VOS GmbH has come up with a meaty upgrade package for the straight-six twin-turbo engine that powers the BMW M3/M4 models, boosting the power output from 430 to 550 horsepower. Thanks to the extra oomph this VOS BMW M4 you see here is now a 310 km/h car.
VOS does not get into the details of the power kit, saying only that it makes 550 Nm of torque. What they like to talk about is all the other little upgrades they have fitted to the VOS BMW M4 which they believe is one of the finest tricked out M4s out there.
The car gets a set of Clubsport Variant 3 coilovers from KW for 4.199 Euro, a stainless steel sport exhaust system complete with silencers and rear muffler for a whopping 4.890 Euro, and six-piston Brembo calipers with 380×34 mm racing brake discs on the front costing 5.425 Euro and 380×28 mm discs out back for 4.425 Euro. The engine upgrade kit is 2.900 Euro.
Visually, the Austin Yellow VOS BMW M4 gets a carbon rear diffuser for 799 Euro and carbon mirror caps costing 599 Euro, plus a set of BBS wheels in sizes 9×20 and 10.5×20 inch wrapped with Vredestein (255/30-20 and 275/30-20) priced at 4.595 Euro. To be honest though, all you ever need is that engine kit. The rest is extra garnish you can do without.
