I ended up reclining my seat a bit more and pulling the steering wheel towards me. The only thing really that can't be adjusted is the shifter placement, but it still feels fine.
I ended up going back and getting the Shoei RJ Platinum and it fits fine in the car. Granted, there's maybe a millimeter of clearance between my head and the roof, but it fits and I can move around comfortably.

Looking forward to race day.
