Last time I drove the Challenger I heard something small and metallic fall off the car. I was under the car tonight looking for anything loose when I noticed the LCA bumpers are very close to the frame. They are only about 1/4" from the frame and have come into contact with it. How close are your bumpers to the frame. I think I may want to raise the front end 1/2". I'm way lower then the factory spec but the factory spec would have put the front end WAY up in the air. I like the stance now but don't want that bumper hitting the frame. When I go over larger bumps, I've got a rattle in the front end. I wonder if these are related?
