I'm trying to improve my climbing abilities. So far I'm mostly stock with the exception of the steering servo and controller. I also flipped the bumpers for more clearance. I'm thinking about underdriving the rear and adding some brass portals up front. I'm already one of the most capable rigs in my group. I can use open diffs to get places that others can't get to with locked diffs. So I'm not looking to do anything too crazy. Is there any data on how much each of these mods help when climbing up rocks?
