FiveM Lowrider Hydraulics System

I’m kicking off Phase 1 of a standalone lowrider hydraulics script for FiveM. The code must be written in Lua on the QBCore framework, kept lightweight and modular so it can slot straight into an existing server without touching handling editors, physics simulators, or heavy UI packages.

Here’s exactly what I need delivered in this first phase:

• Core hydraulics logic that lets me raise or lower the front, the entire rear, and each rear wheel independently
• Adjustable lift/drop speed values I can tweak in a single config file
• Hard limits on suspension height to avoid unrealistic travel
• Dual-input support: controller triggers/buttons and simple keyboard keybinds (no menu spam)
• A vehicle-filter check so only designated lowrider models react to the script
• Real-time hydraulic sound effects baked in (keep it lightweight—no huge audio libraries)
• A minimal preset system that lets players save a setup to disk and re-apply it in game with one key press

Keep the code readable, commented, and optimized; I intend to expand on it later, so a clean event structure and logical file layout are essential. No external dependencies beyond QBCore and the standard FiveM natives.

If everything meets the above spec, along with smooth in-game performance and no debug spam in the console, Phase 1 will be considered complete and we can talk about future enhancements.
