The fit is great but it should be noted this is largely a function of taking your time on install. The shape of the lights is dead on. This should be expected from Osram, especially given these lights that are road legal (in some countries, US excluded). The screws used to secure the lights allow adjustment to make sure your gaps are even.
My gaps are better than factory with the Osrams but I certainly didn't take time to adjust the stock lights as the gaps weren't uneven enough to fuss with. Also of note is that the gap between my fenders and hood is slightly different side-to-side. I don't know if the hood, one (or both) of the fenders would need adjusting to fix this. Consequently, my lights are probably not in the exact same position but the gaps on the respective sides are good.
