Rolls-Royce might think the Ghost II exits the factory in a state of perfection, but Sopfec has found room for improvement in both power and aerodynamics. Spofec's ECU remap unlocks 114 horsepower from the twin-turbo V12, for a total of 685. This drops the 0-60 time for the 5,700-pound land yacht to a scant 4.5 seconds. A new suspension control module drops ride height by 1.5 inches, getting the most out of the new, wind tunnel-sculpted carbon fiber aero pieces. Vossen collaborated on the new forged alloy twin-spoke wheels, and a new, flap-regulated multi-mode exhaust system adds a new aural note. Buyers can buy complete packages or pick their upgrades a la carte.
