Screwed up alignment

I got a question. My alignment is off, I took my 96SL to a firestone to get it fixed, because my 2 front tires were wearing out on the outside edges. I bought the tires this Jan. They tried to fix it, but said all the adjustments they could make were maxed out. So they aligned it some, but the left front camber is still way off specs. So 2 mos. later the rear tires which were put in front are beginning to bald on the edges. I need to get this fixed. Are there some aftermarket control arms or whatever, that have more range in adjustment, that I can buy to take care of this?

If you cant align your front end and you arent lowered there is a good change you have bent something up front.

Can you still align your car even if it's lowered? You should, right?

Yes you can, but you sometimes will need aftermarket parts to do so.

So, could I get those adjustable camber arms from 3sx for the rear and install them in the front to correct the problem? The firestone also said something might be bent. But going to a body shop and getting it checked out and corrected will probably cost me an arm and leg.
