I fitted wind deflectors last August – couldn’t get the deflectors Joss suggested so bought these
They are more fiddly to fit – need to be lined up carefully before peeling off paper and sticking – but they have been great – no issues at speed – no sign of them coming adrift – just ensure it is a dry and reasonably warm day when applying.
Hope this helps if any of you have difficulty sourcing the other style – I will post a picture of them fitted to my car – I have done this previously – way back in August.
