Simucube Rig Selection Without Compromise

A Simucube wheelbase should be mounted to a cockpit that matches both its torque and its mounting method. Simucube 2 wheelbases use front mounting, while Simucube 3 models support front or bottom mounting. Even with Simucube 3, a dedicated front mount remains the preferred solution for an uncompromising build because it secures the wheelbase directly between the cockpit uprights.

The required cockpit depends on the specific model. Simucube 2 ranges from 17 to 32 Nm, while Simucube 3 ranges from 15 to 35 Nm. A Sport model can work on a strong 40x80 cockpit, but the Pro and Ultimate versions justify substantially reinforced profiles.

This guide focuses only on SimXPro cockpits available with a proper front mount: GT-RS, XT120, XT160, GT-PRO, FR-DD and XFR.

FAQ

Why Use a Front Mount with Simucube?

A front mount supports the wheelbase directly from its mounting points instead of placing it on top of a wheel deck. This creates a clean installation, improves knee clearance and transfers steering loads directly into the cockpit uprights.

It is also necessary for Simucube 2, which uses front mounting only. Simucube 3 offers both front and bottom mounting, but front mounting remains the more appropriate choice for a high-end cockpit built around maximum rigidity.

Simucube Sport: GT-RS or XT120

Simucube 2 Sport produces 17 Nm, while Simucube 3 Sport produces 15 Nm.

The SimXPro GT-RS with the optional front mount is the minimum cockpit we would recommend for either Sport model. Its 40x80 profile construction is rated for wheelbases up to 20 Nm, leaving enough capacity for full-force operation.

Choose the SimXPro XT120 instead when you also use very stiff pedals, plan to add motion or simply want a heavier long-term platform. It uses 40x120 profiles, is rated up to 25 Nm and can be configured with a universal front mount.

Simucube Pro: XT120 as the Starting Point

Both Simucube 2 Pro and Simucube 3 Pro produce 25 Nm.

The XT120 is therefore the logical starting point. Its 25 Nm rating matches the Pro models, while the reinforced pedal deck and 40x120 structure create a stable foundation for high-end controls.

For additional structural headroom, choose either:

The SimXPro XT160, built from 40x160 profiles and rated for 30 Nm or more.
The SimXPro GT-PRO, also using a 40x160 structure, with an included front mount and a more refined closed-profile design.

The XT120 is sufficient. The XT160 and GT-PRO are better suited to users who deliberately want capacity beyond the current wheelbase.

Simucube Ultimate: XT160 or GT-PRO

Simucube 2 Ultimate produces 32 Nm, while Simucube 3 Ultimate is rated at 35 Nm.

At this level, the GT-RS and XT120 are no longer appropriate choices. The XT160 and GT-PRO are the relevant GT-style options because both use 40x160 profiles and are intended for wheelbases above 30 Nm.

Choose the XT160 for a traditional, highly modular aluminium-profile construction. Choose the GT-PRO when you want comparable structural capacity combined with smooth external profile surfaces and a more integrated visual design.

What If You Want a Formula Driving Position?

For a dedicated Formula setup, consider the SimXPro FR-DD or SimXPro XFR. Both product compatibility lists include Simucube 2 and Simucube 3 Sport, Pro and Ultimate models.

The FR-DD is the more straightforward dedicated Formula cockpit. The XFR is the more advanced choice, with greater adjustment intended to reproduce a precise single-seater driving position and a universal front-mount configuration.

For a Formula build without compromise, the XFR is the stronger recommendation. Choose the FR-DD when you want a dedicated Formula position without moving to the more elaborate XFR platform.

Conclusion

For Simucube Sport, the GT-RS with an optional front mount is sufficient, while the XT120 provides a heavier foundation.

For Simucube Pro, the XT120 should be treated as the minimum uncompromising option. The XT160 or GT-PRO provide additional headroom.

For Simucube Ultimate, choose the XT160 or GT-PRO. For a dedicated Formula seating position, choose the XFR, with the FR-DD as the simpler alternative.

Frequently Asked Questions

Can Simucube 2 be bottom-mounted?

No. Simucube 2 uses front mounting, while Simucube 3 supports front and bottom mounting.

Is the GT-RS enough for Simucube Pro?

No. The GT-RS is rated up to 20 Nm, while both Pro models produce 25 Nm.

Is the XT120 enough for Simucube Ultimate?

No. The XT120 is rated up to 25 Nm, below the 32 Nm and 35 Nm output of the Ultimate models.

Should I choose XT160 or GT-PRO?

Choose the XT160 for a traditional modular profile cockpit. Choose the GT-PRO for similar high-torque capacity with a smoother external design.

Build the Cockpit Around the Wheelbase

Match your Simucube to a front-mounted cockpit with enough structural capacity. Compare the GT-RS, XT120, XT160, GT-PRO, FR-DD and XFR before completing your Simucube setup.
