I read the past posts on what type of jacks were used and the best way of getting our cars off the ground. I have full subframe connectors from Competition Engineering. The large jack in the back panel always worried me if I were to have a flat. I live in Australia and the new Ford came our with an equipped small sizzor jack that works great with the sfcs. I got rid of the entire original jack system and replaced it with this small one that does the job great. It fits compactly in with the spare and has its own little foam nest. Works for me. If the small one isnt available, a larger sizzor one will also work. Hope it helps some of you.
