I noticed that the Fury is not on their list of approved SCT. Having raced a Fury in both Mod and Stock classes I can tell you they have great balance and jump flat but the stock shocks are the pits. Verify that they'll let you race in the class. If they do, definitely get a new set of Fury wheels and use either the Losi Eclipse tires on the Kyosho ones Dreadstar suggested.
I've found that the Arrma motors burn up quickly so consider getting a spare or swapping out to the HPI or Traxxas stock brushed SCT motor.
You might also get a roll of fiberglass sheet rock tape, a couple of tubes of Shoe Goo, some plastic paint scrapers in a variety of widths and painters rubber gloves. Reinforce the body with a layer of sheet rock tape and Shoe Goo. It'll increase the weight of your rig a little but it'll increase the durability of the body by a ton!
