The whisper bar is a great rail system for vehicles with preexisting side rails. The whisper bar fits securely and flush with the side rails. The bar itself is very well built and has a nice aerodynamic design, very similar to an airplane wing. The bar also comes preassembled and is really easy to put on. I bought the Yakima Fatcat snow clamp to on the whisper bar and it fits great and has a great overall look.
