I have one per side on my 4/4 sport - no problems in 10 years with them I think they look good but also are a visual reminder to keep feet clear of the running boards and encourage lifting feet that bit higher - so fewer scuffs. Even if someone does stand on them - and I`ve only come across it a couple of times- it stops the running board being stood on and provides a bit of protection (they would probably have stood on the wing anyway!).
