This 2020 X3 M40i is a comprehensive blend of performance, audio and chassis upgrades. BimmerWorld Brembo big brakes and multiple Ultra Racing bars tighten handling and stopping power, HR lowering springs sharpen body control, and MHD tune frees up the engine’s personality. Cold air intake, turbo inlet and Paradigm bits help breathability while the Alpine sub and amp address cabin sound. Practical touches like paint-matched reflectors, a stealth hitch and a dash cam round it out. The end result feels like a daily that’s ready to hustle on demand.
