My '11 Coupe has 14mm wheel studs, earlier ones had 12.5 mm. Anyone know what year it changed ?

Just looked and for my '11 coupe, I have:
- Center Bore: 66.9 mm
– Wheel Fasteners: Lug nuts
– Thread Size: M14 x 1.5
- Bolt circle 5x120

5x115 is the earlier (Reatta, Allante) FWD

BTW BMW is also 5x120 14mm but the spokes hit the front caliper bracket.

Mine is 5x120.

In the .sig. My 2011 CTS Coupe is 5x120 14mm. Also have Allantes 5x115 12.mm. My little finger fits in a 14 mm but not a 12.
