FiveM Mechanic Script by JG | Dyno, Tuning, Stance

From scratch-made manual transmission swaps to fully-synced per-wheel stance adjustments, JG transforms the humble mechanic shop into the beating heart of your server’s car scene. Whether you run a low-rider crew, a JDM tuning collective, or a busy economy server with daily breakdowns, your mechanics finally get tools that justify the job — and your drivers get a culture worth obsessing over.

JG Mechanic Script is the FiveM mechanic script that turns vehicle ownership into a living, breathing part of your roleplay city — where tuning, stance, dyno runs, and servicing all matter. Every wrench-turn feels real because the script is built around actual mechanic workflows, not menus pretending to be one. This is the depth car-focused servers have been waiting on.

🚗 Advanced Vehicle Stance & Manual Transmissions

The features that turn your city into a genuine car culture destination — built so creative players can finally make builds they previously didn’t think were possible in FiveM:

• Manual transmission swaps — convert any vehicle’s automatic transmission to manual, adding genuine driving skill to everyday city traffic.
• Stance persistence — every adjustment is saved when storing or retrieving from a garage, so your build stays exactly as you left it.
• Per-wheel stance adjustment — suspension height, camber, and tracking on each wheel individually, fully server-synced for everyone to see.
• Transmission swaps via the tablet — performed using an item or society money. Excludes electric vehicles.
• Skill-rewarding consequences — once mastered, manuals squeeze extra performance from your engine; shift too late and you’ll damage it, sending you back to a mechanic sooner than expected.
• Stance via tuning menu or item — choose how you want to gate the feature on your server.

🔧 Tuning, Respray & Performance That Goes Beyond Stock GTA

Every tuning option you’d expect — and a lot more besides. From the latest Chop Shop DLC additions to engine swaps with streamed sounds, here’s what’s under the hood:

• Chameleon colours — unique chameleon paint that extends to wheels and interior where the vehicle supports it.
• Advanced respray — searchable base GTA colours with primary/secondary sync and a pearlescence toggle, plus full RGB selection for millions of unique combinations.
• NOS support — fully integrated into the mechanic install workflow and invoicing.
• Self-service or mechanic-applied tuning — players pay and apply themselves, or place an order for a mechanic to install. Disable any specific tuning option via the config.
• Full tuning suite — every possible option including all DLCs and the 7 new Chop Shop plate options, browsed through a sleek UI with automatic camera angles or free-cam preview.
• Custom performance options — define your own performance modifications via the config and choose exactly how they affect handling or vehicle sound.
• Performance tuning beyond stock GTA — pre-configured V12, V8, V6, and I4 engine swaps with custom streamed sounds, plus tyre, drivetrain, and brake upgrades.
• Granular pricing — price each category separately (performance, cosmetics, wheels, respray) with multipliers, or set prices proportional to vehicle value pulled from JG Dealerships, QBShared, or vehicles.meta for a fairer economy.

📊 The Mechanic Tablet, Dyno & Automated Invoicing

The tablet is the central tool that ties every mechanic interaction together — no more standing on markers to do real work:

• Built-in dyno — runs a 30-second performance test showing horsepower and torque as the engine progresses through its RPM range, with a final stats screen and shareable graph.
• Synced across the business — every employee of a mechanic business sees the same invoice list, so nothing falls through the cracks.
• Connect or manage — link a vehicle to the tablet to start work, or use it purely for business management without a vehicle attached.
• Editable, saveable, resendable — create invoices from scratch, edit any field, save them for later, and resend at any time.
• Mechanic tablet — configurable as a command or inventory item, lets mechanics roam the shop freely without marker dependency.
• Automatic invoicing — invoices generate themselves as the mechanic installs tunes, NOS, or completes services. Mechanics just enter prices and send.

🔍 Servicing, Repairs & The Mileage Economy

Vehicles wear, break, and need attention — and JG turns that reality into a recurring economy loop for your mechanic businesses:

• Vehicle cleaning — integrated into the mechanic workflow as an item-driven option.
• Flexible repair options — players self-repair at tuning locations, place a repair order, use a repair kit, or apply duct tape for a quick and dirty fix.
• Includes jg-vehiclemileage — the required mileage dependency is free and bundled with the script.
• Value-proportional repair pricing — keep your economy balanced by tying repair costs to vehicle worth.
• Mileage-based servicing — parts wear out over distance driven, requiring inspection and potential replacement at a mechanic to keep performance at full strength.

🛠️ A FiveM Mechanic Script Built for Modern RP Servers

Most mechanic scripts give you a menu, a marker, and a price list. JG gives you a workflow. Mechanics roam their shop with a tablet, connect to vehicles when ready, run a real dyno that takes time, and send invoices with itemised pricing. Drivers chase performance through engine swaps, transmission changes, and stance tweaks that survive garage saves. The result is a car culture your players actually engage with — not a chore screen they click through.

💡 LightingControl+, Car Lifts & Inventory Integration

The polish features that make your mechanic shops and late-night car meets genuinely unforgettable:

• Interactable car lift prop — a real, usable custom car lift prop you can place anywhere on the map, automatically job-locked to mechanic businesses.
• Item-driven functionality — tablet, tuning order installation, stancing, engine swaps, NOS, brakes, repairs, cleaning, lighting control, and servicing can all be tied to inventory items.
• JG LightingControl+ — an inventory item that toggles RGB xenons and underglow on or off, with effects like rainbow and flash for car meets that actually feel alive at night.

⚙️ Compatibility, Frameworks & What You Need to Run It

This FiveM mechanic script slots into modern roleplay stacks as a serious upgrade to the standard QBCore mechanic script setup, with flexible pricing integrations that pull vehicle values from JG Dealerships, QBShared, or vanilla vehicles.meta. The included jg-vehiclemileage dependency means the mileage-based servicing loop is ready to deploy out of the box, with no extra purchases required. All animations and effects are designed around OneSync Infinity so every player sees the same synced world — stance, lighting, and mechanic work included.

🪝 Sync, Performance & Discord Integration

The technical backbone that lets every feature scale without dragging your server down:

• Discord webhooks — up to 7 separate webhook URLs for granular logging and notifications across different channels or staff teams.
• No wasteful while loops — sync is handled through state bags rather than infinite polling, keeping resource use low even with many concurrent players.
• OneSync Infinity state bags — all effects and animations sync to nearby players for maximum shared immersion.
• 0.0–0.1ms resmon usage — extensively optimised for large-server performance, with heavier client effects (stancing, NOS, LightingControl+) only spinning up when actively in use.

❓ Frequently Asked Questions

Q: Do I need to buy any other resources to use the mileage-based servicing feature?

A: No — jg-vehiclemileage is the required dependency for servicing and it’s included free with this script. Drop it in alongside JG Mechanic and the servicing loop is ready to use.

Q: Can I disable specific tuning options or features I don’t want on my server?

A: Yes. The config lets you disable specific tuning options, and almost every piece of functionality — including the tablet, tuning order installation, stancing, engine swaps, NOS, brakes, repairs, cleaning, lighting control, and servicing — can be configured to use inventory items or be gated behind your own rules.

Q: How does pricing work, and can I tie it to vehicle value?

A: Pricing is highly configurable per category (performance, cosmetics, wheels, respray, repairs) with multipliers, and you can set prices proportional to a vehicle’s value fetched from JG Dealerships, QBShared, or vehicles.meta for a balanced server economy.

Q: Does the manual transmission feature work on every vehicle?

A: It works on any vehicle with an automatic transmission, except electric vehicles. Players perform the swap via the tablet using an item or society money, and inexperienced shifts will damage the engine — adding real consequence to careless driving.

Q: How performant is JG Mechanic on a busy server?

A: The script maintains 0.0–0.1ms resmon usage during normal operation, with heavier draws only on active client effects like stancing, NOS, or LightingControl+. Sync runs through OneSync Infinity state bags rather than infinite while loops, so resource use stays low even with many concurrent players.
