So I haven't driven the car on the highway in a year. Started the trip out west today. Once it gets up to 70, there is a noticeable vibration / hum coming from somewhere. I can feel it in the shifter as well as the steering wheel.

I just put lowering springs on it a few days ago, along with wheel spacers. I didn't get it aligned. The steering doesn't feel bad, although I do notice it following the grooves in the Georgia highway. The spacers were torqued to spec and I used blue locktite.

Do you guys think it might be flat spots in the tires, or do I need to get it to an alignment shop pronto?

I decided to take it to an alignment shop in the morning. I'm going to have them remove the spacers, do a 4 wheel alignment, and check the torque on the lower strut bolts & IRS cradle bolts.
