GT3 aluminium doors - weight saving?

[Lungauer]

As a matter of probably academic interest does anyone know the weight saving of the aluminium doors from a GT3/Cayman R over standard steel ones? One of the things I think they got wrong on the GTS was not fitting these.

Thanks

15kgs I believe, based on Boxster Spyder.

Always room for more though... http://www.richardaucock.com/porsche-misses-obviou...
