i put the splitter cental and cut two rectangles out in the bottom of the bumper and clipped the two luggs in like they are suppost to be for on the leon cupraR's it looks alot better than trimming them down as if you stand back you can see they have been trimmed then buy plugging the two lugs in start drilling from centre out wards bending in the process then when fixed up cut and trim the edges job done!
