You are in luck. Inno Racks now has a Hyundai Elantra Touring roof rack system. It is the Inno IN-SU roof rack system. It mounts to your Hyundai Elantra Touring naked roof top. You'll use the Inno K573 Fit Hooks and the Inno B127 50" length cross bars (these components are all included with the Inno IN-SU complete roof rack system). You can then attach any cargo roof bag to the IN-SU base rack system cross bars.
An excellent roof bag is the Inno BRA120 Flex Top 18 roof bag. It supplies a ton of room for all your camping equipment luggage etc. And if you ski or snowboard in the winter you can use the Inno BRA120 Flex Top 18 roof bag for carrying snowboards and skis as well.
