Your power steering pump might be going bad, and lowering the front end may have put a bit more strain on it and caused the noise to be more noticable. I had a problem with a noisy pump on my '97 GTP - my '00 GTP is much quieter.
Well after posting this I checked the PS pump and all the belts and seal and nothing. Its not a power sterring whine it sounds more like the line is squecking. I really can't explain but I iwll take a vid of it next time i'm in my car.
