That's freaking awesome! I don't think I've ever seen that in a seat before.

I doubt they fit, they seem too wide to fit in my car but I haven't tried
Yeah those seats look really nice. I like the headrests too. Can't stand the headrests they're putting in cars these days that push your head forward like your some sort of paraplegic.
headrests are power as well
looking for a DIY guide for lumbar + side bolster retrofit on M3 seats... any suggestions? The ones I keep finding have expired pictures.

first my kit wont work with your seats because you also need the seat foam. apparently the seat foam is different than non bolster seats. it has its own PN.
but here are a few DIY links for you to chew on.
this is not a complicated retrofit especially if you are technically inclined meaning you pay attention to how things are when you pull tem apart as opposed to some people that just take things apart and dont pay attention. there is no coding involved, no crazy wiring. no running wires into fuse box ect..all plug and play.
i followed this doc for lumbar retrofit into sport seats... its literally the same for M3 seats.

this link is for someone whom did the retrofit and gave points hints and thoughts but no pics since he said it is cut and dry.

i sent you plenty of pictures of how the items looked so you should have a good idea of how they fit onto the seat frames but here is a pic of a bare seat frame with the bolster system in place.
i believe it is very self explanatory in how things fit in regards to the bags and lumbar. your seats wont have any of it so the system just fits int your seat frame since there are spots to accept the parts.
i take pictures of things before I remove them so i know how they go back together.
the last picture shows the wire harness from the bolster pumps.. it just comes through and lines in with the seat switch main cover and it has a single 2 pin plug that plugs into an existing plug hole in your seat switch. no splicing, cutting, routing to fuse box etc...
