Wheelsandmore press release :
German well known cartuner wheelsandmore revealed their custom modifications on the Aston Martin DB9 convertible.
The exterior received a special polyurethane bodykit, contending stylish sideskirts, aprons in the front as well as rear and a rear lid spoiler what gives the elegant britain a more aggressive look.
The stock version of the 6.0L V12 is coming with 476hp, too less for the tuning enthusiasts adding enormous 60hp and 50 lb-ft of torque with an ECU upgrade, special 200 cells sportcatalysts and a valve controlled, stainless steel exhaust system. Because of the remote controlled exhaust system the car now sounds like a V12 should sound, if the driver wants it.
