Interlock Ultra Bundle vs Separate Wheel and Base: Cost and Setup

Quick answer

The Interlock Base Module + Simucube 2 Pro Bundle is the simpler and often better-value route if you want a proven direct drive base and a GSI wheel that is designed to work together. Buying a wheel and base separately can make sense if you already own a compatible wheel or base, or if you want to mix brands for a specific reason. For most new direct drive buyers, the bundle removes compatibility guesswork and usually costs less than buying the same parts individually.

If you are moving to direct drive, one decision comes up quickly: should you buy a complete bundle or pick a wheel and base separately? The Interlock Base Module + Simucube 2 Pro Bundle is GSI's most straightforward way to start with Interlock, pairing the modular core with a GSI rim and the option to add paddle shifters, clutches, or the LED Matrix.

This comparison looks at what you actually get in that bundle, how it differs from sourcing a wheel and base on your own, and where each approach makes sense. We will use supplied catalog facts and avoid guessing about specifications that are not listed.

What the Interlock Base Module + Simucube 2 Pro Bundle includes

The bundle combines the Interlock Base Module with a GSI rim and a Simucube 2 Pro direct drive base. According to the catalog, the Interlock Base Module + Rim is the most straightforward way to start with Interlock, and you can add paddle shifters, clutches, or the LED Matrix as options. Available option types are Color, Configuration, and Interlock Base Module (Center Option).

The key point is that every piece is designed to work together, so your setup can grow over time. That modular path matters if you expect to change rims, add controls, or upgrade later without replacing the whole system.

• Check the Configuration and Center Option selections before ordering so the bundle matches your preferred control layout.
• Plan your add-ons early: paddle shifters, clutches, and the LED Matrix are separate choices, not automatic inclusions.

What buying a wheel and base separately involves

Buying separately means choosing a direct drive base and a wheel independently. You may already own a base, or you may find a wheel you prefer from a different brand. In that case, you need to confirm the mounting pattern, quick release compatibility, and electronics connection between the two parts.

The catalog does not list every mounting or electronics specification for these products, so we cannot claim universal compatibility. That is a real limitation: if you mix brands, verify the interface details with the manufacturer before buying. A bundle avoids that step because the parts are selected to work together.

• If you already own a Simucube 2 Pro, a standalone GSI wheel may be the cheaper path.
• If you already own a GSI rim, a standalone base may be all you need.

Cost comparison: bundle pricing versus separate purchases

The Interlock Base Module + Simucube 2 Pro Bundle is listed at USD 1485.57, with a catalog comparison price of USD 2153.00. That comparison price suggests the bundle is positioned as a saving versus buying the components at their separate listed prices, though actual separate pricing depends on the exact rim, base, and options you choose.

For context, other GSI wheel and Simucube 2 Pro bundles are listed at different price points: the X-29 bundle at USD 1339.80, the GT-MAX32 bundle at USD 2136.96, and the Hyper SL bundle at USD 2151.18. These are different wheels, so the price difference reflects the wheel tier, not just the base.

• Compare the bundle price against the sum of the exact parts you would buy separately, including any add-ons.
• Remember that option choices such as Color and Configuration can change the final price.

Setup effort and compatibility risk

A bundle reduces setup risk because the base, wheel, and module are intended to work as a system. You still need to mount the base to your rig and configure the wheel in your sim racing software, but you are less likely to discover a mismatch after the boxes arrive.

Buying separately adds research time. You need to confirm that the wheel's quick release and electronics match the base, and that the mounting pattern fits your rig. For some drivers that research is part of the hobby; for others it is a reason to choose a bundle.

• Budget an hour or two for firmware and software setup regardless of which route you choose.
• Keep the original packaging until you have confirmed everything works together.

Upgrade path and long-term flexibility

The Interlock system is described as modular, with the option to add paddle shifters, clutches, or the LED Matrix over time. That means the bundle is not a dead end: you can expand the wheel rather than replace it. This is a meaningful advantage if you like to change your setup as your driving evolves.

Buying separately can also be flexible, but only if the parts you choose are designed to be upgraded or swapped. If you mix brands, future upgrades may be limited by compatibility. The bundle keeps you inside one ecosystem, which simplifies later changes.

• If you plan to add controls later, confirm that the Interlock Base Module supports the add-ons you want.
• If you already own compatible gear, separate purchases may offer more immediate flexibility.

Trade-offs at a glance

• Bundle convenience: The Interlock Base Module + Simucube 2 Pro Bundle is designed as a system, so you spend less time checking compatibility between the wheel, base, and module. Choose the bundle if you want to minimize setup risk.
• Separate purchase flexibility: Buying a wheel and base separately lets you keep gear you already own or mix brands, but you must verify mounting and electronics compatibility yourself. Choose separate parts if you already own a compatible base or wheel.
• Cost: The Interlock bundle is listed at USD 1485.57 against a comparison price of USD 2153.00, while other GSI bundles range from USD 1339.80 to USD 2151.18 depending on the wheel. Compare the bundle price against the exact separate parts you would buy.
• Upgrade path: The Interlock system supports add-ons like paddle shifters, clutches, and the LED Matrix, so it can grow with you. If you plan to expand later, staying in one ecosystem is simpler.

Product facts

• Interlock Base Module + Simucube 2 Pro Bundle: The Interlock Base Module + Rim is the most straightforward way to start with Interlock. You'll get the modular core paired with a GSI rim, with the option to add paddle shifters, clutches, or the LED Matrix. Every piece is designed to work together, so your setup can grow over time. This is the bundle that reduces compatibility guesswork and gives you a clear upgrade path through Interlock add-ons.
• X-29 + Simucube 2 Pro Bundle: The GSI X-29 is our entry-level sim racing wheel that offers exceptional price to performance and is packed with features to take your sim racing experience to the next level. If the Interlock bundle is above your budget, the X-29 bundle is the lower-cost entry point into a GSI wheel with a Simucube 2 Pro base.
• GT-MAX32 + Simucube 2 Pro Bundle: The GT-MAX32 takes everything we've learned and elevates to a new level of technology including features, construction and assembly. A first for sim racing steering wheels, the GT-MAX32 is made from a continuous molded carbon footprint. This bundle is a step up in construction and materials, which matters if you want a more premium wheel than the Interlock or X-29 options.

Which should you choose?

Best for

• New direct drive buyers who want a proven base and wheel that work together out of the box.
• Drivers who want a modular wheel they can expand with paddle shifters, clutches, or the LED Matrix.
• Anyone who prefers to avoid compatibility research between a wheel and a base.

Not for

• Drivers who already own a compatible Simucube 2 Pro base and only need a wheel.
• Drivers who already own a GSI rim and only need a base.
• Buyers who specifically want to mix brands and are prepared to verify compatibility themselves.

For most new direct drive setups, the Interlock Base Module + Simucube 2 Pro Bundle is the lower-risk, simpler choice. If you already own one half of the equation, buying the other half separately can save money. Check the exact options and your existing gear before deciding.
