After a bunch of research, I ordered the Thule 450R feet and 53" Aero bars, along with a 6-pack of lock cores. I paid more than I wanted to for a basic roof rack but got a great deal from Rack Attack and now that I see the set up on the vehicle, I am very happy with the purchase.
My first exprience w. Thule products. I find them to to be well engineered and made of high quality material. The kit is easy to install, extremely sturdy, and looks great on the Highlander...color scheme even matches. Road test up to 50mph produces some minor whistling but indiscernable with the moon roof closed...we'll get it on the interstate later this week and see what happens to noise and mileage.
Thanks to Walter and the team at Rack Attack for the prompt service and attention to followup questions I had.
