Since I brought the car in the summer of 03 I have had 5 of the things. I bugs me like a fly buzzing round my head when it is all scuffed up. The jack is the best way to get them on makes the job take minutes and no need to lie on the ground with your legs in the air going red in the face trying to get the clip in :)!
 
Should be able to fit one on with the use of some self tapping screws!

Someone more knowledgable may confirm this, or tell me I'm wrong
 
My splitter has popped out in the front middle section iv whacked that hard the car moved!! what do you mean use the jack?? please help as its doing my head in!!!

Thanks
 
did mine today. just stick the jack head under the central support bit, and jack it up. it eventually 'pops' in. then do the other one.

i've managed to scrape it already :D
