Default Roof leak??

So after a rain when I drive I get water coming in at the end of the short seal middle on top of the side windows. Both sides. Anybody else? Solutions? Thanks.

Those seals can be seated improperly (has happened to me), reseat them and you are OK.

ALSO:
It can be that the seals are dried out due to UV exposure (keep Roadsters in the garage, not outdoors, do not buy a roadster that has been sitting outdoors, as new parts are no longer available.)
It can be that the window's travel adjustment is off, the service manual details how to adjust how far UP the window goes.

The widows can be adjusted inward to fit up tighter to the seals

Not leaking in the rain. Leaks after whe cornering or going up a hill. Like the seals are filling with water.

Then the seals are filling up with water, because they are not seated properly or have decayed. Look at the seams between the seals, they must be TIGHTLY pressing on one another.
Look at where the seals meet (yellow arrows) if there are gaps, your seals should be replaced. Unfortunately, new parts are not available.

Any Roadster not kept in a garage and out of the UV will have issues like this eventually. UV is ROUGH on those seals.
My Graphite was outside the last four years of it's life and I noticed drips at times just before the car was lost in an accident.

Perhaps you can "build up" the ends of the seals with RTV or another compound.

This is for Mercedes SLK but the Crossfire is similar, you'll have to remove the door panels. Here's a video

The window can be adjusted up, down, in, out, forward and rearward.

I"d bet you $100 its not the windows. Iv'e seen this before, both with my Graphite and my SE, the seals can fill with water if not seated properly (My issue both times) or if they have deteriorated.

Messing with window adjustments cannot compensate for this, IF it's the seals. Tread carefully.
