Does anyone know the measurements (bolt pattern offset) for 18" and19" after
market wheels?

The factory wheels are 5x115 bolt pattern. Offset is 42mm.

The factory wheels are 5x115 bolt pattern. Offset is 42mm.

I am looking for aftermarket wheels too. I ordered an ATS with 17-inch wheels and I understand that they are 5 x 120, but I do not know offset. I obtained the info from www.hubcaphaven.com/cadillac/ATS factory wheels, Cadillac part 9598563. Niche wheels are being offered through D3 elsewhere in these forums. You could check with them. If you find a cool aftermarket wheel, show us some pix!
