Dave,

I'm not certain, but I think that if water gets under the foam (e.g. where the top seals against the clam shell under the rear window) it would not necessarily go to the drain holes. If it did, why would Porsche have installed the foam liners?

Here are three ideas:

1. If you have not already done so, seal or plug the drain holes at the bottom of the foam liners and check to see if the water is seeping through the side of the liner. There may not be an obvious hole, but there could be a few pinholes or worn areas that leak.

2. Check the condition of the weather strip that fits between the rear of the top and the clamshell.

3. Check the gap between the rear of the top and the clamshell when the top is up or closed. It should fit tight.

Also remember that there are drains in the front of the car too. You seem convinced that the water is coming from the rear, but you never know.

Good luck.
