To help us over the weekly hump, the German tuners from AC Schnitzer have just revealed their latest kit for the BMW 4-Series GranCoupe. Aptly named the ACS4 Gran Coupe, this BMW kit "perfectly combines the sporting performance of a coupé with the comfort of a saloon," which is just fine with us. This aligns with BMW's usual ability to perfectly combine style and engineering, bringing together a more powerful engine with plenty of visual tweaks. Under the hood, this version of the 428i now produces 294 horses while the 435i generates 360 HP and the diesels, between 218 and 360 hp. To the eye, the BMW 4-Series will be riding 40mm lower on 18- to 20-inch alloy wheels with a sports exhaust system with chrome tailpipes poking through a new rear diffuser. A new front spoiler, optional carbon fiber mirrors and side skirts, and new aluminum pedals round out the kit. See more angles after the jump and let AC Schnitzer know if you're interested.
