Seeing that nobody has responded to your question I have a Boxster and ordered and received Lloyd mats thru Pelican Parts. I was initially concerned that the rubber/vinyl mats would slide but instead find that they are a perfect fit even though not attached to the car. Having vinyl/rubber perhaps helps them not slide. They supply plastic clips to attach to the car but could not find anywhere to attach them too.
However with the perfect fit it precludes attachment. Purist might differ!
Hope this helps.
