deal with this one, because i traded it straight up for the hipers. the stillens are definitely quieter than the hipers, for sure. as far as torque is concerned, it does feel a bit stronger down at the low end, but it's not a night and day difference. it's really hard for me to tell objectively now because the temperature is dropping and it feels like the car has so much power now...lol. but thanks for all your advice on the issue. much appreciated!
