I have a 2012 3.7l and I'm planning on supercharging it in the near future. However I would first like to upgrade the suspension so that it can put down all that extra power. American muscle has a project car in which they ended up putting an aluminum crankshaft, J&M rear lower control arms and a JPC racing adjustable upper control arm. Is this a good setup for the money or is American Muscle just trying to sell these products. Also are there any bolt on mods that y'all think are absolutely neccesary for a supercharged mustang? Thanks in advance!
