!!!+3 in front has less steering so it make you fell like you have more rear grip.-3 rear would give you more traction if they had it. the best way to get rear traction it to put your weight higher and to the rear(but it not the best thing to do this truck jumps bad this is why you see almost all set up with battery in front./// (on power traction only!!! not in trun) if i where you this is what i would do/// start with anti squat at 0/// add toe in till you get the grip you want. once you get it where you can handle it getting on the straightaway try driving hard in to a off power turn !!!note!!! you should have a push now what you haft to do is add anti squat this will let the truck rotate more going in to the turn!!!one more note!!! anti squat also add more on power traction so once you add it you can take out some toe. try to keep your toe in low as possible (to much can take speed form the the truck) and to much anti squat can cuz the truck to spin out going in to turn.
