And what all does the performance pack option include?

All 08-10 models have the same appearance. Same bumper covers, grilles, rocker panels, spoilers, wheels, etc.

All SSs have the same 2.0 Turbo engine. It's rated at 260hp with a stick and 235hp with the auto. I think the only difference is the tune. correction: 235HP on first gear for the auto, 260HP for all other gears

On 08s, there's an optional Limited Slip Differential, but it was only available with the 5-Speed manual transmission.

On 09-10s, the Limited Slip Differential was part of a Performance Package which also included Brembo brakes. Again, only available with the 5-Speed manual transmission.

All 10s with the 5-Speed manual transmission had the performance package.

The RPO code for limited slip differential is: G85. Check the Service Parts Information Label and if it has G85 on it, the car has the Limited Slip Differential. On my 08, the Service Information Label is in the glove box.

Sun Roofs are common on the 08-09 SSs, but not standard. They were standard on 10s.

Pioneer Stereos are common on SSs, but not standard. The Pioneer Stereo includes a sub-woofer in the left rear trim panel. 09-10s have a USB port on the face of the radio for playing MP3s.

Remote start is standard with the automatic transmission, but is not available with the 5-Speed manual. Remote start was an option, here in Canada, for automatics.

All SSs have a leather/suede interior. I think the suede was black in all models, but the leather trim was available in three colors, black, white and red. In fact, the leather trim is grey, not white.

Front suspension noises seem to be common on these cars, but I don't think it has anything to do with the year model. They seem to mostly come from either the sway bar or steering column. Some people say it's a poor design. I haven't checked out the steering column yet, but the sway bar problems seem to be more a matter of GM using cheap parts than a poor design. Once the sway bar links are replaced with Moog links and the bushings are replaced with polygraphite ones, most people report the sway bar noises are gone.

Hope this helps!
