I think digital cars are more sensitive to receiving a clean signal through the braids, so guide set up/clean rails/consistent conductivity round the whole track become more important.

I am pretty sure that conductivity is not the issue here. Also when holding the car and lifting the rear axle the motor does not run smoothly at a constant rpm. Same also when running the motor without gear attached to rear axle. No problem when running analog!
