I feel like they hold me in just as well as the LWBs and fit me the best. I would say I found the 18 way to be the least comfortable.
I love mine in the 997.2 GT3, lowest level Porsche is still great!

997 GT2 (3) C/F bucket seats were the best IMHO. Used them in 3 cars, GT3, Carrera S and GTS. And they reclined!! Didn't find the new 991 buckets in my 16 RS any where near as comfortable. Ordered 4 ways for my 19 GT3. Will mount a Sparco SPX seat for my daily and track day use and let the wife keep the passenger 4 ways. She refused to ride in the RS because of the fixed seats and I found that they aggravated my back. Its a shame, they are great looking seats, just not comfortable for me.

If you need a extra mint set of SPX seats (only 500 miles), let me know. They are up on the marketplace.

Interesting comments by Patrick Long on "The Smoking Tire" podcast. Patrick whom of course has experience with long drives in 911's, discussed the custom seat inserts racers use. He says lower back discomfort stems from lack of hip and thigh support. If hips are sliding around, lower back gets cramped from trying to stabilize things, not so much from lumbar support. It seems to make some sense.
I personally have been happy to find the LWB's comfortable, despite some lower back pain history. Getting out a bit of a challenge.

See this thread for pictures and discussion of foam and other solutions.

Also, a solution that I used; A simple adjustable bladder that fits behind the cushion and provides tunable lumbar support.

I have lower back issues and the LWB in my previous 997.2 RS and current
991.1 GT3 are the best seats ever. Complete support. Most seats with lumbar support do not work for me and the inflation only makes matters worse. Only other seat that comes close is the seats in my VW GTI made by Recaro. Now getting out of the LWBs at near 70 is another matter.

However as a physician specializing in the spine,
I would strongly recommend against GT cars with LWB for 90% of patients who have had lumbar fusions and 50% of patients who have had other less invasive spine surgery.

For a respected high end car maker Porsche seem to get some of the simplest things wrong when designing cars.
I completely agree. It still blows my mind that Porsche can't offer a more adjustable seat, better padded racing seat option. Ferrari's adjustable backrest, in addition to more padding, really makes their CF seats extremely supporting in addition to being quite comfortable.

I have swapped Challenge Stradale seats into one of my cars, and Enzo seats into the other. Both have an incredible amount of padding, as well as adjustable backrest angle. They also make you feel hard wired into the car. Having a good seat makes or breaks a car, in my opinion. Makes all the difference in the world.

Been saying this for a long time. My back issues pop up when a seat is not holding me well enough and I'm constantly having to use my core muscles to stabilize myself against the cornering forces. It's not the lumbar, it's the lack of lateral support. Since my back issues are so bad, it doesn't take much to bring the pain. LWBS are a godsend for me. Zero pain even after hours in the seat. I'd never buy a Porsche again without them.

Just installed the Tracspec seat recliner brackets and I'm hoping this change alone will prevent any back issues with the LWBS's. I am now tempted to get a bit of memory foam, considering how cheap an add this is. It is what we also do with our Recaro race seats.

I couldnít agree more. The race seats are indeed upright but after settling into them, I can go for hours. It surprised me at first but they really work for me.
