I would personally seek advice on this Chris m8tey.
The spoiler is held on by strong glue (as far as i am aware) just like the Pug 206 GTI... people steal Gti spoilers from pugs as they can be ripped off easily... i think the

are the same.
I wouldn't try and put anything through the gap inbetween or over the top as the forces might damage ur spoiler or car.
I advice you go to your local

dealer and ask... This wont cost you anything and may prevent you damaging your car and having to pay for it.
Make sure its first of all 100% safe to fix onto the

with the spoiler, and secondly, it wont cause any damage. Good Luck with it m8.
