Just a small update.
I sent the projectors out to get the greenkouki custom shield mod. He creates a custom CURVED shield for the projectors because they come with a straight shield from the factory.
While the curved shield is great for achieving a razor-sharp cutoff line, it tends to distribute light poorly as it fans out. The curved shield compensates for this "flare" off to the sides and corrects it.
He is also going to be playing with the lens spacing to achieve both perfect cutoff and color flicker.
Can't wait to see what he does with them. What's even better is that he doesn't require payment until you are completely satisfied with the output pictures he sends you so he fine tunes it to your exact liking. Super nice guy and also EXTREMELY informative. I couldn't recommend him any more highly if anyone is considering this route with the RX's.
Note: If I understand it correctly, he only performs this service with RX projectors.
