Anyone mounted an Autopower rollbar in a 996?

I mounted a 6 point cage from Autopower into a 350Z. It was a huge effort, just drilling all the holes for the sleeves - and then added it had to be welded in the floor inside the B-pillars, and in the rear top brace. Also the passenger seat could never really get back to a comfortalbe position unless the passenger was really short.

However, the cage was without doubt a serious piece of protection, incredibly rigid solid and I never regretted it. However, I won't ever do a 6-point again for a mixed street/track toy and especially not this type of destructive work to make it fit on a 996TT, it did take a lot of non-reversible work on the Z to get it in there.

Wanted to hear if anyone mounted a 4-point Autopower rollbar into their 996 and if that was any better overall than what I went through, like not having to weld the "bolt-in" cage in the floor, still being able to roll back the passenger seat a long way etc. Want to know since I still feel the Autopower has some serious quality to it when it comes to solidity and strength, just don't want to mess up the car as much.
