German tuner Wheelsandmore has a performance package for the Mercedes-Benz SL 65 AMG that is modest enough to sound like a reasonable option against the SL 65 AMG Black Series. For the power ugrade, Wheelsandmore does some ECU-remapping and adds a handmade exhaust system to bump the 6.0 liter twin-turbo V12 engine up to 697 PS (513 kW) and 1,150 Nm of torque from the production model's 612 PS (450 kW) and 1,000 Nm. The SL 65 AMG Black Series comes with 670 PS (493 kW) but with an electronically-limited torque of 1,000 Nm (a feature Wheelsandmore removes for its tuning of the standard SL 65 AMG).
Also on hand are, of course, Wheelsandmore's 3-piece forged rims (6Sportz) in 10 x 20-inch and 12 x 20-inch dimensions for the front and rear, respectively, wrapped in 255/30/20 (front) and 305/25/20 (back) Dunlop tires.
A suspension kit is also part of the package - Wheelsandmore´s "LowMaXX" electronic lowering module that maintains serial settings and raises the car at around the 72 km/h (45 mph) mark to provide a more comfortable ride.
