Kicking off Summer with a whole new look.

Striving for a different look than anything else on the road, we present the first AC Schnitzer ACS4 build in the US.

AC Schnitzer is a well-respected name in the BMW tuning world. For 25 years, AC Schnitzer has opened the door to superior vehicle technology from motorsport for committed BMW and MINI drivers. Free from the compromises of mass production, ACS develops custom components which meet the highest standards of perfection. At AC Schnitzer, this exclusive dimension of dynamic driving pleasure is seamlessly combined with the unrestricted suitability for everyday use provided by series production, ensuring maximum efficiency of resources.

The EAS/ACS4 build is different than anything else on the road today. Most noticeable components approaching your rearview mirror will be the ACS Carbon Racing Front Spoiler & Splitter package with Carbon Side Wings, giving it a menacing appearance. ACS Carbon Mirror Caps and M-Performance Side Blades take care of the sides, while the ACS Carbon rear wing and differ take care of business in the rear. IND's Austin Yellow prepainted reflectors rid of the ugly factory amber reflectors.

Wheels are AC Schnitzer AC1 Lightweight Forged in 20x9 and 20x10, wrapped in Pirelli 265/30-20 and 295/30-20P Zero Nero Tires, lowered on KW 2-Way Coilover Clubsport Suspension. Braking duties are handled by Sparta Evolution's newest TS260X/TS240X 6-Piston front 380mm BBK, with 4-Piston rears finished in Stealth Grey anodizing.

The EAS/ACS4 is no slouch. ESS Tuning's Stage II Turbo Upgrade resides underneath the hood with Eventuri's Carbon/Kevlar Air Intake System and Evolution Racewerks Aluminum Charge Pipes making close to 600whp on EAS's in-house dynojet. Exhaust note is handled by Evolution Racewerks Catless Downpipes and Akrapovic Evolution Titanium Exhaust.

In the cockpit, Sparco's newest SPX Seats were installed, with Matte Carbon finish on the rear. Awron handles a constant display of engine vitals, all controllable through the steering wheel buttons. Macht Schnell EVC module handles manual control of the exhaust Valves at the touch of a button, as if it were a factory option to keep things subtle in town, and open up to unleash the roar when the need is there. Carrying the ACS theme in the interior, the e-Brake handle is replaced with ACS's Blackline version. ACS Floormats and aluminum pedals are also installed. BMW's uber-thick GTS Steering wheel w/ PedalHaus Black Aluminum billet shifter paddles complete the look. EAS's own coding services keeps the dashboard happy with the newly installed pieces and opens a bunch of new options not offered in stock form.

BavSound handles the audio side of things, taking care of the muddy bass and tinny highs present from the factory system. Dropping into the stock locations, it performs while remaining hidden behind the factory panels.

Very nice looking track car. That is if money is no object and you never plan on driving it on the street. That front lip would last about 2 days in one piece..
