BOOM!There is a lot of bad info out there on wheel specs for the Quadrifoglio.
Here are the correct offsets (cast into the back of the wheel and verified with a ruler). The offsets are the same for the 5-hole and Tecnico wheel designs.
Front: ET 34
Rear: ET 41
The center bore for the Giulia is indeed 65.1Center bore for the 2017 Giulia's should be listed as 65.1 according to this site...
Anyone know what the actual Center Bore is (some sites show 63.4)?
Also if you find actual Alfa Romeo info please post up!
