Don't have my kit yet (out of stock - Amain) but would like to know what would be the best diff and shock set-up...have no plans of racing.....kit would be a project with my daughter. My ECS/BL motor combo would be the SP SA Ver2 with SA Ver2 5.5R (550 motor) and 5000mah 3S1P 11.1V 40C hard case Lipo battery (which I know may have to modify the kit for it to fit).

Thanks for the quick response.
