For anyone using spacers, did you get extended studs? If so do you have apart number?
I have some spacers for the rear and am concerned about the reduction of thread engaging the nut. Also looking for quality studs as 140 ft/lbs torque is pretty high; would hate to break them at high speed.
 
I have used 5mm with Enkei wheels with stock studs. I didn't like that at all. My thread engagement was half of what it was without the spacer. I don't think I would do more than 3mm on stock studs. Another alaternative would be to use extended lug nuts, such as what Gorilla offers. I bought them, but they didn't fit through the holes on the Enkei wheels. However, they do fit my Apex wheels and I plan on using them with the same 5mm spacers. They allow for esentially the same thread engagement as no spacer.
 
Another question: for OE wheels do the spacers need the raised bore rim, or can they be completely flat? I'm thinking 6mm spacers...
 
I used flat. But I also used concentric rings on the wheels. Technically, if you have a spacer with a lip that matches the wheel bore, you wouldn't need the rings.

Studs are the same as 6th Gen Camaro. Can't get better than ARP.
 
5-6mm is about max you want to run. There are hubcentric slip on spacers in Ebay cheap.

But I've also used Ebay 15mm bolt on hubcentric spacers with no issue on my old 4BW.

Do you know which lugs you'd be looking to use? And if they'd work on OEM wheels? 325 rears seems to be the easiest option for a all season tire and the extended lugs might be the way to go without having to swap studs.

Otherwise ARP wheel studs 100-7736 seems to be the closest to providing just a bit more thread engagement. At 2.7" but that's almost 1/2" more than stock. Don't know if factory lugs would fit on the extra 1/4" on top of a 6mm spacer.

Any wheel and lug gurus cause this is all new to me.

This. 5-6mm should be max on stock lugs.

5mm is too much. I had that on my atsv and it resulted in half the thread engagement on the studs. I would not recommend it. Discount tire would not put these wheels back on with these spacers on if they ever take them off.

5mm is safe, Discount has silly rules.
