I have the Windstop. I don't have a roll cage.That being said, you will definitely need to modify the Windstop in order to use them together. Looking at the pictures of the Wolfe 4-pt cage, my guess is that these two products are essentially incompatible. It would take some serious hacking on the Windstop to make it work.
Of course, an ingenious person might come up with some sort of clever solution, but I don't see it.
