The Rolls Royce Cullinan is already the definitive luxury SUV, yet NOVITEC Spofec has pushed its design and performance envelope further with two distinct widebody packages. The Spofec Overdose Widebody Kit and the Spofec Overdose S Widebody Kit bring a commanding stance and enhanced aerodynamics to the Cullinan Series I and Black Badge Series I (2018–2024).
Each package is constructed from high-grade Polyurethane RIM, chosen for its ability to combine flexibility and durability with the precise fit required for a Rolls Royce. This ensures that even as the Cullinan’s lines are reshaped into something more muscular, the integrity of the vehicle’s luxury aesthetic is preserved.
The standard Spofec Overdose Widebody Kit lays the foundation for a bolder, more aggressive Rolls Royce Cullinan. Its design centers on expanding the SUV’s proportions while keeping a clean, flowing aesthetic.
Included in the kit are:
A new front bumper is designed for a broader, more aggressive look.
A rear diffuser that integrates seamlessly with the widened stance.
An 8-piece widebody set that extends the vehicle’s arches and side profile.
Side panels that tie the widened arches into the Cullinan’s bodywork.
Complete fixing material for precise and secure installation.
For those seeking an additional layer of style and performance, a rear spoiler lip is available to complement the package, further enhancing the aerodynamic profile. This kit is designed for owners who want to redefine the Cullinan’s road presence with a strong yet sophisticated transformation that holds true to Rolls Royce refinement.
Building on the Overdose foundation, the Spofec Overdose S Widebody Kit introduces added details and functional upgrades that push the Rolls Royce Cullinan into a new territory of exclusivity.
What sets the Overdose S apart is its expanded kit contents:
A redesigned front bumper that integrates LED lighting for a sharper, modern look.
A rear diffuser paired with custom exhaust tips gives the Cullinan’s rear profile a more performance-driven edge.
The same 8-piece widebody set as the standard Overdose kit, ensuring widened arches and bold stance.
Side panels that complete the widened bodywork.
All required fixing materials for installation.
An optional rear spoiler lip that mirrors the availability in the standard kit.
The addition of LEDs and exhaust tips makes the Overdose S package more dynamic both visually and functionally. These details highlight the difference between the two kits: while the standard Overdose offers an aggressive yet elegant update, the Overdose S adds features that emphasize a more performance-oriented and distinctive character.
Both the Overdose and Overdose S kits transform the Cullinan, but the differences come down to detail and expression:
Overdose Kit: Focused on clean widebody styling, larger proportions, and enhanced aerodynamics without altering the essence of the Cullinan too far. Ideal for owners who want presence without additional performance-inspired touches.
Overdose S Kit: Adds front bumper LEDs and exhaust-integrated diffuser, creating a sharper look with a more technical feel. Perfect for those who want their Cullinan to not only look wider but also carry functional, modernized elements.
Both options maintain the Rolls Royce Cullinan signature elegance, but the S kit stands out for those seeking a more dramatic transformation.
NOVITEC’s Spofec division brings the same engineering mindset applied to Ferrari, Maserati, Lamborghini, and McLaren to the Rolls Royce brand. By focusing on aerodynamics, fitment precision, and design harmony, Spofec ensures that every piece is as functional as it is aesthetic. Both Overdose packages reinforce this vision, blending bold styling with the Cullinan’s inherent luxury DNA.
