Material & finish is good but fitment is not perfect
Finish and quality of the carbon fiber and clear coat seem to be excelent but at least the part I received had no perfect fitment at all.
Left front edge is not flush with the upper side of the trunk (while the right side is) and the bottom line all across from left to right (above the rear emblem) is not flush at all and has a gap of more than 5mm.
I had the feling that the part itself had a twist from left to right which caused it to be winded and therefore not ending up perfectly flusch on the top of the trunk.
For my application on the track car the price to quality ratio is perfectly fine but if one is looking for the perfect match on his show car - you will have to look for a more expensive piece or buy the PP I spoiler directly from BMW.
