Hi Gareth.
Thanks for the reply! I would be keen to find some front to back permanently fixed rails but an alternative would be some decent removable side to side roof rack bars as I will only really be using it a couple times a year and mainly to secure a roof box for skis and luggage.
It would make sense to find a good pair of removable bars that aren't likely to ruin the paint work on the roof eveytime they are used over drilling holes in the roof! 🤦♂️😩
Was hoping someone could recommend a decent pair that won't cause damage when they are clamped to the roof.
