The Porsche Targa top has been called the 8th Wonder of the World - though some claim the 8th Curse (that being windnoise). I have identified 15 causes of wind noise and water leaks. Here is part 1.

Part 1

1.Top worn out - Cupping of material in front and/or back, with the vinyl beading sticking up creating openings to catch air or water. Top needs 4 Stage rebuild.
2.Only vinyl replaced - The two levels of reinforcement not being replaced when top was done, which causes there to be too much material creating air scoops in the vinyl.
3.Top 'un-square' - When top is rebuilt and all material is removed, top become un-square. A top off ½” will create gaps at the front and rear causing leaks. A fixture was not used during repair.
4.Top sits up in a corner - Wrong front gasket used too large, actually 964 seal. Correct seal not available since 1995 even though part # on bag is correct. I have correct seal in stock.
5.Top high in front - Top not pushed far enough to the back so beading touches the roll bar. Top needs to drop in slot in the front. Something is preventing top from siding back.
