Hello all, I am just about ready to order my 4" portals, but am not sure about the reduction I want. I was set on 15% reduction as I mainly trail ride with portions of hill climbs, rocks climbs, and occasional mud pits. I plan on mounting 32" Frontline ACP tires. I also have a stage 3 FTGU clutch set up and Alba reflash. Don't want to lose too much top end, but also don't want to be disappointed and not be able to turn 32's. Did not install clutch or reflash yet. Any help would be appreciated.
