The ASR 4 [Open Face] is a high-end sim racing powerhouse designed for those who demand absolute structural integrity and maximum utility. Featuring a massive 4.5" aluminum profile base and a reinforced steering column, this chassis is engineered to handle the highest torque direct drive wheelbases on the market with zero flex. Whether you are a competitive esports driver or a hobbyist seeking the ultimate immersion, the ASR 4 provides a rock-solid foundation that translates every detail of force feedback directly to the cockpit.
Why Choose the "Open Face" Model?
While the ASR 4 is available in our signature "Flat Face" style, the Open Face model is the preferred choice for the dedicated tinkerer and the utility-focused racer.
-
Maximum Versatility: The classic "Open Face" profile features exposed T-slots on all sides of the aluminum extrusions. This allows you to mount accessories—like shifters, handbrakes, keyboard trays, or DIY custom brackets—at any point along the beam without being restricted by a smooth surface.
-
Easier Adjustments: Because the T-slots are fully accessible, adding or repositioning hardware is often faster, as you have more "real estate" to work with when sliding in T-nuts and securing brackets.
-
Industrial Aesthetic: For many racers, the Open Face look represents the "classic" sim racing rig—a rugged, modular, and professional-grade machine that looks as serious as it performs.
Generation 2 Improvements
The ASR 4 has been completely overhauled using key learnings from our flagship ASR PRO:
-
Overhauled Assembly: Designed for a faster build with fewer parts, while significantly increasing overall stability and rigidity.
-
Gen 2 Pedal Tray & Heel Rest: A brand-new aluminum design offering industry-leading compatibility and effortless adjustability for height, angle, and position.
-
Flexible Wheel Deck: A redesigned deck that offers expanded range for your wheelbase position, ensuring a perfect ergonomic fit.
-
Pro Wheel Deck Option: You can now upgrade to the Pro Wheel Deck, which utilizes linear guide tracks and bearings for the most precise wheel adjustments in the industry.
