I bought this as an upgrade since we bought the Toyota Sequoia which is wider than my older Mercedes GL. I also ordered the Thule Outrigger which works nicely with the cross bar to load and unload our SUPs easier. The combination works very well. I offer a suggestion I did which also worked well with me. If you want kayaks or boards to roll easily over the cross bars and without scratching try this: Go to Home Depot and buy two 30-40" long (depending on the width of the car top) of 1.5" diameter PVC pipes and two-2" pipes of the same length. The 1.5" will fit inside the 2" pipe nicely and the cross bar will fit into the combination (through the 1.5" of course) very well. This will give you a very nice set of rollers for the two cross bars and if you buy the black color of pipes they will look very professional at a cost of less than $15. I tried so many commercial covers and rollers and nothing worked better than this home made one.
These are working great so far for a Cargo Box and Canoe mounts on top of our 2017 Subaru Forester. I was leery about these as they sit up a bit higher than the factory crossbars, but the AeroBlades live up to their namesake. Without a load on top, I don't hear any extra noise with them installed and our mileage appears to be spot on with what it was without any cross bars installed. The vehicle's computer calculated ~35.2 MPG doing 70 on the interstate with some front and tail end driving on the streets with a local commute. That's is right around what the vehicle gets without cross bars. If there is a difference, we're talking a difference of decimal points. I had thought for sure that the MPGs would take a beating at highway speeds in particular with cross bars. The only con that comes to mind is that with the Cargo Box (Thule Atlantis 1600) on top, we can't pull into our garage door as it's just a bit too tall. The factory bars, which would sit lower by about an inch or two would likely allow for it, but then we would lose the ability to mount the canoe as the width of the mounting space on the aluminum is significantly reduced with those. With these, you can use the full top of the bar for mounting with the T bolts as well as wraparound accessories. The factory Subaru cross bars only accommodate wraparound accessories as there is no slot/channel for T bolts. For our vehicle, at the foremost mounting point on the roof rails, the spacing between them is 39". The foot packs underneath the bars do come inward a bit, but the usable space between the foot packs for wraparound accessories on the front bar is right around 36" (less on the rear bar), which is more spacious than what the Subaru cross bars would allow for. So far, we are very pleased with this setup!
Choose aerodynamic roof bars for superior performance and a sleek, sophisticated look that complements the lines of your car. These roof rack cross bars also have many smart design features. A textured surface disturbs the airflow and greatly reduces wind noise. The aluminium extrusion creates one of the strongest load bars in the market. The design gives you quick, no-hassle installation. While the end cap pivots and T-track make it easy to add further loading options.
