*I have a 435, but believe these wheels would work/look even better on a M4*
For sale is my forged Vorsteiner VFF-101 I've had for maybe 1 month.
Size 20x8.5, 20x10
Tires 245/35/20, 275/30/20 Nexen N3000 80%+ Even Tread Excellent Condition no repairs.
They are in basically the same condition as when I received them.
They have been shown to be one of the lightest monoblock forged wheels, even when compared to HRE etc..
Cosmetic 9.7/10 - VERY minor mounting marks etc, not noticeable at all
Physical , Working 10/10 - no Bends, no Cracks, no vibration to 100+
I'm not sure of the offsets, these are custom by Vorsteiner for the 4 series and were the wheels used for their photoshoot (white 4 series). I am dropped on KW V2 and am at .5 cm - 1 cm gap. With 4 people in the car the rear wheel tucks perfectly into the fender and I do not rub.
I prefer a local sale for 2800 OBO. I am willing to ship, at buyer's cost.
I may also consider a local trade for a 19" Quality Wheel (Forged preferred).
The car looks pretty sick with the wheels on.
