What do you want them to do?
How do you want the car to sit?
Mopars SS springs as thay come, 002 and 003 will sit higher on one side, unless you get two of the same pn, from what I've heard.I have not heard too many glowing reviews on the Mopar springs. Run a search for past threads.
I have seen mixed opinions on Caltracs on the street but no personal experience.
I went with Espo 1" over stock.
225-70R14 front and 275-60R15 rear. I think I would have liked 2" over stock better for the look,but no complaints about how they ride.
You're gonna get a lot of different answers, but you have to answer the two questions above first.
Good luck!
