Does anyone know if the Thule 810xt sup taxi fits the OEM base rack on a 2011 Cooper S hardtop? When I emailed Thule, They said that none of their systems will work with my OEM base but I'm seeing that others are successful with other Thule types while searching for an answer. If so, any mods to get it to fit? I have 2 sups to transport and looking for something that will lock against theft and is quality.

If not, does anyone have a solution that is working for them? Thanks
