LWB and back issues
 
I had a chance to spend 90 mins in a GT3 with LWB last year at the Porsche Experience Center in LA. While I did spend a decent amount of time in the car I am still a bit concerned about LWB as they pertain to my lumbar fusion. To be comfortable for any significant period of time I need a fair amount of lumbar support. I hope to shop for a 991.2 GT3 in the next year or so and would prefer LWB for the track but I was wondering if anyone with back issues has any insights to their comfort for say a 4 hour drive.

I have 4 lumbar and 3 cervical fusions. No issues with LWBs. Cincinnati to Atlanta only stopping for gas.

glad to hear you tolerate LWBs despite your fusion.

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.

Comfort is subjective however if you plan to daily/ do frequent 4h drives, I'd opt for 4/18w seats and buy a dedicated track seat for those days.

On my first day of ownership I drove from Florida to Kentucky with the LWB.
I found that the lumbar support was lacking. I bought a piece of memory foam stuffed it into the lumbar area behind the seat cushion and now it's as if the seat was custom-made for me.

Memory foam is a life....BACK-saver when you have the LWB’s.

You can always track in an 18 or 4 way seat and be comfortable with daily driving if you use the car for both street and track...

LWB look the part but the others hold you in just fine.

I bought this one and it works well in the LWBS

I have LWBs on my 991.2 GT3 and 981 Spyder and have never had issues with my back despite being 52.I also have the Carbon buckets on my 458 and i find them more comfortable than the LWBs.I attribute this for two reasons.,The main reason is the 458 rides much better than either of my Porsches due to more supple suspension.The other reason is that Ferrari saw sense in having a knob to alter the backrest angle which is what Porsche should have done with their LWBs.
For a respected high end car maker Porsche seem to get some of the simplest things wrong when designing cars.

with that much hardware and your history, I'd also recommend sticking to the most comfortable 18-way seats you can find :)

I am a full above knee left leg amputee.....got hit riding a motorcycle.... I also have a degenerative disc in my lower back that give me issues...part hereditary and part from the way I walk with the prosthetic leg. Besides all that I am 6'5" tall so fitting in tight seats and sports cars is not really what my body is made for...LOL

I fit fine and can drive for 2-3 hours in my LWBS.

Where did you get the memory foam? I assume you cut a small piece of it to fit behind the cushion?

I drove 10 hours home in my LWBs on Saturday with my new touring. The seats are by far my least favorite part of the car. I’m a 100% healthy guy with zero back issues or pain, and within an hour, my upper back was aching. My problem is my upper torso and shoulders. I’m too wide for the seats there, which I was concerned about all along since I have a 48 inch chest. The buckets fold my shoulders in and hunch my upper back over. I don’t actually touch the back of the seat in that region unless I press myself into the bucket. I wadded up my jacket and stuck it in the right place and then was decently comfortable for the remaining 600 miles home. I have now owned every flavor of seat offered in the 991 and the manual 4 way sport seats in my 991.1 GT3 are by far my favorite. Kicking myself for not doing those in the touring. Oh well, the price we pay for style ;)

Take the center section out of the back of your seat and peel the velcro backing away and have an upholster add foam to beef up your lumbar support. Super easy to do and it really improves the comfort of the seat without changing the looks.
