When I had my old wheels and I lowered the car, it was rubbing on the inside. 17x8 +43 on 225/45/17 or something like that. You'll want the LCAs to undo the camber, since your specs are about the same. Besides, you wouldn't want to sink even more of your sunk wheels at the moment.
Like kpSTi, I did it the hard way, and had to pay for an alignment each and every time. Not to mention the headaches of taking the same bolts off 3-4 times (these bolts are a pain)
