Welcome to the forum, 'Mark parnell'.I accept a bit of wind noise! However this noise is very loud.
I use a pair of generic steel roof bars with Thule fittings and they make little or no difference to noise levels whatsoever at those speeds.Ive just brought Kia roof bars (from Kia) and at 60/70 MPH they are making a very loud noise! I accept a bit of wind noise! However this noise is very loud. Has anyone got any suggestions pls?
