Lots of threads on this. They aren't the same. The LCI headlights from the regular 3 series will not fit our M3's. Your only option is to go aftermarket on your car.
If you go OSS, it'll look even better than OEM. But there is a cost involved, of course. LUX and AiB are good options and cheaper, but aren't as uniform or bright as OSS.
