We haven't tried an AirBar on a Minitubbed Nova yet, but I can't see why it's not possible. All the mounts are to the inside of the frame rail. The only problem I can forsee is the with the lower bar. I have see guys move that in as well, but you gotta know what you are doing.
Tony, I think he is referring to CPP's new Mini Subframe setup.
