Hi all. I'm following this thread with enormous interest as I'm possibly looking to replace (or maybe complement?) a '13 CTS-V with an AWD vehicle later this year, and wanted something more luxurious, but only if it could be modded for more power. I was very interested in the K900, but only if work of this sort could be done. Your dealer sounds like the place! Looking forward to the pics and hearing how it drives!Brent, thank you for all the kind words. It has been an absolute pleasure brainstorming with you on this project. The K9 looks amazing and is almost done. Pics to come..........
