Why Structural Steel Frames Behave Differently Than Aluminum Extrusions (IFR Explained)

Understanding Immersive Frame Resonance in modern sim racing chassis When we began developing our HSS steel rig, we expected rigidity, strength, and predictable load paths. What we didn’t expect was how alive the frame would feel under force feedback. Steel doesn’t just hold the structure together — it carries the entire sensory footprint of the …

3R‑2 Technical Overview — Engineering Notes From Development

The 3R‑2 is the latest iteration of our welded‑steel sim racing chassis, built around one priority: structural certainty under real racing loads. Instead of relying on modular joints or friction‑based connections, the 3R‑2 uses a unified, triangulated steel structure to eliminate the micro‑flex that shows up when you push modern hardware to its limits. During …
