They provide the best professional feedback with suggestions on the type of modifications you should make for your own BMW model; or they can just direct you to the best aftermarket shop.

The video below was put together by Matt Farah from The Smoking Tire auto magazine, who recently had the pleasures of driving a modified BMW 435i, which brings it closer to the almighty BMW M4 in terms of mechanics and performance.

Speaking about modifications, this particular BMW M435i comes with stock suspension and brakes, the Evolution Racewerks charge pipe, Gintani catless downpipe with Supersprint exhaust system as well as an AGE air intake, piggyback tune, and a few more with that.

There are also the wider black wheels wrapped in Pirelli P Zero rubbers which perfectly complements the colour-shifting satin exterior colour.

In the engine department, the standard BMW 4-Series 435i comes with an N55 six-cylinder engine, developing 302 horsepower available at 5,8—rom and 295 lb-ft of torque, available between 1,200 rpm and 5,000 rpm. However, with all the modifications carried out, this lad here might come with more than 350 horsepower. Unfortunately, we do not know the exact features. But until fresh details, enjoy the video with the model!

Now, the same Audi based tuner is back with another standout power project carried out on the magnificent Audi S8 Plus, a luxurious sedan which already comes with massive power underneath the skin.

As usual, ABT Sportline combines beauty with power; however, for this case, the styling mods are scarce, instead, we get to enjoy plenty of new mechanics and monster power.

The only thing that is standout at the exterior is the new set of wheels, the same from the DR or FR series, with a choice of 20- and 21-inch, adding the tuner`s most high-performance 22-inch FR wheels as well. The massive alloys look smashing with the new ABT stainless-steel exhaust system with four 89 mm tailpipes, fender inserts or integrated door entrance lights with the ABT badging.

Besides these outstanding pieces, our Audi S8 Plus also got the ABT Level Control System enabling the car to be lowered by 20 mm on both axles and providing it with greater stance and stability.

The big surprise is the power kit under the hood. The technicians from ABT Sportsline have added an ECU remapping, turbos updates and some modifications to the car`s new exhaust system, all making the 4.0-liter TFSI V8 engine extremely powerful. We are looking here at three stages of power – 675 HP, 640 HP and 705 HP. However, if you think that this ain`t enough to satisfy your appetite for speed, then you can also get 735 horsepower and 920 Nm of torque, adding a top speed of 320 km/h.

There are only few styling tweaks such as a body kit including side skirts, front and rear bumpers, new 21-inch forged alloy wheels and a two-color interior trim with new leather upholstery.

Gemballa opted for lightweight carbon fiber parts in order to cut down the weight of the model. Even the engine received no improvements or upgrade, the German tuning company mounted a new exhaust system with no less than six pipes.

This system is available for the 3.4-liter and 3.8-liter six-cylinder engines but as mentioned above, it brings no extra horses or torque.

“Lowering the unsprung weight despite going up a wheel size was a priority,” said Andreas Schwarz, CEO of Gemballa.

This new tuning kit for the Porsche 991 Carrera is not one of the eccentric packages we often see from renowned tuners, most probably this is why it received a quite positive feedback from the enthusiasts.
