Post lunch,,,,,,,the growl is only between 18 and 30 mph. We jacked up the car and spun and shook the front tires with no apparent play or noise. Hard to spin them very fast due to the residual caliper pressure. My tires are Goodyear F1 with about 26K on them. They have a little bit of a cupped apprearance on the front but are very smooth @ 80 mph on the highway. No handling problems, vibrations or shakes,,,just noise at 18-30. Very annoying. I did have to buy lunch,, Mexican if its important.
