The Rolls-Royce Cullinan Series II is already one of the world’s most luxurious SUVs. Now, German tuning specialist SPOFEC has taken it even further with their new OVERDOSE widebody kit, making the Cullinan even more bold and powerful.
The OVERDOSE kit adds sweeping fender flares, making the Cullinan 12 centimeters wider than the standard model. This extra width allows for huge, custom-made 24-inch SPOFEC wheels, created together with American wheel maker Vossen. The SUV’s ride height can also be lowered by 35 millimeters with a special suspension kit, giving it a sportier stance.

SPOFEC boosts the Cullinan’s twin-turbo V12 engine to 707 horsepower and 1,060 Nm of torque in the top Black Badge model. This lets the big SUV sprint from 0 to 100 km/h in just 4.6 seconds. The top speed is still limited to 250 km/h because of the vehicle’s weight. SPOFEC also offers stainless steel exhaust systems, with or without electronic sound control, so owners can choose between a quiet or sporty exhaust note.
The exterior gets a new front fascia with LED position markers, carbon fiber air intake surrounds, and a rear spoiler and diffuser made from visual carbon. The wide fender flares and new rocker panels make the SUV look lower and more dynamic. The 24-inch SPOFEC SP4 wheels, made by Vossen, come in 48 colors and have a unique design that hides the wheel bolts.

Inside, SPOFEC can customize the interior to match any owner’s wishes, using the finest materials and craftsmanship.
The SPOFEC N-TRONIC module upgrades the engine by adjusting the fuel injection, ignition, and boost pressure, adding 107 hp and 160 Nm of torque. The result is a luxury SUV that not only looks more aggressive but also drives with more power and agility.

With the OVERDOSE widebody, SPOFEC shows how to give the Rolls-Royce Cullinan Series II a sportier, more unique look—while keeping all the luxury and comfort the brand is known for.
