just in case anyone cares. I think I might have found a potential solution to this.
Since the crooked seat angle applies to the driver side seat. I.e. In USA LHD driver seat is crooked, and in other parts of the world RHD driver seat is crooked, I am going to order the passenger side seat frame of a RHD vehicle to swap into my LHD driver seat. Per real oem, they are different part numbers which may solve for the crooked seat issue. If that doesn't work, I also manage to find a junk set of driver side seat rails. I am going to try to widen/elongate the holes at the rail to give more degrees of freedom to angle the seat dead center. Then I'll clamp down the seats with larger washers. stay tuned for pics!

riddle me this
Quote:
If the seat rails are positioned outward and pointing straight ahead (so the steering wheel offset from the seat does not cause many to lose sleep), will the side air bags will be less effective? More dangerous? Both? Disable the air bags? |

What i am aiming for is symmetry of seat position between driver and passenger seat. This was the intention of the f87’s designers as evident that the mounting points for the seat are straight ahead and symmetrical. until side impact rules made it so that they had to tweak the driver seat frame/railing a bit rather than reengineer the whole chassis. Had they tweaked the passenger side as well to make it symmetrical with driver, my OCD would have been less obnoxious |

"until side impact rules made it so that they had to tweak the driver seat frame/railing a bit rather than reengineer the whole chassis. "
So that sentence is the one that acknowledges there are safety considerations to what you're doing. I mean it's your car so if you're ok with that by all means I'm not going to tell you not to. It's just what the poster above was getting at. Airbags may be designed to work with a certain gap or whatever else, but if it was safety regs that forced the change then undoing it will have safety impacts. Anyhow, I'm still curious to see how this goes! |

For starters, the seat rails just does not have enough lateral material to widen the holes where the mounting bolts slide through. Otherwise, this method would give more degrees of freedom. The RHD (passenger electric seat frame) is identical to the LHD driver seat frame (despite slightly differ part numbers) LHD Electric Seat Frame P/N: 52107285859 (driver) 52107285862 (Co-driver/Passenger) RHD Electric Seat Frame P/Ns: 52107285860 (Driver) 52107285861 (Co-Driver/Passenger) it is really the mounting points on the floor pan that makes the seat tweaked. The only way I see this being fixed is if the carpet is removed, break and reweld the seat mounting braces (1, 2, 3, and 4) here: https://www.realoem.com/bmw/enUS/sho...diagId=41_2159 In other words, not worth messing up to get it straight. just have to live with it. |
