personally i tried it on both sides... i did not notice a difference at all... there may be some scintific reason for putting it on one side or the other, but having tried both .. i cant say one works better then the other...
the warpspeed chassis is on the left also.. and i havent heard any of them guys complaining it hurt anything...
as far as i am concerend and have seen.. as long as u get all of your weight right on the corners.. there shouldnt be a counter balance issue,,
every shaft drive car and chassis is going to have some sort of tourqu steer.. with the way the motor is mounted it is hard to get rid of it.. all sedans have tourqe from the motor.. but on the others it torq's front to back....not side to side
