Adrian....You will be surprized on how fast the car is with 4 cells and the 19 turn. I ran my car a couple times like this last year on carpet and its very quick. I have never raced on 6 cells so I dont know how fast it is but its fun with the 19t. I would assume that the washers raise the pod up some. I know that some times they use washers only in the front for some rake in the T bar but I dont really know what all that does. Im sure some of the other 12th scale vets will help you out on that.
PS.....Dont listen to anything that Dave "Tiger" Arnold has to say as he does not know anything.....unless you are asking how to putt from the rough
