SPOFEC OVERDOSE for Rolls-Royce Cullinan Series II
SPOFEC introduces exclusive customisation for the Rolls-Royce Cullinan Series II, led by the striking OVERDOSE widebody kit in visual carbon, 24-inch high-tech wheels and a performance upgrade for the twin-turbo V12. The German refinement specialist focuses solely on Rolls-Royce vehicles and presents a sophisticated range that gives the luxury SUV a sportier, more distinctive character while preserving its hallmark elegance.
The sweeping OVERDOSE wing extensions add 12 centimetres to the Cullinan Series II compared with the production model and create space for bespoke 24-inch SPOFEC wheels developed with American premium manufacturer Vossen. A dedicated suspension kit lowers the ride height by about 35 millimetres to complement these king-sized rims, enhancing stance and road presence for the Rolls-Royce Cullinan.
SPOFEC boosts the twin-turbocharged 6.7-litre V12 to 520 kW (707 hp) and 1,060 Nm in the top-tier Black Badge version shown. The luxury SUV sprints from rest to 100 km/h in just 4.6 seconds, while an electronic limiter caps top speed at 250 km/h due to the vehicle’s considerable mass. SPOFEC stainless steel sports exhaust systems, available with or without electronic sound management, enrich the 12-cylinder’s voice; the version with actively controlled butterfly valves lets the driver switch between a discreet tone and a powerful soundtrack via remote control from the cockpit.
The OVERDOSE design underscores sportiness with tasteful precision. SPOFEC manufactures all aerodynamic enhancements in OEM-quality PU-RIM and carbon fibre for a precise fit and immaculate surfaces. A new SPOFEC front fascia with integrated LED position markers replaces the standard bumper and, together with surrounds for the side air intakes in visual carbon, gives the British SUV an even more distinctive face suited to high-end luxury SUV tuning.
The dramatic fender flares widen the refined Cullinan to 212 centimetres and flow into rocker panels that align perfectly with the broader arches. This treatment visually lowers and streamlines the five-door model for a sleeker appearance. Matching SPOFEC SP4 wheels measure 10Jx24 and wear high-performance tyres sized 295/30 R24 front and rear. Vossen produces the delicate, spatially offset spoke design and the hub cover that conceals the wheel bolts using advanced forging and CNC machining. Customers can choose from 48 colours with brushed or polished finishes to tailor the forged wheels to their Cullinan Series II.
SPOFEC calibrates the suspension kit specifically for the 24-inch tyres used with the OVERDOSE widebody. Lowering the ride height by about 35 millimetres reduces the centre of gravity and makes handling feel more dynamic and secure without compromising the Rolls-Royce emphasis on comfort. At the rear, a subtle spoiler beneath the back window and a diffuser fashioned in visual carbon complete the athletic look, while SPOFEC tailpipe tips integrated to either side of the diffuser provide a cohesive, performance-focused finish.
The performance upgrade relies on the plug-and-play SPOFEC N-TRONIC module, which introduces bespoke maps for injection and ignition alongside a moderate increase in boost pressure within the engine management. Output rises by 86.1 kW (107 hp) and torque by 160 Nm, delivering the headline figures of 520 kW (707 hp) and 1,060 Nm. This carefully engineered approach ensures strong, seamless power delivery that suits the character of a Rolls-Royce Black Badge Cullinan Series II.
Beyond the bodywork, chassis and powertrain, SPOFEC realises individual interior requests for any Rolls-Royce owner. The company crafts bespoke upholstery, trims and details to create personalised cabins that align with each client’s taste and the elevated standards of Rolls-Royce customisation.
