Excelente producto, recomendado al 100%

Just be mindful that “compatible with” does not mean “exact fit.” Did not fit perfect on 2018 STi.
Amazon Customer –
Not going to give this a horrible rating because it looks like this worked well for other so Ill chalk this up to a manufacturing defect. Cheaper replicas like this usually require a few modifications to get proper fitment but this would have need some significant cutting to properly line up with the body. I would have expected mould lines along the length of the part but there were perpendicular mould lines every few inches along the entire length of the part, some of which were already causing cracks.

Not exact fit so you’ll have to work with it a bit. Nice look to it though
