    2004 Audi A6 Performance Parts Reviews

    Impressed!
    Wow! What a difference this product has made on my Audi! Heard good things about aftermarket sway bars, but was skeptical about them making any real difference since my car already had sway bars on from stock. After my first test drive all misgivings disappeared. Cornering stiffness greatly increased! Car lost that shifty/unstable feeling I would get when cornering hard. I live in the middle of the Appalachian Mountain range, so these sway bars are going to get used hard, as I love a good speedy riparound on mountain roads! :-) Definitely worth the money! Would recommend to anyone looking to farther the cornering stability and control of their car.
