As SpEEdyBL mentioned you will need truggy wheels with 1/2 offset or wider wheel adapter otherwise your front tires will interfere with your body while steering.
I used truggy arms to avoid this problem.
I posted some videos in
this thread,
this thread and in
this one.
Traction increases considerably but you have to shift some wheight to the front of your buggy to avoid wheelies (Due to the higher rotating mass of truggy tires the tendency to wheelie increases). My conclusion after running my buggy with truggy tires was that my truggy with its longer chassis just handles those tires better and is easyer to drive as it does not loose as much grip on power while steering.
