I know this sounds simple, but I never really thought about this before. What options do I have when replacing studs/nuts. I think mine were overtightened with an impact wrech, and I've broken a couple, so I'm gonna replace 'em all. What's out there other than OE? What's good? What brand?

 

... these are just one of those wear items that take a lil longer to wear out

Just pickup new lug bolts from the dealer and maybe checkout the lug nut package found at SLP.

I'm running the extra long lug bolts used for racing that are available from GM.

 

I would just go to the local parts store and pick some up. Any brand will last forever if they don't get overtightened(and you don't run slicks with a bunch of power).
