Guess: M3 / M4 Wheel Specs & Offset?
Anyone have a guess on the wheel specs for the M3/M4? Currently have a F30, going to be buying track-dedicated wheels. Would be awesome if I could get wheels that I could get to fit both cars with spacers.

I basically have the same question. I currently have an e92 M3 and will probably end up trading it at the end of next year for the new M4.
If I buy 18x10 wheels for my e92, does anyone know if they will fit on the new M4? Thanks |

19x9 and 19x10
We know they are 19 and the 20s on the concept are not seeing production. We also know that the wheels on the new car are forged so you may not need lighter wheels since you'll likely need bbs FI to be lighter. BTW please do that and post pics. |

Got it. So if I buy 18 inch wheels (for track) for my E92 M3, do you think they'll be too small for the M4? Should I consider buying 19 inch rims instead?

Excellent point. People hear forged and automatically assume that the wheels will be light.

Another question is about bolt size. The E9X M3 has 12x1.5 size while the F3X has 14x1.25. It is therefore likely that the F8X will also have the bigger 14mm bolts.
Would the bigger bolts fit wheels used on the E9X? I would like to know if I can keep my Enkei NT03 track wheels for my M4 EDIT: I just realized I have 14x1.25 bolts at home. I just need to see if they fit in my track wheels. Now the question regarding the offset still needs to be answered. |

The offset above is 30mm. 100+40=140mm wide wheel 140/2=70mm (wheel centerline) 70-40=30mm (offset of mounting flange from centerline) or: 100-40 = 60/2 = 30mm offset. However, it would be far easier to use a small "dentist type mirror" and look at the offset value that is stamped or cast into the backside of one of the spokes (it's the ET number). So, if someone could do that, then you would have the exact ET/offset value Offset is #2 in the above picture, but here shown as being stamped behind the hub cap cover.
