Ah, I think you missed the fact that Johnny is using custom steering arm plates which resemble the geometry of the arms on the original X20 steering hubs. It looks like the steering linkage mounts a little further back on the arm compared to the stock plate. As a result, he likely doesn’t experience the same interference you do. I didn’t notice it at first. I think I finally caught it after the third read through, lol.

One thing you might want to try (not sure it will work) would be to flip the swing arms on the floating mount so that the arms hang lower, then flip and mount the rack on top of the arms. This might alter the height of the rack just enough to clear the arms, but I don’t know how it might affect the steering geometry.

I guess my only frustration with this car lies around the option parts. While it’s great that Serpent really thought about all these tuning options, they lack the details of how and when you use them in some instances. For example, when I bought the floating mount for the original X20, I had no idea that you had to buy a different set of mounts for the swing arms to mount to it. Not that I’ve actually needed it, as I haven’t had an opportunity to run on carpet - but I love the way the car handles though!
