F13 M6 weight distribution

[bleunetizen]

New to the F13 M6 and trying to gather some information.. My owners manual does not have that information.

Does anyone know the weight distribution of F13 M6? I googled and found F12's data but not for F13..

Thanks guys

A fellow kiwi, hello!

I have found the following:

52.83% and 1903kg with full tank, Carbon Ceramics and Akrapovic exhaust.

52.6% and 1928kg, not clear on options but would assume steel brakes

52.9% and 1895kg. Carbon brakes

52.5% and 1894kg. Carbon Brakes

wow hi there!

Thanks for the information

i remember seeing many 50:50 from m cars back in the days, i wonder if this is no longer the case or just the 6series, my old m6 also is slightly nose heavy!

50:50 is just a damn marketing claim which makes no sense at all. All the exotic/race cars are rearward weight distributed;
most of the front engine cars are are forward weight distributed unless those with transaxle configuration such as AMG GTS....

The smaller engine option in most BMWs makes them closer to 50/50 than bigger engines ones. I.E. in the 3 series the 4 cylinder is bang on and the 6 makes it front heavy.

Agreed with what M6-Coupe said though, most cars designed without compromise have a 53-56% rearward bias such as the Ferrari 612, FF, 599 and F12. The AMG-GT also and that does amazing lap times

yeah rear heavy is better for handling than front heavy unless biased to rear too much which makes no grip in the front.

some say slightly being nose heavy is good for handling because it becomes 50:50 under acceleration but im not so sure about that, chances are the weight will be shoved to the front before turn in because it always comes after braking. the turn in of cars greatly affected by weight distribution. being front heavy just hurts cornering performance and turn in sharpness, it can be corrected to certain degree with suspension setup though.

not necessarily saying 50:50 is better, just saying nose heavy is not very welcome.. haha

M6 CP is slightly heavier in the rear

may be i should always drive with full tank of gas and put some luggage in the trunk? hahah

still, F13 M6 corners so well for its weight, I am very surprise to be honest. perhaps its the tyres doing its magic than the suspension setup, but im pleased to know it handles so well in stock setup!

No this is not accurate measurement. Most likely a typo.
The actual measurement for M6 Coupe is 52.5/47.5

M6 Convertible has slightly heavier rear than coupe but still front is heavier than rear... 50.7/49.3

Competition package has nothing to do with weight. maybe couple pound because of steering and suspension.

Agreed, any difference would be amazingly small. The figures on that website btw are the ones uplifted from the USA website but it doesn't list on the USA website if they weighed a car with comp pack or not. Regardless it won't affect it too much at all.

The biggest differences will be CCBs or not and if the car has lightweight forged 343Ms or the heavier 433M or 601M wheels. There will be an even bigger difference if the driver has been eating too much

'Verts are much more rear biased and the GC is ~0.3% further rearward but also about 80-90kg heavier
