you say "loud" as in wind noise as well or just your tires? I hate how loud our cars get at high speeds from wind noise we might as well have the windows down, our aerodynamics were not designed for ride sound quality that is for sure; anyone else notice that from like 70 on we can't cruise without that horrible noise?

 

my car ride really nice at highspeeds. The only thing i got right now is a bad wheel bearing in the rear soo i get a little hum and vibration.
If you guys are getting road noise it just might be the tire wear. I know when you lower the car it throws the toe of the car off and it puts more wear on the tire then when it sits at regular stance. So it may just be wearing tires that is making your humming/whining noise.

 

my s4 rides great at high speeds. World of difference form my 2000 9-5
