In the unlikely event you roll over and the roof caves, your spine is the one absorbing the hit. On seats that have a recliner, the recline mechanism can give way and not allow you to become moosh.

I've also heard the top of the seat shouldn't be higher than your head. I think Porsche may put fixed backs in their 911 as an option but I'm not sure. Other exotics to do it, don't they also need to meet US safety standards?
Fixed back seats aren't the concern, it's harnesses without a roll bar. The OEM 3point belt allows you to fold out of the way.

Fixed back seats are hard to execute with the 3 point belts. You have to make sure the lap belt passes through the bottom holes and hardware doesn't bind on the seat.

OP has a E90 which makes more sense for non-reclining.

I've got a set go Porsche/Recaro 996 GT3 seats in leather collecting dust; looking to get $2K out of them if you don't mind the Porsche crest in the seat backs

They are an excellent DD/track seat...

For tracking, get fixed or stay stock. Reclinables simply wont make enough difference to be worth it.
