Sorry for this great delay! I did have a Cobra halo seat at one time, but I never installed it in the car because my shoulders were too wide to comfortably fit in the seat. My only seat experience in the Boxster has been the Recaro Profi XL, and the regular Profi, both which fit great in the car, both on OEM sliders and on the Brey-Krause floor mounts.

Hi Steve,
I found an old post about the Cobra Evolution Seat used in your 986 Boxster. I have a Boxster I am currently trying to set up for HPDE and am wondering if you mind me asking a few questions. First, I am very interested in knowing if the seat fit with a full interior. I am taking my autocross car and converting it, so I would like to maintain some minor "street-ability" with the car. ie, drive to and from the track, or run to the store in town. can you comment on visibility with the cobra evolution seat? i am not too concerned as the car is mostly a toy now, but i am curious. also, can you tell me if you ran a harness bar or just used the factory roll hoop. i am not very tall and am concerned about belt angles, but i have been searching and noticed that most people use the factory roll hoop for HPDE cars, and of course proper cages and harness bars for a Spec Boxster?
Thanks in advance and i look forward to your response.
