bit off topic...but thanks Brian!
BMW F01 wheels C09 from Alpina
Specs:
8,5Jx21"with 255/30/R21 ET25, spacers 10mm
10Jx21" with 295/25/R21 ET41, spacers 30mm
The rims are not the best choice for the M6, you canīt mount bigger tires, but the look is great.
Tires are Continental Sport Contact SP 6 UHP, these are much better than the Michelin SSP, lot of more grip.
Cheers
Chris
