I did assemble the belt before hand and checked resistance then decided to do this, originally i was going to do every 3rd tooth but after looking at it i decided every 4th would be better. After cutting every fourth tooth off it did seem to have a slightly less resistance.
If i wasnt trying to get away with running a 540 set-up i wouldn't have done it.
my trackstart o-rings showed up today so i can finish my shocks and now im just waiting on a front sway bar (i know i can make one, but id rather not) and my body from my awesome painter.
