The Westcott rack sits much lower, in terms of wind noise, unlike the factory roof rack, which is notoriously loud. Interestingly, the Land Cruiser comes with a decent factory looking rack—makes you wonder what the GX550 engineers were thinking with their design.I've got a question in to Westcott, but thought you might know off-hand. Does the rack when installed stick up much higher than the OT+ rails that it replaces?
