Here we have a 2009 Audi S4 getting fitted with a Yakima base rack system. We start with two pair of Landing Pad 7′s. We then mount these directly to the sheet metal. We attach these close to the door frames adding extra hold. These kind of installs typically call for a 28″-31″ inch bar spread. By doing so, this allows you to hold Cargo Boxes, Skis and Snowboards, Bikes, and even kayaks. Before we attach the Landing Pad 7s we First insert a plus nut, allowing the Lp7 hardware to thread into your roof. We also apply silicon preventing water damage and rust.
Next we need a set of Yakima Control Towers. This is the tower that mounts onto the Landing Pad 7s, the Yakima 48″ cross bars also attach to this tower. The paticular step needs no hardware, just a few simple measuremets to determine the over hang outside of the towers. The Control tower has a quick release feature allowing the user to remove the rack within minutes. This then leaves the mounting hardware still attached to your roof in certain locations. To prevent theft of the rack we highly recommend Four Sks Lock Cores.
