Iím 6í4 and have the sun roof. Ordering with or without the sun roof had me in a quandary for a while. Then I sat in one with the sun roof and said the hell with it. I wear a cap most of the time and have no problems. The one thing that I did not consider and wished I had was a helmet! I have not taken the car to a track yet but know I will have to wear a helmet when I do. The helmet is going to cause a problem. :( But I do love the sun roof!
Just an FYI
Searching for traction!
