KCD Illegal Tuning | Advanced Vehicle Upgrades for ESX
Bring underground vehicle tuning to your FiveM server with item-based installations, persistent upgrades and configurable vehicle modes. Built for ESX Legacy, KCD Illegal Tuning combines performance upgrades with a blue, pink and white KCD interface.
Performance & Handling
- Three engine upgrade stages: 10%, 25% and 50%.
- Additional acceleration boost and stronger turbo brakes.
- Adjustable front/rear camber and wheel offsets.
- Switchable drift and cornering modes.
- Grounding upgrade with additional vehicle mass and grip.
- Burnout mode, Launch Control and a faster race gearbox.
- Switchable all-wheel drive and rear-wheel drive.
- Nitro system with refill bottles, configurable capacity, duration and cooldown.
- Anti-Lag with turbo-pressure retention and nearby exhaust effects.
Exhaust Customization
Switch between stock and configured racing audio profiles with the valved exhaust. Install continuous exhaust flames and choose their colour using a HEX input.
Installation & Persistence
Mechanics install upgrades using inventory items, a repair animation and a progress display. Configure authorized jobs, minimum grades and installation times.
Upgrades, switch states, flame colours and nitro fuel save automatically using the vehicle’s plate and model. A reusable reset tool removes this resource’s upgrades while preserving ordinary GTA modifications.
Flexible Integrations
- ox_inventory or native ESX inventory.
- Configurable notification and progress providers, including ESX, ox_lib, okokNotify and supported mythic_notify APIs.
- ox_lib and QB radial adapters, plus exports for custom menus.
- Commands for every vehicle action.
- German and English interface text and documentation.
- Configurable controls, upgrade values, permissions and feature availability.
Requirements
ESX Legacy, ox_lib, oxmysql, OneSync and a configured database. Selected third-party inventory, notification, progress or radial resources must be installed separately. QB radial integration requires a menu installation compatible with your ESX server.
Please note: Vehicle behaviour and flame appearance depend on the vehicle model and handling. The valved exhaust switches audio profiles; a custom engine soundbank or guaranteed volume increase is not included.
