"car is still pulling to the left a bit at high speed... "
Love your write up man! Glad im not the only one sinking money into these cars lol. My car exhibits a lot of the same noises/vibrations yours does. Mine also pulls to the left on the highway, which my automotive instructor told me is completely normal and caused by 'road crown' not the car's alignment. Ive done my alignment at school twice after getting new tires (Dunlop Direzza 102's) and it was completely in the green so i think the fact that the protege's steering rack is so touchy it makes the pull at high speeds seem a lot worse than it is. BTW those direzza's are great tires and cheap! (~$76 a piece USD on tirerack) they're summers but i live in St.Louis, MO and we get some pretty random weather across the board; ive seen almost every road condition in the course of just a couple weeks. In the snow they do great for being summer rubber, they communicate really well when their going to break loose.
