Hi @Rhubarb!

Thanks for reaching out again. You’ll notice, I have moved your question here so that it is easier for you to have the majority of the answers in one place. 

Here is what is specifically recommended by Yakima to fit your car. You will need the Yakima Ridgeline Towers and Ridge Clips. The clips are sold separately. You will notice the clip number for your specific vehicle is 36. This is not currently available through REI. I am sure Yakima would be happy to help you secure this inventory. As you mentioned, you’ll want the Yakima 55” HD Bars and Yakima also recommends getting the HD bar adapters to complete your setup. 

Unfortunately, the Showdown is not compatible with this setup. Here is a link to Yakima’s load assist racks and their compatible SUP carriers and kayak racks.

At REI, we believe time outside is fundamental to a life well lived.
