Below are a couple of pics of my very basic rack setup.
I've had mixed results with this setup. In the second pic you'll notice the cracking around the top of the A-pillar that has been mentioned. Not sure if this was caused exclusively by the racks as the other side did the same thing shortly after I bought the car in Sep 2011 before anything was attached to the roof. That one was fixed under warranty, the crack in the pic was denied by LR because of the non genuine racks... Whatever...
The basket (home made) and tent are only on there for trips away.
Anyway, I think the best way forward for my setup will be to have rails welded between all the 8 feet to spread the load.
Nothing has rattled loose or moved over all my road trips which have included some bone rattling corrugations.
The only fault was the gutter above the passenger front door deformed downward slightly after a particularly heavy fore/aft pitching incident on Fraser Is. That has since been straightened with success.
As for the body flexing thing at full articulation, I have definitely experienced it. Maybe strengthening the rack might not be the best idea?? What can you do though...
