2017 BMW M3

This 2017 M3 keeps the focus sharp: Signature SV104 wheels and a Dinmann carbon back-seat delete turn this from a plush cruiser into a lean, focused car. Wheels add the right visual and rotational mass savings, and pulling the rear seats cleans up weight and the interior for track days. The P3 OBD2 gauge gives live, useful data so you actually know what the car’s doing. It’s straightforward and purposeful — a build geared toward seat-of-the-pants feedback, better lap times, and a cleaner cockpit.
