M5 vs M6 suspension differences?
While the M5 and M6 are overall the same platform/chassis, the M6 has significantly different wheel widths and offsets. I'm curious if this is the only change to the suspension/geometry or if there are other suspension differences that work in tandem with the different wheel geometry.

The hub face to hub face distance is the same on both and a lot of parts are the same if you flock through realoem.com and go through the various part codes.
There are different spring rates for the different cars - obviously the F12 is going to be stiffer in the rear due to the extra 200kg or so if the roof but other than that they are all the same. Not sure about alignment specs - one chassis type might be given values in a different range to another but that will just be different values, not different hardware. |

While I think the meatier look of the M6 wheels might be nice, I'm far more interested in a car that drives "right" than looks good. My understanding was already that M6 wheels bolt up correctly with tighter but sufficient space in the wheel wells, but I really don't want any adverse handling effects. |

A few people have run the M6 wheels on M5s and they look quite good. Note one thing, while the 10.5" width lets you run 305/30r20 in spec I think I remember reading that on an M5 they'll rub so you can only do 295s on an M5.

I've also read a few reviews where drivers found the M6 to be more engaging and lively than the M5. I'm wondering if any of that could possibly be attributed to the slightly wider track? |

I checked through now on realoem, what I found interesting is that all parts are shared between F10 and F06/12/13 such as the axle carriers, suspension arms, sway bars apart from the springs. As you know of course the Comp Packs have different shocks and sway bars to non Comp Pack cars, but all of those parts are shared for all Comp Pack cars apart from the front springs where there is a small difference, the non-Comp Pack F06/12/13 have a bespoke front spring for each chassis, but the Comp Pack M6s all share the same spring, F06/12/13 although the M5 Comp Pack is different again. For the rear all 4 chassis use different springs.

I noticed that too which was very interesting. And I wondered how much of that was due to the change in track width from wider wheels versus other differences in overall weight distribution throughout the vehicle.

Shame we didn't get a transaxle and have more weight at the rear - it'd make the M6 a whole bunch better
