I don't jack the car by the subframe unless SFC's are welded. I've seen mustangs bend when jacking like this.
Instead, i jack by the pumpkin and put the stands under the subframe or on te axle tubes together.
Up front, i lift in the center of the k-member and put the stands on the outside edges of the k-member or under the ball joints on the a arms if i want it loaded.
