We were trying to install my stainless lines last night, but the floor jack is too high for my car and wouldn't clear the sideskirt, so we tried jacking the car up from the front. But my friend ended up bending some black brace under the engine area. It seemed solid at first. So where is the actual jacking point for the front?! Thanks.

The front crossmember. Locate it by looking for the small plate with four bolts underneath the car, that runs from front to rear. It's well behind the engine oil pan, not close to the front of the car at all. Place the jack point closer to the center of the rear two bolts of that plate, which is bolted to the crossmember. Sorry, I don't have a way to post a pic of the diagram or the crossmember.
I got this information from the Subaru service manual, Section 1, page NT-4. This is the jack point I use when I change my engine oil, which I just did today.
Do you think by denting that black brace under the engine I did any real harm to the car? I thought it was steel at first, but now it obviously is aluminum. It's just under the radiator and runs left to right.

I think you might have dented the large u-shaped brace that connects the two frame rails. If you didn't have to remove the plastic splash shield to put the jack under it, then it was something else. I'd have to take another look under my car to be sure.
Originally posted by ImprezaRSDriver Just make sure he did not jack up the car with the oil pan. I have seen people do it and it is not funny when there is a hole in it.
I hope not. By PimpWagon's description, I don't think this was the case. If I ever noticeably crushed my oil pan, I'd probably replace it and check to see if I damaged the oil pump pickup or anything else that occupies the crankcase.
The cross member sits behind the oil pan, so that probably wasn't it, since you would have had to really slide the jack in a long way. Sounds like you got the big U shaped sub-frame, which is not aluminum, but steel, which sucks. It is possible that you did tweak the front a little bit, since the sub-frame is there to support and stiffen the front uni-body.
I would say in the future get the car up high enough for your floor jack, by first using your scissor jack in the trunk. You can then jack the front up using the floor jack at the ribbed section of the body immediately behind where the sub-frame ends.
that last picture is confusing
is it the front or the back
i do a lot of my work myself...and recently...i will either jack up my car on the rear diff for the rear.
or....in the rear of the car....like a feet forward from the rear wheels, there is a bar that connects to the sideskirt.
i usually do jack it there.....am i wrong in doing so?
for the front...there is another cross membrane similar to the back...i will jack it on there also if im only doing one side.
the location of the front jack point i use is also a feet back from the front wheel....
I think I dented the same piece on my OBS. It left a circle shaped impression in the metal, which indicates that the metal is VERY weak. So, I believe this piece of metal in question has nothing to do with structural support. I think it's just a flimsy guard for the AC and condenser fans or something... no harm done, imo.
