I have the Eibach Springs pro-kit. Once the springs settled. My LS dropped 1.75 inches. Pretty happy with them. Speed bumps are not my friend. I am real careful parking near parking blocks and curbs. I use to drag my exhaust tips backing out of my driveway. New exhaust and tips solved that problem.
Yep. I pretty much avoid speed bumps at all costs. If my gf takes the car to a gas station, I demand that she park at the pump because I know she would hit the curb otherwise.
