If you own a Maserati Quattroporte and are looking for improvements, then turn to the German Maserati tuning company MR Car Design for their latest package. It includes both performance upgrades and a new set of wheels to give your Maserati a unique look and feel. The tuners were able to customize the Maserati 4.2-liter V8 engine software and added a new exhaust system as well. The result is a power increase of 30 horsepower along with 29 extra Nm of torque, bringing the total output to 430 HP and 480 Nm of torque. The only cosmetic modification to the Maserati Quattroporte is the new 22-inch Vossen alloy rims wrapped in high performance tires measuring 245/30R22 up front, and 295/25R22 at the rear. Finally, a set of H&R springs, new 15 mm spacers for the rear, tinted windows all around, and custom tail pipe designs round out the Maserati Quattroporte kit.
