Edit, I was going to post a link to that same service manual page, but I was slow on the draw
It appears 8 “obvious” jack points are the correct ones.
- The four pinch welds on the sills
- The front subframe bolts and center point
- The rear torsion beam.

The rear torsion beam is the easy one. The front central point is basically inaccessible on the ST with the car on the ground.
I find the most efficient way to jack the car up is to drive the front wheels onto some flat 1” thick boards (I have some leftover bamboo, but a 1x8 piece of wood could do the same). That gives just enough extra clearance to slide the jack in next to the wheel and reach the subframe bolts. I just have to remember to slide the wood back under the front tires before lowering the car or the jack literally gets stuck under the car, but it works well and saves time, freeing up the pinch welds for placing jackstands.
