If you do the GT2, and you should because you'll love that car, the glow plug will depend on the nitro content you run and altitude your running at. Start with 20% fuel and a medium plug ( O.S. 8), that should get you going fine. Change to the upgraded brake shoes , and when you can get the new shoe type tranny to drop in, do it. The stock tires are pretty much useless except to drift a bit before you change them. Try the Sweep 50 exp tires and you should be good to race or run.
