I am sad to say that I am putting my Vossen VVS-082 up for sale. I bought these thinking I would be able to do some type of mod to have them fit my 1st gen CTS. They fit but were too wide due to adapters. I didn't like the look so I took them off. They would fit perfect for the 2nd gen CTS. Here are the specs...
Size: 20x9 (front) and 20x10 (rear)
Bolt Pattern: 5x120 = 5x4.75
Tires: 245/30/20 (front) and 275/30/20 (rear)
The tires show wear and would need replacement soon. But this is a great deal because these sell for over $2500 for the wheels alone.
