Fitting the Pro-Alloy IC means removing the foam from inside the bumper, I've noticed on quite a few coupe's this makes the centre of the bumper wilt becoming mis-shaped.
I ended up fitting an alloy U section bar along the under side of the bumper, secured by the screws that hold the front grille in place so it's hidden away.
That U section keeps the rigidity in the bumper and keeps it looking straight.
You may have to remove some plastic from the bumper at the bottom to fit the IC, I removed about an inch from the back of the lower vent hole, also shift the IC back as far as it will go on it's mounting.
You don't seem the type to get your hands dirty though so just pay someone to do the work for you
