Some basic parts can still be found here and there, but to be honest, the TC4 should be placed on the shelf, and if you just want a cheaper car to run on parking lots, street, and driveway, get a Traxxas 4-Tec, they are designed for that. For racing, unless your local track has a class that has all other racers in that class using a Traxxas 4-Tec or Tamiya TT-02, they will not be competitive against actual race platforms like XRAY, Awesomatix, Mugen, and Schumacher.
