Has anyone tried using a spacer under the rear of the Targa top, say about an inch or two to make a vent? Since my top has to be and is bolted down in the rear I thought this might help break the vacuum that forms behind the rear window? I have seen a couple with plexiglass/lexan rear windows with several holes across the width which would do the same thing I think?

The only "fer sure" solution I've seen was an airfoil section (cruved about 90 deg) bolted to the roof , directing the air down to the grill. The guy that had it said it dropped the engine (4 banger) temps 20 deg at track days......the high drag solution (IMG:style_emoticons/default/biggrin.gif)

Is rear glass required by your sanctioning body? If not...
