lug nuts yes
studs no unless you're running spacers
Spacers for brake clearance? leaning no, because the design that the wheel copies, the Volk Racing TE37, clears pretty much anything. However, they may have changed the design due to their manufacturing process (clearly not forged)
EDIT:
According to this thread, it will not clear brakes without spacer
