Yeah,tighten it as hard as possible.My tip is to NOT use one of those screwdrivers where you can swap it to phillips head or flathead i.e. removeable handle.I did and when I was tightening it the handle came off and I put a huge cut strait down the palm of my hand
Affective against compression in an accident but the idea is to make the car more solid,which it definately achieves in the sedan and hatch!! The OH boys have proved this now
