Howdy! I wanted to share my thoughts on a recently completed half cage install project for my '18 M2. The cage, seats and harnesses were installed last week by Mitch Piper of Piper Motorsports in Leesburg, Virginia with parts supplied by OG Racing. I was very happy with the build quality and the overall service that Mitch provided for this project.
I just pulled together a short video on this project, which you can find on youtube here:
