I fitted the Whispbars on Saturday morning. They were much easier to fit than the Thule bars. I found it awkward to position the feet on the Thule bars in exactly the right spot so that they dropped on to the fixing points. When fitting the Whispbars you preset the length of the bars and the feet just drop over the fixing points.
In operation the difference is remarkable. Night and day really. I fitted my Thule Proride 591 bike carrier at the same time as the bars but even with that fitted the wind noise, which previously was unbearable, now barely registered above the road and engine noise from my 1.7 CDTi Corsa. I have taken a few pics but haven’t been able to host them anywhere yet. In any case, there are pictures of the actual kit for the Corsa on the Whispbars web site.
Anyone want to buy a set of Thule aero bars for a Corsa D 3/5 door? Didn’t think so.
