I am looking to upgrade my 2008 CTS from FE1 to FE2 suspension as well. I was thinking of just upgrading to stiffer shocks and not doing anything else (no new stabilizer bars or larger tires, etc). I just want a little more of a controlled ride - not looking for super sports car handling. Do you guys think just new suspension will be OK? Or do you have to get the larger/stiffer bars as well?
While we are on the topic - any recommendations of exactly what brand/model of shocks I should get?
