As the title states, I'm planning on going to a 39" wide Pro stance on my '11 Assault. SPI '11-12' Pro arms and Evol shocks. I've done a lot of reading on the subject and found a couple guys say that the Assault sits higher in the front end than a Pro. Besides going narrower, am I messing with the geometry of the sled by potentially lowering the front of it? Can't seem to find any facts about this.
