Hi Chris, I did a post about coil shocks, I'm new to the coil world and curious how you figure out what size you need, is it about wieght? I'm still on the drawing board, I'm building a race willys pickup to run in the northwest offroad racing circut. it is a all tube frame so my opitons are wide open, I'm going to use trail arms like the desert racers in the rear and ladder bar fronts like a bronco. so should I go with 2.0? 2.5? or 3.0? thanks Dan
