Esko Kustomz Builds 55 Cars for FiveM and Story Mode, Then Hands Modders the Toolbox Too

Anybody who has spent time on a FiveM roleplay server knows the cars make the city. A server can have great jobs and great scripts, but if the streets are full of stock game traffic, it feels like every other server. That is the gap Esko Kustomz fills: real-world cars built for GTA V, tested and packaged so they drop into a server or a single-player game without a weekend of troubleshooting.

The shop's site lists more than 55 vehicles, and every one ships two ways. There is a FiveM resource for servers running QBCore, ESX or vMenu, and there is a GTA V story mode version for players who never touch a server. Files unlock as soon as payment goes through.

What is on the lift

The current lineup leans hard into new luxury and performance metal. The latest drops include a 2027 Mercedes-Benz S-Class, a 2027 Mercedes-AMG, a 2027 Maybach S 680, a 2027 Audi RS5 and a 2027 Mercedes-Benz GLE Coupe, which comes as both a built version and a separate stock model. A 2026 Rolls-Royce Spectre and a Dodge Demon 170 round out the recent releases.

Then there is the car that tells you where the shop's head is at. The 2027 S-Class Floaters build puts a brand-new Benz on the kind of big wheels the donk and slab crowd would recognize, the same way real builders have been treating flagship sedans for decades. Sitting at the top of the site is a 1989 Chevrolet Caprice, a box Chevy, listed at no charge.

The catalog is split the way server owners actually shop. Lore-friendly cars, 16 of them, are built to fit a server's terms of service and the game's fictional world. Another 40 are non-lore, meaning real badges and real names. A $5 budget lane holds 16 cars, and three bundles package several builds together. Most individual cars on the front page run $10 to $20, with the GLE Coupe at the top at $60.

RevToolz: the shop's workbench, for sale

Converting a car between FiveM and story mode is tedious work. It usually means bouncing between OpenIV, CodeWalker and a pile of text files, fixing texture references, rewriting metadata and hoping nothing crashes on spawn. RevToolz is Esko Kustomz's answer: a desktop app that puts that whole workflow in one place. The current version is 3.25.94.

Conversion is the core of it. RevToolz offers a one-click installer for story mode vehicles, converts FiveM cars to single-player DLC one at a time or in batches, turns single-player DLC back into FiveM resources with a generated manifest, and packages a DLC file into a one-click OIV installer.

• Inspection: a 3D viewer for parts, paint, wheels and animations, an RPF explorer and a spawn viewer.
• Server performance: a poly size check, a poly optimizer that builds LODs and decimates models, a texture optimizer and a resource merger.
• Fixes: a crash fixer, an ID conflict fixer, a missing textures fixer, debadging, model unlocking and batch renaming.
• Tuning: a handling editor, a vehicle flags editor and an engine sound picker, plus tools for moving sounds between FiveM and story mode.
• Show and tell: photoreal renders and showcase videos from a built-in scene studio.

That middle group matters more than it sounds. A server packed with heavy custom cars can tank frame rates for every player in the city, and trimming polygons and texture weight is how server developers keep things smooth. RevToolz reports running anonymous totals on its page: about 267.9 million polygons cut, 10.6 GB of texture weight removed, 1,200 cars converted, 7,000 vehicles debadged and 19,700 jobs run, with a 98 percent success rate. Those figures come from the tool itself.

How it is sold

The basics are free with no key: the 3D viewer, the texture editor and the RPF explorer. A three-day trial opens every tool without a card. Paid plans are listed at $60 a year for Standard, which adds the conversion tools and a Discord bot that runs tools from a server, and $130 a year for Pro, which adds custom branding, sharing the bot with a server and monthly render credits. A five-seat Enterprise license is $500 one time. Render credits are sold separately, starting at 50 for $5.

RevToolz runs on Windows, macOS and Linux. On Windows, conversions run on your own machine. On Mac and Linux they run on the company's cloud engine, and the 3D viewer uses the cloud on every platform. Licenses lock to one PC, with a self-serve hardware reset every 30 days. It works with ESX, QBCore and standalone servers.

Why it matters to the car scene

Car games have become one of the biggest on-ramps into car culture. Plenty of people learned what a Maybach, a Demon or a box Chevy on big wheels looks like by driving one around Los Santos before they ever saw one in a parking lot. The modders who build those cars, and the tools that make the work less painful, are part of the scene now, the same way paint shops and wheel makers are on the street.

Esko Kustomz covers both ends of that. It builds the cars, and with RevToolz it sells the toolbox to everyone else building them. You can find the cars at eskokustomz.com and the toolkit at eskokustomz.com/revtoolz.
