splitter

I've got a Astra H Sxi 3 door 2006. I recently purchased a XP front splitter, however I can't attach it on. Near the wheel arch there is about 1-2cm gap between the splitter holes and the wheel arch ?? How do I fit this on proprerly. The splitter is genuine and is off a SRI 3dr Astra. Please help

Hi, guys, On my astra h ive got the xp kit. but i want the front end to be lower. its already on springs etc, i just want the bumper to be lower. are there any attachments out theire to add a splitter on my splitter?? as silly as it sounds!! ive heard about the seat cupra splitters and know that...

Hey peeps, Just after some opinions, You know the astras without the xp kit get a lovely plastic front splinter lol It comes in a typical plastic grey / black sort of colour. Do you think it would be a good idea to colour code this? Anyone done this? Cheers!! :)
