I have a set of Yakima Whispbars that I used to use on my old Mk3 Leon Cupra Hatchback. I just got a Mk4 Leon ST PHEV and I want to change the feet to reuse the bars. I'm seeing on roofbars.co.uk that the Mk3 bars are not compatible with the Mk4, but the Yakima website shows that they are. Just want to get some solid feedback before I spend 30quid on new mounts.
