The rear upgrade I favor with the CTS is a QC, that will have to be my first step, and they take up a lot of space. I have three cars that are in the running when I make my final decision, a wide body 62 Lancer, a 72 dart, or a 72 E body, E is currently the most likely, depending how satisfied I am with the QC install.

The C6 install is not ground breaking enough for me. eyes laugh2

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
