So windows are in, I went with the 4mm hard coat. Painful process of breaking the glass and scraping out the leftovers that are glued on pretty well, but finished product looks factory.
As the quarters come they are more designed to go on without the factory seals, you need to trim them down in various spots to fit within the seal.
Almost half a kilo difference after NACA duct but I am not chasing weight reduction just air flow.
