Review on Jackey Awesome Exact Fit ///M-Colored Grille Insert Trims for BMW Z4 (2009-2017) with M-Performance Black Kidney Grill (9 Beams) by Jason Robinson

One of the three pieces showed discoloration in the stress area right out of the box and the other two developed stress cracks where the pieces must flex during installation. Perhaps the strips needed some warming up before installation to be more flexible, but there were no instructions in the box at all. The product appears to have had a previous attempt at installation and was probably returned to the seller who found no damage. Came back for a quick refund from Revain.
