I have a 2005 V6 with stock suspension and I am looking to put on ONLY the rear roush springs before I put on my new 18in Razors. I was wondering what else I need to install to lower this car properly. I have heard that LCAs and an adj panhard bar are adviseable. Also since I have a V6, I have heard that I will need to get a rear sway bar. Also heard that the rear roush springs will wear out the stock shocks so shocks would be advisable? What about bushings. Any opinions/other suggestions for what I should do? I have heard from individual people on this subject but was just looking to hear others. Along with any suggestions, a place to buy it would be nice.
