Also, in reference to the Pro-Module suspension, according to David Jun of Tamiya USA, he is not sure if the Tamiya Japan released version will have all the necessary hardware to fit it on the TRF415 (the extra spacers and hardware screws) and also he is not sure if the tuned spring will be included as well. The next batch we receive from Tamiya USA might be the last batch that will included all necessary hardware and tuned spring.
