Cutting up a Lamborghini Aventador, Serious All Black Cullinan, AMG GTS Wheels
A Lamborghini Aventador is about to get cut open with an angle grinder, and that’s the good part.
RDB LA’s latest shop vlog drops viewers into the middle of three builds running side by side on the shop floor: a rare Liberty Walk Limited Edition widebody kit going onto a Lamborghini Aventador, a brand-new Rolls-Royce Cullinan getting a full chrome-delete blackout, and an AMG GT S having its wheel fitment dialed in. The Aventador segment is the one that stops people mid-scroll — technicians slicing into factory fenders and quarter panels to make room for flares that are dramatically wider than anything Lamborghini ships from the factory.
- Technicians make the first cuts into the Aventador’s stock factory fenders and quarter panels to clear the Liberty Walk Limited Edition widebody flares — a Japanese aero kit rare enough that RDB LA frames this as a multi-episode build.
- A brand-new Rolls-Royce Cullinan gets a complete chrome-delete blackout package paired with a set of custom 24-inch gloss black aftermarket wheels.
- The Mercedes-AMG GT S gets its own segment in the episode, with the shop working through custom wheel fitment and tuning.
Cutting Into the Aventador
Liberty Walk kits aren’t bolt-on affairs. The widebody flares this Aventador is getting require the shop to physically remove sections of the car’s original fenders and quarter panels before any new panel work can go on — there’s no shortcut that preserves the factory sheet metal underneath a stance this aggressive. RDB LA treats the cutting stage as episode one of what they say will run two to three more installments before the car is finished, which is standard for a widebody conversion of this scale on a supercar chassis.
That’s the trade-off with a Limited Edition kit like this one: you’re not modifying the Aventador so much as rebuilding its silhouette from the door skins back. The flares are built to sit dramatically wider than stock, and getting there means the factory panels have to go.
The All-Black Cullinan Build
Where the Aventador segment is destructive by design, the Cullinan build is about erasing every trace of chrome. RDB LA takes a brand-new Rolls-Royce Cullinan through a complete blackout package — every piece of exterior brightwork that would normally flash in the sun gets deleted and replaced with gloss black, and the SUV is finished off with a set of custom 24-inch gloss black wheels.
An imposing, monolithic all-black aesthetic — no chrome, no brightwork, just a Cullinan that looks like it swallowed light instead of reflecting it.
The size of the Cullinan is what makes the treatment work. Rolls-Royce’s SUV is already the largest, most vertical thing in most driveways it parks in; strip the chrome and drop in matching 24s and the effect reads closer to a private security detail than a family hauler.
Dialing In the AMG GT S
The third build in the episode is quieter but no less deliberate. The Mercedes-AMG GT S comes through the shop for a set of customized performance wheels, with RDB LA working through fitment to get the stance right before the car goes back out. It’s the kind of upgrade — swapping in wheels built for the GT S’s proportions rather than generic aftermarket sizing — that changes how the car sits without touching a single body panel, a much smaller lift than what’s happening two bays over on the Aventador.
Multi-Episode Format
RDB LA’s channel has built its audience on exactly this format: showing the messy, unglamorous middle of a build rather than jumping straight to the reveal. The Aventador’s widebody conversion alone is set up to run across several follow-up episodes as the cut panels are replaced with the Liberty Walk flares and the car gets closer to its finished stance, giving regular viewers a reason to keep checking back on this specific car rather than just watching a single before-and-after.
By the time this Aventador rolls back out with its full Liberty Walk widebody in place, the Cullinan and its 24-inch blackout wheels will likely already be finished and gone — it’s the Aventador that’s going to need the patience, panel by panel, over the next few episodes.
