I have a set of used but excellent Prorack whipsbars as per
http://www.roofbox.co.uk/scripts/rbvehs ... Rov0xog2LN
They have all the keys for the locks and even the box they came in should you want. They hold all standard Thule accessories and the majority of other brands
These were on my old B6 as per the pic running Altura bike racks. (I have checked with the roofbox.co.uk and they will fit B7 RS4's) but I now have an RS4 Avant (Woohoo!) and they are 5cm too short for the roof rails!
You are welcome to view first or ask any questions
