Kartik Mechanic System | The Most Advanced Mechanic System for FiveM 
The Kartik Mechanic System is a fully immersive and realistic mechanic experience for FiveM servers.
Built from the ground up after months of development, this system transforms the mechanic job into a deep profession with real maintenance, diagnostics, tuning, and shop management.
From realistic part wear to dyno testing, manual transmission, shop management, and advanced vehicle electronics, this script introduces a level of realism rarely seen in FiveM.

Core Features
Full Vehicle Customs Menu
A complete mechanic customization system including:
• Performance upgrades (engine, transmission, brakes, suspension, turbo)
• Cosmetic modifications (spoilers, bumpers, liveries, etc.)
• Full respray system with color picker
• Wheel customization
• Realistic part requirement system for every modification
Realistic Vehicle Wear & Maintenance
Vehicles track wear across 15+ individual mechanical components
Components include
• Spark Plugs
• Engine Oil
• Oil Filter
• Air Filter
• Tires
• Brakes
• Suspension
• Clutch
• Gearbox
• Pistons
• Radiator
• Fuel Pump
• Alternator
• Turbo
• Wheel Balancing
Each component degrades dynamically with driving distance and usage.
Realistic failure symptoms include
• Reduced braking power
• Steering vibration
• Engine smoke
• Suspension instability
• Alternator electrical failures
• Clutch slipping
• Gear grinding
• Tire blowouts
Repair & Replacement System
Mechanics can:
• Repair parts (restore partial condition)
• Replace parts (install brand new components)
Every repair action includes:
• Required items
• Repair animations
• Configurable duration
• Failure outcomes
Minigame System
A centralized minigame system powers all repair actions.
Dynamic Job Check
Mechanics working at registered shops can bypass or receive easier minigames.
Civilian Repairs
Non-mechanics can use repair kits but must complete a minigame.
Failure Consequences
Failed repairs can result in
• Vehicle damage
• Lost repair items
• Increased wear
Tiered Repair Kits
Multiple repair kits allow flexible repair systems.
Kit Types
• Standard Repair Kit
• Advanced Repair Kit
• Helicopter Repair Kit
Each kit can be configured to repair:
• Engine damage
• Body damage
• Mechanical wear
Vehicle class restrictions are fully configurable.
Cleaning & Wax System
Cleaning Kit
Vehicles can be washed using a sponge prop with realistic soap and water particle effects.
Wax System
Three wax tiers provide vehicle protection.
• Basic Wax
• Advanced Wax
• Premium Wax
Wax slows dirt accumulation and lasts for a configurable mileage distance.
Engine Stages
Upgradeable engine system with Stage 1–3 performance engines.
Mechanics obtain parts by opening engine boxes and crafting engines using materials like:
• Pistons
• Crankshafts
• Valves
• Turbo components
Higher engine stages provide more power but faster wear rates.
Turbo System
Four turbo stages:
• 27mm Street Turbo
• 34mm Turbo
• 41mm Turbo
• 52mm Racing Turbo
Turbos dynamically wear based on RPM usage and can fail when pushed beyond safe limits.
Anti-Lag System
Vehicles equipped with anti-lag produce realistic exhaust backfire pops at high RPM.
Fully configurable:
• RPM threshold
• Speed threshold
• Fire chance
• Cooldown
Nitro System
Optional nitro boost system allowing short bursts of extra power.
Fully configurable for:
• Boost strength
• Duration
• Recharge mechanics
Glowing Brake Discs
Brake discs glow dynamically when heated through aggressive braking.
• Heat builds during braking
• Heat dissipates over time
• Glow triggers after configurable thresholds
Manual Transmission System
A fully simulated gearbox system.
Features include:
• Manual shifting
• Clutch control
• Gear grinding
• Engine stalls
• RPM limiter warnings
• Gear sound profiles
Vehicles can support:
• Automatic
• Manual
• Semi-automatic
Transmission types can be switched dynamically.
Tuning Chip
In-vehicle tuning system allowing real-time adjustments.
Players can tune:
• Boost pressure
• Gear shift speed
• Rev limiter
• Traction control
Requires a tuning chip and tablet item.
Vehicle Electronics
Advanced vehicle stability systems.
Traction Control System (TCS)
• Detects wheel slip during acceleration
• Dynamically cuts engine power
Electronic Stability Control (ESC)
• Detects loss of control
• Applies braking to individual wheels
Both systems include:
• Toggle keybinds
• HUD indicators
• Vehicle class configuration
Vehicle Stancing
Mechanics can visually adjust:
• Suspension height
• Wheel camber
Includes a dedicated stancing bay interface.
Window Tint System
Vehicles support multiple tint levels depending on model compatibility.
Tint options are available inside the customization menu.
Car Lifts
Physical car lift props allow vehicles to be raised for underbody work.
Configurable options include:
• Lift speed
• Height limits
• Slow zones near limits
Dyno System
Fully functional performance dyno testing.
Features include:
• Real-time horsepower graphs
• Torque curves
• Interactive dyno rollers
• Integrated handling editor preview
Dyno rollers can be placed dynamically using the Object Gizmo system.
Mileage System
Vehicles track total distance driven.
Mileage data:
• Persists across restarts
• Can be used by other scripts
Developer export included:
GetMileage
Crafting System
Workbench-based crafting system.
Craft items including:
• Engine parts
• Mechanical components
• Misc mechanic items
