That looks exactly like the windscreen from the BMW Z3. No offense but its construction was fantastic and yours seems plain. It was completely flush with the roll bar and had 2 bent reinforcement ribs so it could sit flush and never bend. I think if you took some time to bend the lexan to fit the bottom (like an L) and trimmed it up so it did not protrude outside the roll bar, you might be competitive in the market. Honestly, I paid big money for the OEM windscreen because there were no alteratives, but your current design seems like a prototype and would not have been an option. Hope you strive for perfection, us Porsche owners can be a picky bunch.
