Vorsteiner BMW M4 GTRS4 is Spicy Mustard
Considering all the amazing work Vorsteiner did to the last generation (read: E92) BMW M3 coupe over the last few years, it’s hardly earth-shattering news that the SoCal-based tuning house has given that model’s successor – the BMW M4 – a similarly comprehensive makeover. But that doesn’t make the Vorsteiner GTRS4 any less impressive of an achievement; the wider fenders (by 4” at the front and 7” at the rear) transform the already-athletic F82 into a vehicular MMA fighter, complete with revised fascias front and rear and a quartet of 20” three-piece forged wheels (measuring 13.5” wide in back!) stuffing the aforementioned fenders.
Best of all, Vorsteiner’s tinkering didn’t end on the surface; it also fitted a suspension sleeve kit from KW and an E-Tronic tuning module from ESS Tuning. That second item gooses the 3.0L twin-turbo inline-six from 425 horsepower all the way up to 550 horsepower. In other words, the Vorsteiner GTRS4 should perform the way it looks: Stone-cold killer.
