Thule roof-system load bars 400XT aero feet, faring, and SideArm bike rack (allows easy loading) from my 2004 S4 sedan. NEVER used the Sidearm system and had the bars and faring on for 2 weeks - then removed and stored. Essentially brand new. Cost over $500 but will sell for $300. Check Thule.com for exact fitment. Pickup from Boston, MA area; email peden@endicott.edu if interested.
