Feasibility of 4pt rollbar and racing seats for dual duty car

My post was confusing, here's a better explanation:
The seat mounting hardware is all BK, but in the case of the GTSs, the shoulder belts were attached to the oem GTS bars instead of the BK harness bar.

The GTS half cage is perfectly set and was able to be legally sold in the US, it was a main reason to buy them!

Thanks for the clarification. It just sounded odd that the GTS roll bar had been removed. I definitely agree with the factory roll bar being one of the main reasons why you’d purchase a GTS. It’s part of the complete package that makes the GTS superior to a Comp and base model.

Has anyone run Sparco QRTC carbon buckets https://www.sparcousa.com/product/qr...mance#readmore with the Schroth Quickfit pro? I am considering getting a bucket seat as the stock M seats are crap for lateral Gs.

I don’t Schroth makes a quick fit for the certified for the f80. I heard some hpde groups won’t let run them for that reason. Ymmv

For me I went with Cobra Nogaros with BK mounts on f30 manual sliders. Fit wasn’t great but I got it to work. BK was actually very responsive with suggestions. I have the BK harness bar in order to run a 6pt. Every dual duty setup makes compromises but I think this one is one of the better ones.

F80 seats can't work with the Schroth harness because the back of the seat is solid, and there is no way to run the belts through the seat.
