Exotic materials make for a fun time on the track.
In the performance car world, weight is king. It can make or break a car’s performance whether it’s the amount or the way it is distributed. The team at Lightweight knows a thing or two about trimming down the fat, and their name reflects that. The latest victim of the petrol nutritionists is the new BMW M4 and it may have lost a few pounds, but it gained a few goodies.
One way that the German tuners are able to cut weight is through the use of titanium. They used the special metal to create a full exhaust system with valve control to optimize backpressure while also giving the drivers the ability to alter the exhaust note. The titanium exhaust featured on the LW BMW M4 was designed specifically for the car and reduces weight compared to other stainless steel units. After being paired up with a new ECU tune, the twin-turbocharged inline-six cranks out 520 horsepower and 479 lb-ft. of torque.
Next up for the LW BMW M4 was the body. Here, Lightweight didn’t want to add a great deal of weight while trying to optimize the coupe’s aerodynamics, so they opted to use carbon fiber. Up front sits a spoiler blade in visible carbon while an adjustable rear wing piles on the downforce for the rear axle. These two components are able to generate more stability than stock without adding unnecessary weight to the M4.
With the added downforce and more ponies pumping through the rear axle, Lightweight got to work on the chassis. The factory wheel and tire setup was swapped out for a set of new BBS RI-D wheels measuring 9.0 x 19 up front and a wide 10.0 x 19 at the rear with grippy 265/35-19 and 285/35-19 Michelin Pilot Sport Cup 2 tires sticking to the asphalt. Behind the wheels sit new four-piston calipers and endless brake pads on the front and rear axles. Rounding out the chassis is a new Bilstein Clubsport suspension that gives handling that extra boost in the corners.
In the future, the LW BMW M4 will be getting the full racing treatment with new bucket seats, a full roll cage, greater weight reduction, adjustable spoilers, smooth underbody, and more.
The featured Lightweight LW BMW M4 in its current state will set you back 89,000 Euros for the complete vehicle and all of the modifications.
