The fit of tires is unfortunately an inexact science. I have had many 1st gen camaros, and they are not exactly precision instruments. First off, as Bret says above, add some neg camber. If you are just puttering around, it will reduce tire life, but if you ever autocross the car or run it hard, you will wear out tires well before you run the inner edges off with lots of neg camber. There is a guy that autocrosses a 67 camaro in an SCCA class where he is restricted to completely stock parts and he uses neg camber in the 5-6 degree range. It is so much that the front end looks broken.

Second, replace the lowered bushings. Every fraction of an inch counts, and a half inch will definitely help.
Third, it goes without saying that adding a inch or so to a normal backspacing measurement will make inner part of the tire contact the frame sooner. It will reduce your turning radius, but I bet you will probably be able to live with it. You won't actually be making 3 point turns into parking spaces.
Lastly, the stock type inner to outer fender bolts will have to change. It won't kill anything to leave them out, or preferably use something with a flat rounded head.
There is lots of misinformation floating around about the tru-turn setup. It is an excellent product for eliminating bumpsteer, lowering the car, and getting the steering arms out of the way so more BS can be used. It is not an always foolproof method of stuffing the wheelwells with rubber. It looks like your car hasn't been painted yet, so you still have the opportunity to do some minor mods inside the fender and it will be smooth sailing. That is until you change tire brands and the next set in an identical size hits, tires themselves can vary nearly a half an inch from brand to brand.
