The fitment is very nice for the side! I didn't heat up at all and it fit perfectly. The only thing that is soso is the upper art of the bumper. It isnt perfectly straight even with the metal bracket. But I didn't try to heat it up yet. I'm gonna try this summer to straight thing up with a heat gun as recommanded. Overall, I'm really satisfied with the result.
Also the mold that made the bumper is really really high quality. You have all the details and bracket for the mesh.
