Finally got my frankenstein-roof rack set up the way I want it.
-Allroad/A6 factory cross bars trimmed down on the ends
-Yakima raptor bike attachments trimmed so the trays can slide
-All the stupid yakima wingnuts replaced with actual nuts
My bmx, fixie, and 29er all fit with their wheels on. Hatch still opens, nothing in the way of the sun roof, still uses the oem audi locks on the cross bars. Even without a fairing this set up has way less wind noise than any rack I've had that had yakima bars and a fairing. It's super stable and looks pretty oem+
