This M4 blends track-capable hardware with subtle luxury upgrades. Mad US midpipe, chargepipes and J-pipe sort exhaust flow and reduce lag, while bootmod3 S55 tune and Bimmer Remote flashes extract usable power. Horizon Motorsport diffuser and carbon trunk lip add aerodynamic focus, and Madtrace magnetic paddle shifters make downshifts satisfyingly immediate. Supporting bits—Dinan drop-in filters, Vargas crank bolt capture, anti-theft throttle commander and a baffled oil catch can—show attention to reliability and daily usability. Overall it’s a well-rounded M4 that’s ready for track days without sacrificing street manners.
