stock studs are good up to 10mm its been provenWell I used 15mm H&R spacers. U have to buy spacers with extented bolts. Once you go beyond 5mm spacers its a hazard. Then u have to line up the spacers then cut off the the oem bolts (not completly) and ur spacers should come with some special nuts to fit on your old bolts. And yeah aftermarket tuner lugs do fit. I've got rays on mine
same same smilez:beerchug:. well my fronts are h&r but my rear are no name and you run the risk of vibrations at hi speeds. make sure the spacers are hub centric makes sure they balanced on the hub perfectly most name brand spacers are. look for h&r spacers light and durableUsing 25mm no name spacers here with no problems. 1.5" drop though.
