so there are 3 types of roofs on the DT's... the no sunroof model has an extra raised rib right next to the trim molding that runs above the doors from the front to the back, this is the only model that this spoiler will fit. The sunroof model and the panorama roof do not have that little extra raised rib, therefore at the ends of the spoiler there will be a gap between the spoiler and the roof line. I am sure with a little sanding, hacking, body filler on the spoiler itself, that you could make it fit... but from the manufacturer it will not, and yes its a noticeable non fit.
