Tire's are a big guess, Proline Electrons, Jconcepts Dirt Webs or AKA Chainlinks seem to be the go to nowadays. The compound really depends on the clay they use and how wet the keep it. Most guys run a clay compound like the Proline MC but here at our indoor we have to run black/M4/super/ultra soft compounds. You won't know until you can run the track but maybe start with the clay compound.

Motor builder? With brushless most guys just buy a good stock 17.5 motor like the Trinity D4. If you're running stock 17.5 or superstock 13.5 most people frown on tinkering with the motor. I'd just get a decent brushless and be done with it. You can always change the timing with the speed control if you need more pop so long as you're not in a stock class.

Springs, most guys are getting the Kyosho Gold Springs for this truck.
