I was wondering the same thing, i reached out to Rago and they said it would only fit the R1t, when i asked if they had tried it on an r1s they said no. I gave them my info in case they decide to do any r1s development in the future or want to try to install it on a r1s. im just a few hours away...
Wind noise is definitely a concern, my goal is to get it mounted as far back as I can without interfering with the fin, and as low to the roof without touching. I'm surprised everyone likes black so much I thought the color match on the side rails looks unique. But black is easier and cheaper.
So long story short I had a 4runner with an uptop overland alpha roof rack. Love the rack design, took it off when I sold the 4runner and started exploring roof rack options when I get my r1s. I'm not crazy about anything on the market and feel most are way overpriced, so I had the idea to see...
