Took the car back to alignment shop, which has a great reputation. He went through a number of exercises and believes the car is pulling because of a tire pull and not related to the alignment specs. My question is, if the car did not pull prior to putting springs on it, and now it does, could the lower stance/spacers cause a tire pull to now appear? I also replaced the rears at the time of spring installation, fronts had plenty of tread on them. All tires were balanced. This is driving me crazy!
