BEFORE YOU BUILD YOUR RIG

Which cockpit should I compare first?

Start with the FX1 if a Formula seating position is your priority. For GT-style setups, compare the Chassis 4.0 steel construction with the AX80 and AX160 aluminum profile platforms, then check mounting requirements and space.

Are seats and monitor stands included?

The FX1 includes its Formula-style seat. AX80 and AX160 seats are sold separately unless explicitly included in a bundle. For Chassis 4.0, check your selected configuration. Explore racing seats and monitor stands to complete your setup.

Will my wheelbase and pedals fit?

Match your exact hardware model to the product's compatibility list and selected wheel mount. Check pedal mounting and adjustment requirements too. If you need help, contact our team before ordering.

Does “available to order” mean immediate shipping?

No. Check the selected product and variant for stock, stock and shipping timing before checkout. Availability can vary between configurations.
