Thanks for the info. I originally had bought a Start 2007 seat for this car but the new design of the Momo seat was physically larger and I couldn't fit it inside the car. The older design is nearly 1.5" narrower overall. I just wanted to make sure it was still viable given it's age and bottom mount design.

My goal is to get lower in the car. Currently my helmeted head bounces off the roll bar and I just don't think that's wise/safe.

What are you opinions on the Ultrasheild Road Race halo seats? While I believe it can be mounted in such a way to get away from the bar over the window, how safe are they? Aluminum looks mighty flexy even with c-channel supports wrapped around the seat.
