It is nice to have the extra room for a helmet. But if you are someone who would use a sunroof, you will miss it. I love mine and use it often. I rarely put on the AC.
I also heard the Recaros can seat you lower than the standard Camaro Seats, so the sunroof would be less of a problem if true.
If it were me, and I planned on keeping the car, I would reorder.
