Not much needed really. Only a couple of things I'd do to it:
1. B44 rear hub barriers, outer bearing and crush tube.
2. New shock caps with bleeder screw.
3. RPM, JConcepts or Losi ball cups.
4. Trishbits or Ghea front bulkhead.
5. front wing
6. Large rear wing
That's about it really along with a couple of strips of lead weight to balance the whole thing.
