Jacking up a 1999 Toyota Solara with a Floor Jack

use the "sub-frame(s)" to lift the car and place the jack stands. In front, there is a sub frame member that is really solid going across in front of the oil and transmision pans. There is a small round protrusion in the center, and I lift with the hydraulic jack there, then place jack stands on either side. There is a tubular section that the jack stands can cradle securely. Next move the hydraulic jack to the rear. There is a similar sub frame member there with a round protrusion in the center. Place the hydraulic jack there.

12" length of 2x4 on each jack stand in back is helpful to spread the load at the jacking points on the side - otherwise you'll bend the sheet metal flange and break the spot welds.
