These only fit 3 doors ?
Yes, 'fraid so. Never seen them close up, but if you have a bit of DIY Know how they could probably be cut shaped and adapted to fit a 5dr, maybe fitted using alternative materials. (I don't Know how they are fitted on, imagine screws & tape)I've seen a 3dr wide arch body kit fitted to a 5dr BMW before. These wouldn't be
that hard.

Ohh! P.S. they don't fit with mud flaps, or at least the styled ones.
P.P.S.

If you are handy with a knife or Dremil type object, they could be made to look factory fit with styled flaps too, if you have the patience.
