Okay another suspension question for @cletus. Is there a minimum amount of arch required for a leaf spring? I've measured the Fairmont, if I lower it 40mm it'll even up the guard gap, leave the structure of the vehicle about 110mm from the ground and should give about 50mm between the unmodified bump stops and the diff. I'll get an extra over load leaf fitted but the springs will be fairly flat, I'm hoping fitting an extra leaf will mitigate this. Am I likely to run into any other issues? Couldn't see anything in the Virm.
