Not many choices, but the Yakima Q Tower system with Q 46 Clips will do the job, pretty good considering the koup has "frameless" doors.
I suggest you get it professionally installed so that the Q 46 clips hitting the glass is minimal. If you're very technical and you decide to buy the system, the instructions don't have the Koup listed but here's the measurement: M1 - 45 1/4", M2 - 4", M3 - 43 5/8", M4 - 21"
WARNING: If you have a sunroof/moonroof system, you can still open it to vent, but to fully open you need to get the Yakima stretch kit, otherwise fully opening the sunroof hits the rear bar. I didn't get the stretch kit because I only plan to use the roof rack seasonally.
Here are pictures of mine, seriously there are those that aren't gonna like roof racks on the koup, but hey my car, i got $$$ to throw, and i need the space...oh yeah fashion over function ...peace!
Best to make sure...you would have thought the Spectra sedan and Spectra5 shared everything but the rear body parts -- but they did not. The performance exhausts that Kia provided was different between the Spectra sedan and Spectra5.The hitch for the sedan and coupe are 2 different hitches so Im waiting until one for the hatchback is officially released by someone. I did look at the instructions for both hitches and the coupe one seems to be the correct one but Im waiting just to be sure.
