hey guy's I have a simple question that's alway's had me wondering. what the difference in running the servo at and angle(which I've alway done) to running it flat. What the pro's and con's of each. I know running it flat will produce bump steer( what is this excatly)

I run on a very technical track . 6' lanes i belive it is 96x36(3 roll wide and about the full lenght of a gym?? with non forgiving boards.

the car I run is a corally sp12x just gone to the L4 front suspension. presently runny a monster stock motor. if anyone have any info on setup for thie car also would also be greatly appreciated.
