The Maserati GranTurismo is a sportscar you do not see that often in a tuningshop. Novitec Tridente decided to upgrade the GranTurismo S. They gave the engine a supercharger creating 600bhp. Together with an exhaust system, ECU upgrade, KW/Novitec Suspension, NM3 wheels (21 inch) and a full aero kit including a front lip, side panels, rear skirt and a rear wing should make your Maserati look different from the standard ones.
The aero kit is also completely available in carbon fibre to reduce the weight and increase the performance figures.
Thanks for the tip, Daveoflogic!
