OP: You car has electric seats I assume? I seem to remember a member from Sweden saying that they could order the F8x with manual seats. If correct, that takes out a big chunk of weight. |

Does anyone know definitively how much weight is added with the steel roof/moonroof option?
Great thread, thanks for providing this info. |

Power seats is better than "electric seats" I guess... We just call them electric seats over here (in my native language). Sometimes direct translation comes out a bit strange...

It's not the translation, it's the translator.

The fact the car weighs less than its predecessor at all is good news. BMW is heading in the right direction. My hunch is the next generation will weigh even less than the F80. All this is good for handling, gas mileage, etc. Not so good when you have a collision with the soccer mom in the Suburban though.

Definitely don't quote that figure, lol. It's in the region of 50lbs.

When it comes to damping and moving the wheels up and down, the total mass of the wheel/tire/brakes will become relevant as unsprung weight. As far as weight, 19's with CCBs ~= 18's, so it would be a wash there.

Braking is a different situation as you can generate a significant deceleration rate and hold it all the way to zero mph. Radius of gyration is the value you're looking for to compare the 18 to 19 combo once you know their mass.

Personally I'm wrestling with the weight savings vs. the ability to add a roof rack/cargo convenience. If you want to add a roof rack you need to skip the CF roof. |

Ok, so maybe possible for stripper M4 to be under 3400 mark. I hope to have time next week to weigh my M4, but it's lightly optioned w/ HK and 19s so maybe around the same weight as Joes.

For example, on the E92 M3, the optional 19" 220M wheel/tire combo was lighter than the 18" base wheel/tire combo. My point is that without having the specific weight of the individual wheels and tires in 18" and 19" sizes, it is not possible to draw a conclusion on which option is lighter or has less rotational inertia.

The CCB reduce the effective mass (actual mass + inertial effects) of the car by about 20lbs. |

Now that we've gotten the weight of a stripper M3 pinned down, we must now start a debate over which wheels are faster! I propose that two identically equipped M3s save the wheel options do a drag race. I hypothesize that the 18" wheeled M3 will be .01% faster from 40-90 MPH! I think the reason I'd consider the 18's are more for using the $1200 elsewhere in optioning the car, cheaper tires down the road, I think the 18's look good (although the 19's look GREAT), less risk of wheel damage and perhaps a slight comfort advantage. I don't think the performance/weight advantage plays into it. My car will have the sunroof anyways, so I'm already adding 50 lbs.
