4 cell racing, though unlikely, should level out the playing field some. Im sure we will see people goin to extremes with their batteries, but it should in theory make it more fun for the average budget racer who wants to run mod or whatever.
Now 4 cell stock......will be like watching tspec cars...
edit: I really think that a 4 cell TC would run somethin close to the same pace as a 6 cell too....
