Lift points - where to place floorjack?

[Craig Detroit]

Where are the best points to place a floorjack for changing out tires on a 2002 GT?

I just ordered some new wheels and tires from tirerack and figured I would get a floorjack to make the swaps vs using the factory jack. Especially since I plan on putting winter tires on the current wheels and swapping back and forth twice a year.

In the front, I always lift it by the K-Member right infront of the oil pan.

In the back, I lift it from the center of the rear axle.
