Description
The 3R‑2 is a welded steel sim racing chassis built for drivers who want real rigidity, real tactile clarity, and real fabrication‑grade engineering. Made from heavy wall HSS steel and CNC cut components, the 3R‑2 delivers the strength and stability that aluminum profile rigs simply can’t match.
At the core of the system is a unified welded arch that creates a direct, continuous load path from the wheel deck into the base frame. This eliminates the flex, joint movement, and vibration loss common in modular rigs. The result is Immersive Frame Resonance (IFR) — a high‑bandwidth tactile environment that preserves the full detail of your direct drive wheelbase, pedals, and haptic hardware.
The 3R‑2 uses friction‑drilled and form‑tapped (FDFT) structural threads, giving you deep, high‑strength mounting points with no through bolts, no T‑nuts, and no slip. Every adjustment locks into steel with repeatable precision.
A diamond rotated telescoping wheel arm provides 400 mm of smooth travel. The 45° rotated HSS profile self‑centers under load.
Ergonomics are fast and frustration‑free. With the REST system (Rapid Ergonomic State Transition), you can adjust your wheel, seat, and pedals in under two minutes. The wheel arm moves by hand; the seat and pedals adjust with a couple 13 mm wrenches. No disassembly, no guesswork. No wasted sessions.
At just 70 lbs, the 3R‑2 is also motion‑ready. Its low mass and high rigidity reduce actuator latency, making it ideal for high‑fidelity motion systems.
Every chassis is fully assembled, and QA‑checked before shipping. End‑user setup takes less than 15 minutes.
The 3R‑2 is built for long‑term stability, high‑torque wheelbases, and drivers who want a rig that behaves like real equipment — because it is.
