wheels will be your choice, and as far as clearance goes, just keep the offset low enough to avoid getting the inner lip of the wheel too close to the strut. I really cant give you too much information wheel wise, because I dont know enough about what style you want, etc.also, you never know what will clear the upgraded brakes until you actually test fit them, unfortunately the(300zx) bigger brake calipers have spoke clearance issues, even on 18" wheels. a staggered setup is good if you have a lot of oversteer, which is exactly what drifting is, so I wouldnt recoment running a staggered setup on a drift car.-chet
