Agree on the spacers and ARP studs. This will end up being a winter purchase for next year. The 2 wheels I mentioned above are the cheapest quality track wheels I have found. Specz can use anything 18x10 and no less than 18.5 lbs unless you go with the PF01's which are the recommended wheel.
with 285's can you run that with the stock fender liners and fenders on the front? How much camber are you running?
