I will try this week, another option I have in the meantime is my Reverie CF seat out of my Exige that I believe will bolt right up. I still like the idea of a full cage, although I understand It may create a problem for the aero. Comparing our height and inseam, it ends up that my torso is 3" taller than yours, creates a big problem for me in sports cars. With my Exige S, I had to go with the "down low" seat rails and the CF seat in order to get in the car with a helmet on.
Thanks, I will call Russ
