ASR 3 vs ASR 4 [Flat Face] vs ASR Pro: Which Cockpit Fits Your Rig?

Picking the right aluminum profile cockpit comes down to how much torque your wheelbase makes and how stiff your brake pedal feels under your foot. Advanced SimRacing builds its frames in North America using thick-walled aluminum extrusion and laser-cut steel brackets.

Frame Thickness and Direct Drive Rigidity

The ASR 3 ($522.49 net with code SIMRACINGNATION5) uses a 3-inch by 1.5-inch open-slot aluminum base frame. For drivers running 8 Nm to 20 Nm direct drive wheelbases and stiff load-cell pedals, the ASR 3 stays rock-solid without taking up extra floor space.

Stepping up to the ASR 4 [Flat Face] ($807.49 net with code SIMRACINGNATION5) upgrades both the base rails and steering uprights to 4.5-inch by 1.5-inch smooth-sided extrusion. That extra wall height stops any steering column twist when you bolt on a 25 Nm wheelbase or add haptic motion actuators.

At the top of the GT lineup sits the ASR Pro ($1,092.49 net with code SIMRACINGNATION5). Built from massive 6-inch by 1.5-inch smooth flat-face profile, it includes quick-release adjustment levers on the wheel deck and pedal tray so multiple drivers can change positions in seconds.

Final Verdict: Which ASR Chassis Should You Buy?

• Best Mid-Range Value: Grab the ASR 3 ($522.49 net) if you run an 8 Nm to 20 Nm direct drive base in a compact room.
• Best All-Around Sweet Spot: Choose the ASR 4 [Flat Face] ($807.49 net) for 25+ Nm wheelbases, heavy hydraulic pedals, and motion systems.
• Best Multi-Driver Flagship: Upgrade to the ASR Pro ($1,092.49 net) for 6-inch profile stiffness and tool-free adjustment levers.
