SLP Level II Suspension Package Question

The '96 SS I just bought rides like a brick compared to my '99 Z28, and I noticed inside the passenger door, an SLP sticker saying the car is equipped with the Bilstein Level II Suspension Package.........I ain't complaining about it, because it corners excellently :D , but does anyone know what the kit includes vs the Level I package?? (I have done a search, but no info).

The front springs are 300/450 progressive springs
the rear springs are 115/185 progresssive
Springs are charcoal colored

The front Bilstiens are revalved for 130 comp 397 rebound
the rear are 86/174

Sway bars are (1LE) 32mm front 19mm rear (21mm 1LE was not used) with 1le bushings

and 1LE Rear Lower control arms

Thanks for the info!

I'm suprised it seems to ride harsher to you. I've had three fourth gens, and the Firehawk with the Level II seems to ride the best of any of them to me. Plus it definitely handles a lot better.
