There is not much one could say against the design of the brand new M4, as it clearly shows a “natural” progression of BMW’s design language, one that has yet to fail.
Thus, some M3 owners might want to upgrade to M4, but lacking for money, they have to contend with what they have.
Then again, why should they? Why not just try to upgrade bits and pieces of the M3 to mirror features from the M4. This is the line of thought I believe OSS Designs used when they came up with a very interesting option.
They offer for any E92 BMW M3 owner the possibility to upgrade the headlights to a very nice version of the M4 Corona Rings. And while the shape of them is quite appealing on their own, the aftermarket specialist deemed necessary to ad a nice twist to them. They change color at the simple push of a button. A remote control button, at that. From blue to pink, you get whatever strikes your fancy, and should you grow bored, just switch to another.
