Same for coupe and sedan?

What about the other specs?
Care to share where you were able to find that?

I keep reading conflicting information. Some sites say 5x120 like CTS-V and some say 5x115 like ATS.

I've also seen 67mm center bore and also 70.3mm center bore.
Thank you I appreciate the help.

Cadillac dealer is clueless. They are still checking with their "technical" people.

Trying to line up winter wheels/tires so they are ready when I take delivery of my car.

The dealer suggested that I take their winter wheel/tire package for $3500.
Tirerack hasn't measured the car yet so they have no recommendations.
Thank you. Tirerack updated their site.

I will look tonight.
