Based on the typical terminology used in the Street Legal Racing Redline (SLRR) modding community, "solid feature" is likely referring to a specific coding syntax or a modding concept: Solid Parts (versus Flexible parts).

Here is a breakdown of what the "solid feature" entails in SLRR V2.3.1 mods:

3. Part & Performance Mods

• Realistic Engine Swap Pack – Adds over 30 engines with proper torque curves.
• Widebody Kit Compilation – Uses the game’s existing weld/panel system.
• Forged Internals & Boost mod – Unlocks 40+ PSI without blowing the motor (for sandbox tuning).

1. The "Solid" Script Command

In the .rpk (resource pack) and .java scripts used to define car parts, there is a specific command often referenced by modders:

solid

What it does: This tag defines how a 3D part interacts with the game world.

• Solid Parts: These parts have physical collision. If you drive into a solid bumper, the car will stop or take damage. The game engine calculates physics collisions for these meshes.
• Non-Solid (Ghost) Parts: If a part is not flagged as solid (or is incorrectly scripted), the mesh will be visible, but you can drive right through it.

Why it is a "Solid Feature" (Pun Intended): In V2.3.1, stability is key. Poorly defined solid parts are a primary cause of game crashes. If a modder creates a complex body kit but forgets to assign the solid flag to the collision mesh, the part will look good but be useless in a crash. Conversely, if they assign complex collision meshes to every small detail, it can lag the game. High-quality mods balance this by using simplified "collision shapes" that are flagged as solid, while keeping visual details separate.
