i have cut every other tooth on my xray front and rear belt on the evo2 kit it was noticable with stock but should not be done with the rear belt it will strip to easy i ran the front cut belt for at least 3 months i replaced it when it was tweeked or bent side ways and flipped over twice in one day but it never broke running 19 turn
for stock it is noticable and worth cutting the front belt but i would not do it with 19t or mod and i would cut the pully this time
alex lopez runs super thin belts front and back that were saved down to kevlar and were super flexable when i spun his drive train you could see how free it was and no one can say he is slow
but when he put a 19t he broke it
