NAV: ~12lbs
Fold Down Seats: ~38-40lbs
Ehanced Audio: ~20lbs
EDC: ~10lbs
DCT: ~58lbs
TOTAL 197lbs


Most of these are options on the F8X as well if I understand it correctly.
Not really reliable source, but it was mentioned in one of the other threads that US curb weight included the "Automatic" transmission option. And when I looked into the weights they add up...

US weight: 1681kg
EU weight: 1675kg (confirmed with DCT)

Difference between US and EU is 90% and 100% fuel. The M3 has a 63l fuel tank. 10% of 63l is 6,3l. Density of petrol is 737.22 kg/m3 and those 6,3l extra will weigh in at 4,64kg extra weight, getting us to 1679,64kg...

Also according to EPA regulations, options that are expected to be installed in more than 33% of the sold cars must be included in the curb weight. I'm pretty sure BMW expected the DCT to be sold in more than 33% of the M3's

a) (1) Where it is expected that more than 33 percent of a car line, within a test group, will be equipped with an item (whether that item is standard equipment or an option), the full estimated weight of that item must be included in the curb weight computation for each vehicle available with that item in that car line, within that test group.
