I strolled into the Seat dealership last Tuesday, bought a few items incuding the Leon splitter, which was £17.63, £20.72 incl. VAT.
I didnt have much of a clue what i was doing regarding the fitting, but i figured it cant be too difficult.
Put my car on the ramp at home just to make things a little easier, and single handedly offered the splitter up to the bumber, taped it on first of all to check positioning etc, cut the centre peices out, and then used my brothers dewalt to drill through the splitter and into the bottom layer of the bumper. Making sure the self tapping screws wern't pertruding through, i just simply screwed the splitter into the bumper. Adding a few extra screws inbetween just to make sure its secure.
Few people have mentioned about not using too many screws incase you clip a speed bump or something and you'd want the splitter to come off not the entire bumper, but i drive sensibly so made sure the splitter was on nice and secure.
Final thing, just clip the ends of the splitter with some snips or similiar. I took about an inch off each end.
Sorted!
It really is simple, and gives great satisfaction when done! And im not the most practical of people, architect by trade so this make anyone capable!
