Tony: you have to buy the 18-ways, and the wiring, and possibly the module that controls the seat if the PIWIS cannot program the installed module for the 18-ways. In the .1 they were different modules, I don’t know about the .2. Then you install the new parts. This was discovered by actually putting 18-ways into a car specced with 4-ways and then plugging in to PIWIS in 2016.

The system is designed such that you can easily plug the 4-way seats into a car that came with 18-ways, but if you tried to go the other way only 12 of the 18-way controls would work until you changed the wiring and modules. The jury was out on how much would work in a car that had come with buckets if you installed the 18-ways, but the wiring would definitely need to be replaced the last time I checked, again in 2016.

I do do not believe things have improved in the .2 since my attempt to spec a car with two sets of seats at build was rejected specifically due to the issue of module and wiring conflict. I don’t doubt there are other reasons.

how large was the dealer bill...?

Wow. That’s great. I asked 3 or 4 dealers and they said it couldn’t be done. Where did you get it done?

Where did you source them? I have been completely rebuffed by PAg when asking for the next car to be provided with both sets of seats. My search for 18-ways in 2016 only led me to the dealer and the price was beyond silly. I’d be very interested to have a set of sofas for possible touring use at a reasonable price even if I need to have the contrasting stitching matched.

Looking for 4 way (unicorn tears) or folding buckets (purple PTS unicorn tears) for a GT3T. Would settle for passenger side only.

exactly what I want

passengdr 4 way

ill bet suncoast can

I have 18 way in my GT3 with red stitching and none of you can have them. They are not leaving my butt

let me know if you sell your seats
