I have GA bars on my Alero.
Don't get the metalic pads. I got them and they dust up my wheels so bad. I regret getting them. Plus the pads I got were defective the one side wore out in 7 months, the other side is new
For brakes, I suggest Summit Racing brand slotted and cross-drilled rotors and "PowerStop Evelotion" cermic pads. Work really well. The box for the pads is black with purple writing, because I know I killed that word.
KYB for struts. Eibach makes a good spring, but others have intrax. It's a lower drop.
For the sway bars, do the front only or do the front and rear. DO NOT ONLY DO THE REAR. Get the tower braces too. Help with body twist and the rear saved my car in the accident 3 years ago. If I didn't have that, the car would have been totalled
