We installed crossbars and a kayak rack onto a 2019 Tesla Model S. The setup was manufactured by Thule. The feet we used were Thule's Rapid Podium which were attached to the fix points of the car using Kit 3153, and the crossbars we used were Thule Evo Wingbar. These crossbars have channel mount capability for mounting accessory racks like the Thule Hullavator Pro. The Hullavator has a gas strut assist of up to 40lbs to make getting the kayak on the roof vehicle easier. This setup has a weight capacity of 165lbs.
We installed a crossbars onto a 1985 Volkswagen Westfalia. The crossbar setup we used was manufactured by Thule. Using the Thule Rapid Gutter feet mounts we secured them to the vehicle by drilling into the pop-up of the vehicle. Once those feet were attached we used Thule square bars to complete the setup. This setup has a weight capacity of 165lbs.
