No the spoiler isn't incredibly heavy and my trunk stays open just fine, even when the car is pointing slightly uphill on my driveway.

Well it looks like the response is overwhelming, so I went ahead and actually installed it. It looks great! It does add more weight to the trunk lid, but once I get the new springs installed, it should be able to hold it up. Thanks fellas...

I'd say without for newer coupe trunk but with for older style coupe trunk.

Without, I like the coupes classy yet sporty look. I think the sleek look is ruined when a spoiler is put on.
