As far as the TL01 Rally department Ivr got you covered. If you want to go with Tamiya suspension conponents I would recomend the oil filled shocks for the TG-10. Unscrew the Shock end 1 turn. Yhe best motor for the Rally car will be a P2k Paradox 2000 geared at 19. Make sure to run the lightend drive shaft!! If you want to be super dailed and truely rally it Run at water proof speed control and run the white bushings in the hubs to reduce weight and rust!
