I've got a 2002 WRX Wagon with 162,750 miles. About the only thing in the way of mods is a fairly new dual core aluminum radiator. It was never raced, and I gave it to my wife when we got married (I drive the truck). She drives it even easier than I did.
I used it to make a quick run to the store this evening and noticed a sound like the car had snow tires as I would get up to about 30 mph. It didn't get significantly worse at speeds up to 60, though the pitch did increase some. I check the tires to see if there was something goofy with the tread, but found nothing. It is late enough that I didn't get underneath, but thought I'd check here to see if anyone had any insights. There have been answers to a bunch of questions over the years, so thank you all.
