California-based tuning house TAG Motorsports is known for putting together some pretty wild aftermarket packages, and this BMW M4 is up there with some of the best of them. Wearing Vorsteiner's GTRS4 widebody kit, the hi-po coupe also boasts wide fenders, an aggressive rear diffuser, beefy side skirts, a prominent front splitter and an M Performance deck lid spoiler and mirror caps finished in satin carbon.

A titanium exhaust with carbon tips come from Akrapovic, there's 20-inch HRE rims finished in brushed titanium, while performance mods include an AWE Tuning carbon intake, an ESS ECU upgrade for the 3.0-liter twin-turbo V6, and a Bilstein Clubsport coilover suspension.
