I did a LOT of research and testing before deciding on these bars. We purchased these for our 2013 Toyota Rav4. The OEM Toyota cross bars seemed like an afterthought on the part of Toyota so those weren't an option for us. I'll list some of the pros of going with the Thule AeroBlade Edge bars over the OEM Toyota bars:-- The AreoBlade Edge bars strap on to the side rails where the OEM bars use a pressure-type screw to secure themselves to the side rails.-- AeroBlade is rated to hold more weight (but you still need to consider the manufacturer limits for weight).-- The plastic "feet" (that's the part on either end of the bar that connects to the side rail) on the OEM bars extend too far inward on the rear OEM bar. That is, the usable surface of the rear OEM bar is really only about 20" where the Thule AeroBlade Edge bars have smaller feet and can accommodate our very wide Thule Cargo box.-- Appearance. I know this is subjective but I've yet to find someone who doesn't like the look of the AeroBlade bars on our Rav4. I honestly think that these look more like they belong than the Toyota bars.-- T-track capability on the AeroBlade bars. I have not utilized the T-Track *yet* but I plan to do so. There is no similar functionality on the Toyota crossbars.The other benefit of these is that they accept our older-style, U-shaped attachment for our Thule Evolution 1600 Cargo box... and they fit PERFECTLY. These bars are almost completely silent on our Rav with the sunroof shade closed (any bar you put up there will make *some* sound). One of the best aspects is the lower profile of these bars. I tried another style of Thule bars but the feet and bar stood up off of the roof so much so that I couldn't pull in and out of our garage with our box on top. That may not be a big deal to some others but for me it is since we tend to come home or depart for trips late at night. I don't have to be fidgeting around in the dark! I can just pull right in. If another Rav4 owner is reading, I would be glad to send you measurements that I took in regards to implementing these so you can see if your box will fit through your garage opening.Finally, I must say that the customer support I received from Thule has been great! I have had these bars for 7 months now. I had a COSMETIC flaw on one of my bars and within a few minutes on the phone, Thule customer service was making it right. For a COSMETIC flaw... one that does not even impact the usability of the product!I would highly recommend these to anyone looking to add more utility to their vehicle. I am not affiliated with Thule in any way whatsoever but I would be happy to answer any questions that I can in regards to these bars. I know they are expensive but it's my opinion that you get what you pay for in regards to these types of accessories and it's well worth the cost for the added utility and even the added looks!!2 year update:I'm happy to report that after 2 years of these being on top of our Rav4, They are still in great shape. These seem to have held up great. I just transferred them to our new Toyota Sienna (2016). I was worried that they wouldn't fit since the Sienna is larger but the same size (7502) ended up fitting on the Sienna van. I haven't yet driven with them on to comment on gas mileage decline or wind noise but my wife hasn't said anything about it. I'll update if it's a real problem. Added a photo!
