Have any of you guys seen or know what the process that is taken into consideration for installing a Hartge Rear Spoiler for the E39? Like im saying how permanent? Does it clamp to the trunk somehow, cheap 3M tape, or is there drilling involved? Just wondering

I'm not sure which one you're referring too.. can you post photos of the one in question? If it's the one I'm thinking of, I BELIEVE it requires drilling.

Well i cant post a url yet...

But the wing is similar to that of a stock E34 sport wing, w/o 3rd brake light
