Correct me if I´m wrong, but after viewing the pics of MS rear wing it looks like it fits on top of the OEM "lip" on the trunk... Correct? or do I have to remove the OEM one?...

 

I don't think it fits on top the OEM lip :p

I am sure you stick on the top part of the MS wing, it will fly off at 60 mph :p

There is a thick metal base at both end of the bottom lip to give a metal stick out on both sides.

No.... one good news. The holes that made from the rear trunk lid will fit the MS wing... hang on, you have an euro lip, then I am not sure :p It is true though for all US and Australian OEM rear wings

 

The OEM wing is still the same in Europe as in US... So I guess it would still fit in the same holes. Thanks!

 

Hmmm....if I recall correctly, the MS wing will not fit in the OEM spoiler holes. When I pulled my OEM wing and laid the MS template over it, it didn't match up perfectly. I believe you can still use the OEM spoiler trunk lid, as there is clearance to drill the MS holes and the lower spolier will cover the OEM spoiler holes.

As the trunk lid was scratched by the OEM wing, I just ended up switching out trunk lids with my dealer for a non-spolier trunk lid, so I'm basing my comments on my feeble memory

 

when i lined my MS wing to the oem holes, they we're a perfect match as well as the templated..
