I have had lumbar support on a few cars and personally I do think its a worthwhile addition to any car, especially if you get out aching after a longish drive. This isn't a complete cure to the soft seat backs in the M-sport seats, as the seats wire frame is still pretty soft. However it helps to add another level of support to make the seat feel more firm in the lower back area and a worthwhile mod imo. I don't know if all 1 Series have the same seat backs or configuration for removal, so just in case this is for a 2010 E87 M sport seats.
My last car didn't have it so I bought this from Corbeau " onclick="window.open(this.href);return false; and pinched it back out of the car before i sold it.
All you need is 1 lumbar support.
Some trim removal tools and pliers.
Cable ties.
See pics below.
Corbeau Lumbar support
The seat back is held in with 2x3cm long plastic trim studs/pins at the base which are very secure. So i used trim tools and pliers.
Once you remove the Studs/pins the hard seat backs pull down and away. Again this requires a little force to pull away at the mid point, and then the seat back simply slides down to allow the upper retaining tabs to come free from the seat back. So away at the base, pull away in the middle with some force, then slide it down to clear the 2 large top tabs.
You can see the pipe work for the side bolsters which are operated via the seat switch.
On the right I unclipped a portion of the seat liner so I could neatly thread the lumbar bag into place behind the wire supportive frame. I loosely cable tied the support into place so it can move and expand..
Cable ties in place and finally clipped the liner back in place. The hard seat back fitting is reverse of what you did at the start. I didn't break the 3cm studs but they aren't exspensive from BMW i'm sure/hope...
Finished and lumbar support neatly in the gap by the driver. JD
