+1, I was going to post this. Definitely used the diffs to lifts the car with a floor jack. I would only use the pinch welds with the oem lift and only in an emergency.
Also helps to drive up on a couple blocks of woods as well prior to lifting the car - since the Impreza is so low, it makes getting the jack to the diffs a little challenging. Driving up on wood blocks helps a lot
