[X5M50D]

Had mine installed now for nearly three years and it's still looks great.
The front splitter has slightly come away from under the centre bumper (self tapping revert popped off) but its still secure.
If I was to install this again, I would probably go with a better rear spoiler as the Maxton one is not quite big enough for the X7.
When the X7 is clean the gloss black finish compliments the gloss black trim on the X7.
For the price you cannot go wrong
