Got my splitter the other day, started fitting it last night, and I must say i had a c*nt of a job trying to get both sides to line up, where it runs up the bumper along the arch.
I now have it fixed on the bottom of the car but both sides need to be secured and keep jumping out of place because it's such a tight fit, so i either need to bond them onto the bumper somehow, or screw them on, which i can't work out how to do without it looking rough.
