Everything still feels pretty tight. I'll probably get under and check bushings and front end parts when I do the belts and hoses soon (I think I have them in my garage already.)
I have only used performance tires. I'm running the Michelin Pilot Super Sports right now, and I do like those pretty well.
I forgot to mention in the original post, I got 22.4 MPG on my trip to Alabama last weekend. That has my worried... I don't think I've ever gotten more than 20.5 before. Maybe I just lucked into a tank of gas without the ethanol crap in it.
