German tuner wheelsandmore has unveiled an upgrade program for the Maserati GranTurismo. How do you make a quick car faster? Lighten the feet. And, that is what they've done adding lightweight forged wheels. Additionally, wheelsandmore offers a handmade stainless steel exhaust system with remote control flaps. This reduces backpressure and makes the car sing a sweet, seductive note. [Motoring Exposure]
