2015 BMW LW M4 by LightWeight Performance Packs 520HP and GTS-Previewing Chassis and Aero

LW M4 gifThe 2015 BMW M4 is stunning and packs 425-horsepower from the factory.

But is there room for a more track-focused version? BMW M certainly thinks so — the upcoming M4 GTS model is nearly complete after running extensive testing around the Nurburgring.

Lightweight Performance of Germany has beat them to the punch, however, with its new LW M4 upgrade. This includes nearly the whole catalog of LW upgrades, including engine tuning, wheels/tires, suspension mods and exhaust changes.

The combination results in 520-horsepower and a far more focused look on the outside. Aero upgrades are comprehsive and include a racing-spec rear wing that looks much like the M4 GTS test cars.

The lightweighting program is pretty comprehensive at stripping the luxurious M4 down to its raw performance bits — with the result being quicker and more-intense laptimes and track performance feel.

If the economy of weight is first of all when carrying out a tuning, the name of the firm LIGHTWEIGHT directly corresponds to this task. The enterprise of firm located in Mittenaar to the east of Herborn of the Hessen State mainly specializes in on the individual development and production of titanium exhaust system. All exhaust systems are produced by using modern CAD technology from specially alloyed titanium which exclusive right of use in Germany belongs only to LIGHTWEIGHT.

It is natural that the whole equipment park is on state-of-the-art technological level. The titanium as noble material is characterized by high resistance to corrosion, unusual durability and small weight and therefore concerning the price is noticeably above quotations of stainless steel.

In this case the LIGHTWEIGHT team under the leadership of the executive director of Marc MÜLLER reduced the mass of BMW M4 Coupé and logically referred to as LW M4. For more performance is LW front spoiler blade responsible optionally available from visible carbon ore PE, stepless adjustable carbon rear wing, and a trump ace -the LW exhaust system inclusive. Valve control (is also in stainless steel available) as well as brake system with 4 piston saddles and endless brake pads on the serial discs at front and rear axle.

By the way, a genial wheel and tyre combination from the RI-D rims of BBS in 9×19 Inches with Michelin PilotSportCup2 in 265/35-19 (VA), respectively in 10×19 Inches with 285/35-19 (HA), is combined with Bilstein Clubsport chassis. The engine of the bolide delivers super strong 520 hp (= 375 kW) und 650 Nm of maximum torque tug at the crankshaft.

It is also planned in the future to trim the LIGHTWEIGHT M4 more in direction of club sport. The safety cage, bucket seats with six point safety belts, one more considerable weight reduction, the adjustable front spoiler blade, carbon rear diffuser, a spoiler lip on the boot lid and an enclosed underbody are the appropriate measures for this goal.

The complete modification has a value of 89.000 euros!
