i have never installed a spoiler on a vehicle but i imagine that u would have to modify the brackets on the spoiler to match the curvature of the aveo. so maybe some bondo, a dremel, some paint, some bolts, and a lil bit of patience would be all you need. again, i really dunno how to do it since ive never done it and am not a body shop tech. hope this is right and helps you.Originally Posted by lowaveo17
