SLP Bilstein suspension???

[Warbird]

I've been doing some searching. SLP is selling their Level II springs and Bilstein shocks under the Camaro SS/Firehawk restoration section. How does the Level II compare to the Level I suspension? I was thinking of getting the Level II parts since I want a firmer ride with good ride comfort, and a drop less then 1". Would the Level II be what I'm looking for? Also, since the drop would be less then an inch, would I need an adjustable panhard bar and an adjustable torque arm?

level II is the 1LE package, if I remember well.
I know they are Koni's instead of Bilstein for level I

The 1LE suspension consists of Koni adjustable shocks, stiffer springs that do not lower the car, harder durometer bushings, as well as several other differences compared to the SLP Bilstein level II suspension.
