributed.


its not big deal to use an impact to take off the lugs (1/2 drive impact)
before putting the lugs back on use either some pressure lube or anti-seize
start by hand threading, then you can zip them on with a 3/8 impact if you have one but don't drive them into the wheel once they stop turning.
use torque wrench to tighten them the rest of the way.


I have been doing this and have had ZERO issues with my OEM studs.

Search for my post regarding OEM stud planned obsolescence. A Subaru field engineer told me they are designed to have a limited lifespan. I don't remember what that is off the top of my head.
