Racing Dynamics is one of the coolest BMW tuners, not only because of their huge obsession with horsepower, but also because of the amazing bodykits which are like their signature. They are currently working on some packages for the all-new BMW 5-series, and based on the emerged details, they are good! as always.
What Racing Dynamics is going to do is quite amazing! They are going to release a powerful version of the 550i so you don’t have to wait for the actual M5 to arrive. The 407hp turbocharged V8 of the 550i will undergo a surgery to give 620 hp! That’s more than the 2011 M5, for sure! Other modifications to this car include a new rear-locking differential, sport suspension and high performance braking system.
They also have a package for the 535i six-cylinder model in which the power is upped from the standard 306hp to 410hp. This car too will get new exhausts, suspension and brakes and will be a serous performer. It’s all very good, but we can’t wait to see what they have in mind for the body! We just hope that the 5er get RD’s superb front bumper!
