One of the true joys of having a new and popular BMW M model released is that there are a lot of enthusiasts building their cars right alongside yours. Some end up very similar, yet with small distinct touches. Others might drastically diverge into worlds apart – and this concept is the basis for what you see here today. Yes, if you are wondering, we did struggle to resist the usual “ketchup and mustard” references!

While the team here at PSI knew well in advance that our M4 Club Sport project was bound for SEMA and beyond, through several drastic evolutions, our friend Joe started with an entirely different car, and then continued on his own path. While there are a few basic similarities between our two approaches – mostly in that they are both the current F8x platform – in some ways you couldn’t ask for a greater contradiction. At their core, one is a yellow four-door M3 with manual transmission, and one is an orange two-door M4 with DCT. Night and day comes to mind.

If anything, our opposing processes and styles prove yet again that creativity plays a large part in the art of modifying a car, and two end results at opposite ends of the spectrum can certainly be appreciated by everyone involved. Rather than finding yourself stuck in the rut of having largely the same modifications as several others, realize that there are an ever-growing combination of colors, brands and variations out there – certainly far more than we have installed on these two M cars.

By staging a duel here today, even though each build is worlds apart, we can find a lot of common ground between these two polar opposites. We hope you can too!
