The Yakima Mighty Mounts fit both my car and my kayak carriers perfectly. They were quick and easy to install and didn't require special equipment. It can be confusing to choose mounts so make sure you use the Car Rack Configurator at the top of this page or on the Car Racks page through the links to the left to figure out what will work for you. You will also need a set of 4 mounts per thing you're putting on your car. For example -- if you're going to carry a kayak with a cradle on one end of the boat and rollers on the other, you will need 2 sets of Mighty Mounts.
