At ReRack we only sell racks and parts from top-quality manufacturers like Yakima, Thule and Rhino-Rack. These roof racks are typically able to support more weight and gear than standard factory racks. The price of a base roof rack will depend on if you want new items or not, aerodynamic profile or not, and your vehicle year/make/model. There are complete roof rack setups starting under $150 for a used rack on older vehicles, all the way through $500+ for a new, aerodynamic top-of-the-line setup.
Although this item might be the only choice for putting a roof rack on some cars, I don't believe that it is much of an option. I'll admit that the dealer warned me that he didn't have a very high opinion of it. He also told me he wouldn't help with the installation and that furthermore, if I wasn't happy with it, everything else BUT the Thule 477 SRA was returnable. Being a hardheaded sort of fellow, I had to find out for myself. I'd like to blame the dealer because he probably should'a refused to sell the darn thing to me but truth is, that would'a made me even more madder!
Aluminium bars include T-track slots which allow you to use the full length of the bars for load carrying. The WingBar not only looks good but more importantly includes a device which reduces wind noise to the minimum, as well as reducing drag. Many customers leave their Thule WingBars in place from week to week, especially if they are taller vehicles and fitting is awkward.
