I bought the roof rack 1/2 year ago. There was an "application list" for the roof rack. The Kia Stonic is not included in this list. To my knowledge, however, the Kia Stonic is relatively new, which may be why it is missing from the "old" list ..... Perhaps it is best to ask the manufacturer "Menabo". However, I wouldn't buy the roof rack for my Peugeot myself and would invest the extra money in an original rack. Although my Peugeot is on the list, the fastenings are sometimes tilted and can only be screwed to the railing with a bit of "fiddling".....
