Somthing around 30 degrees from the horizontal if I'm not mistaken.
Do convertibles benefit from even more inclined windshields than their hardtop counterparts?
Something like 20 degrees from horizontal?
Of course you'll need a pretty transparent and non reflective glass, and a really really long and dark dashboard for such angles.

If they did,the automaker may be restrained from doing it due to optical effects stemming from the steep inclination.There is a point where outward vision is aggravated by internal reflections of the dashboard on the windshields underside.
Also,the non-triangulated A-pillars would have to be more massive to deal with Federal vehicle rollover standards in the event that you went turtle.
