Try a search next time. This has been discused a million times. The SS has 17" wheels and better suspension as well as the hood and spoiler. Some SS cars have a Blackwing lid and SlP exhaust from the factory.

The base ss has different exhaust and suspension calibrations even before the slp options I believe. I know in 98 they had a 3 inch exhaust on one side only. The additional slp items that are on the sticker are above the ss options added when the car went to slp.
