The BMW M3 officially turns 40 in 2026, and to celebrate four decades of pure driving dynamics, we are giving away an absolute monster of a build to one lucky customer in the ultimate ECS Tuning F80 M3 Sweepstakes. If you ask us, the F80 chassis represents the peak of BMW styling the last truly beautiful M3 generation to hit the streets. To properly honor this milestone, we pulled out all the stops to build the ultimate S55-powered street and track machine.

Powered & Planted by the Best in the Business

To create a sweepstakes prize of this caliber, we joined forces with the industry’s most respected European tuning brands, heavily anchored by our three premier partners:

• DINAN Performance: We completely transformed the car's driving dynamics with a massive catalog of DINAN hardware and software. From the DINATRONICS, carbon fiber intake, throttle booster and upgraded sway bars, this M3 breathes better and pulls harder.

• LIQUI MOLY: With heavily increased horsepower, protecting the S55 engine is a top priority. We trust LIQUI MOLY exclusively to provide industry-leading fluid protection and keep this twin-turbo inline-six running flawlessly.

• BILSTEIN: To carve corners with precision, we planted the F80 on a premier set of BILSTEIN B16 Damptronic Coilovers. This setup delivers a menacing, aggressive stance and track-focused handling while seamlessly retaining BMW's factory electronic damper controls.

The Ultimate Supporting Modifications

A build this extreme requires top-tier components from front to back. We unlocked an aggressive exhaust note with an AWE Catback system, drastically dropped operating temperatures with a full lineup of CSF Cooling upgrade, and gave it massive stopping power using EBC Brakes.

To bulletproof the drivetrain, we installed Vargas Turbo crank spline protection and locked everything down with 034Motorsport mounts. The car sits perfectly on a stunning set of APEX wheels, and to ensure it turns heads before you even hear it coming, our friends at Superior Graphics in Hartville, Ohio, wrapped the car in a jaw-dropping custom livery that was designed in house by our own graphic designer Frank .
