Lowering the car will send the camber further negative. As to iff it will throw it off far enough to canuse a problem is hard to say. It would help to know what the existing camber readings are. Have you ever had an alignment and do you have the print out?
There are front camber kits available. They are made by Specialty Products. You can often find them on eBay for about $100 a pair. The struts must be removed to install them.
There used to be (and I think may still be) a good explanation about the need for the camber kits in the BAT catalog. Look through the suspension section.
