It's so much work to retrofit, I'll only go with the best components that I can get now.
Those pics demonstrate a few points where the Morimitos are much better. Those eBay units certainly are wiiiiide though!
Litronic is good because with acceleration and braking the cutoff will remain below the eye level of incoming traffic. But I've always thought this pales into insignificance compared to how long oncoming traffic have to deal with HID brightness due to undulations in the road so I'm with you Ger...not fussed.
Have you considered the Panamera LED w DRL's? I'm not sure but I suspect they'd do very nicely?
Oh, and remember that your deambered sections will be a couple of mm lower than the adjacent quadrant and headlight lenses. Probably no big deal (I've never seen them in the flesh).
Whatever you do, can't wait to see them!
