I don't what components you have changed on your car, but a possible explanation would be worn bushings etc since the car is 9 years older than the original poster's...might make a difference. I know the 6th gens are very tolerant up front...usually you have to go lower than 2" before needing camber correction. On my 99 I have H&R sports using a lower perch on my Koni's...probably about a 1.75 to 2.0 drop up front, camber still within spec.

If you were eating tires, that could have been a toe issue. Or maybe the 5th gens just aren't as tolerant up front.
