Seat options/ideas for street/track use

[NickD]

I currently have the comfort seats in my 135i which I just picked up a few months ago. Obviously the lateral support is quite lacking. I plan on attending a number of track days each season with the car but also use it for semi-daily street driving and need to swap the seats. I was looking at tossing in a set of e92 M3 seats, which I figure would be a nice balance between street and track use. I was debating if the M3 (or even e82 sport seats) woudl be a good idea (i do love the heated seats in the winter) or if I should go for a more track oriented seat (which might be a bit difficult for my semi-daily driving) and I do have a single, frequent, adorable rear seat passenger.

I'm just going to reply to my own thread. I picked up a set of used e92 M3 seats and they're fantastic! They should work perfectly. Just have the SRS codes to clear.

I did something similar - installed sport seats from a 2006 335i into a 2011 328i xDrive. Some of the wiring was a bit different (despite being closely related models), and it took some rewiring in the seat to make it work. The bolsters and the lumbar didn't work until I did that. Also the 2006 had no pyros in the headrest and would throw an SRS code until I moved the '11 headrests into the '06 seats.

So just a heads up it might not be exactly plug and play, but there will be a work around available.

Thanks, I have the passenger seat in and everything plugged right in and seems to work. It's been so darn cold out I haven't had time to really mess with it yet. There was a second 2 pin white connector, opposite the black connector that I believe is for the seat belt tensioner, which I left disconnected as there is no plug on my car's harness for it. So I'm not sure what that's supposed to do but I also haven't researched it at all.

Other options that help. Twist the lap belt portion. If in electric seats slide the back a bit. Latch belt, pull tight, slide seat forward. Your ass and hips should be well anchored it the seat. In addition if you stop by your local hardware store and pick
up some rubber tool box liner. In leather seats you sit on that and your ass is not going anywhere.

I've actually used that method in the past in an old 328i that worked well. I'll probably do it again.
