After some deliberation I pulled the trigger and had Mazworx weld in a 4 point roll bar.
I bought the BRZ to be used as a track car mainly. I want to be able to use my HANS as I hope to run the car quite frequently. I checked into the bolt-in roll bar and harness bar options but I just kept coming back to welding a bar in. Worked with Mazworx on many other projects and they exceeded my expectations.
Just got done fitting the interior back in last night and have it all prepped for run Daytona with NASA this weekend. Will need to pull the interior back out and have the roll bar painted after this weekend.
We just had to notch the rear side plastics and cut the rear truck fabric to wrap around the cross bar. The only interior pieces that couldn't go back in are the rear seat backs (the seat bottoms fit just fine)
All in all it came out great...still can bolt in the stock seat and use the stock seat belt but being able to run my race seat with harness and HANS will be very nice.
