The TRF (Tamiya Racing Factory) 419X is the pinnacle touring car race machine from Tamiya's top tier designers. It is a vehicle that can be raced at your local track or at official Tamiya TCS races. This variant of the TRF419X (original Item: 42301) gives the hi-spec racing chassis kit a boost, with new thickness upper (carbon fiber) and lower (aluminum) deck parts included in the kit to further enhance its performance on carpet and other high-grip surfaces. The rest of the kits' features remain the same as the regular 419X.
