Moza R21 Ultra Compatibility

Moza R21 Ultra is a popular choice, but “compatible” should mean more than just bolt holes. Stable screens matter more than people expect. A solid cockpit and the right monitor stand help you keep a consistent eyepoint and FOV. This collection helps you match Moza R21 Ultra to a SIMGASM cockpit, with practical mounting suggestions and a clean upgrade path.

Recommended SIMGASM cockpit starting points

• Club (80×40) – a great all-round base for most wheelbases.
• Sport (120×40) – extra headroom for stronger direct drive and heavy braking.
• Pro (160×40) – maximum stiffness and adjustment for high-torque and motion-ready builds.

Mounting tips that make a real difference

• Pick the mount style first: front wheel mount, bottom wheel mount. A stiffer mount preserves detail and reduces unwanted vibration.
• Plan your pedal forces: load cell braking demands a stable pedal position and a seat that lets you brace comfortably.
• Keep your eyepoint consistent: pair your cockpit with a solid monitor stand so FOV stays repeatable.
• Leave room for add-ons: add a shifter and handbrake mount when you expand into rally, drift or endurance.
