you can do that but driving a car on the street with OEM 3pt belt and rollbar is not recommended. I know it's a tough pill to swallow. For safety, you almost have to go one way or the other.

I do have the ability to attach the OEM 3point with my bar and I still have the bulkhead installed for the receptacle but I won't use it ever. Won't even install it actually.

 

I'm 5'9" and have short legs so I sit close, with a lowered rail will the chance of the seat flexing enough to cause contact with the bar be that great? Because if so then I have to rule out the S2k completely then. I can't go to Mosport without rollover protection and I can't afford to have the car as a track only machine. If I had a removable harness bar would that make it any more safe or is it the main hoop that is the concern?
