I found the CA Vehicle Code online and it says: (http://dmv.ca.gov/pubs/vctop/d01/vc660.htm) The "unladen weight" of a vehicle is the weight equipped and ready for operation on the road including the body, fenders, oil in motor, radiator full of water, with five gallons of gasoline or equivalent weight of other motor fuel... So, you would actually need to subtract 5gals of gas weight (bmwusa.com says M3 tank+reserve = 20gals) to get the official "curb weight" (US). 3497.5lbm - 5gals*6.073lbm/gal = 3461.1lbm |

18kg for just a single external door panel seems a bit high, but I guess that's what it is then.

Glad it is useful. I purchased my first major mod after staring at the initial post: Vorsteiner exhaust. Couldn't resist is at $92/lb. It will be interesting to see if they come up with titanimum pipes.

I think it's a sedan, right lucid? Probably he has the sun roof since he said all options.
Seems the sedan is heavier. I'd like to see that compared to a completely bare sedan, no ZTP (no EDC, no iDrive), no premium sound, no premium, no PDC, etc. I gotta believe all the options add up. Still, its heavier than a loaded coupe though. |

Does the E90 M3 come with non-folding seats? If so, what's behind the seats? I remember us having a discussion on this earlier--that the chassis might be reinforced behind the seats on cars with non-folding seats for the E46 3-series I think. If so, that might also heavier, but I don't know the options on the E90 M3. Anyway, vague memories...

OEM seats and coilovers
Do the original M3 seats contain airbags?
There are racing shells like the Recaro Profi SPA which weigh only 8.8 pounds each but I don't know if that will delete the side airbags. If it's just a sensor that's in the seat that could probably be transplanted. Also, I was wondering if anyone looked into weight savings from coilovers like these: http://www.kw-suspension.com/en/30_P...port/index.php That would save on the original springs which are usully heavy. Very informative post. Thanks |

We have a Occupancy module that will be released soon for those running race seats and remove the errors.

I'll have to dig up our notes as well during the swap.
