High-end wheelbases: Simucube, VRS, Asetek (15Nm+)
A real GT3 or prototype tops out around 10-12Nm of steering torque at the wheel on a flying lap (iRacing’s own per-car peak forces land in this range). Every base on this page — VRS at 15Nm, Asetek Forte at 18Nm, Simucube 3 Ultimate at 35Nm — already exceeds that. So the high-end question is not “do I need more force.” It is “what does the extra motor actually give me,” and the answer is detail and response speed, not strength.
What “high end” actually buys you
Section titled “What “high end” actually buys you”Past about 10-12Nm you stop buying steering torque you’ll ever use and start buying motor quality. A 20-30Nm motor isn’t the sweet spot because you need 30Nm. It’s the sweet spot because a bigger motor has a higher slew rate — it changes force faster and accelerates the rim faster — so kerb strikes, the front tires loading under braking, and the texture of a sliding rear arrive crisper and with less smoothing. That’s the upgrade you feel at this tier. Raw Nm is mostly headroom.
The three (four) brands
Section titled “The three (four) brands”Simucube
Section titled “Simucube”Simucube is the long-standing reference. The Simucube 3 Sport is 15Nm at $1,399, the Pro is 25Nm at $1,599, and the Ultimate is 35Nm at $3,299. SC3 orders opened in October 2025; Sport and Pro shipped that November, with the Ultimate following in 2026.
Two things to budget for. SC3 connects wheels through a separate Link Hub, an added cost on top of the base price. SC3 uses the new Link Quick Release, which mounts to nearly any 70mm-pattern wheel rather than locking you into one ecosystem; an adapter brings older Simucube 2 SQR wheels across mechanically too. The older Simucube 2 is still sold — Sport 17Nm, Pro 25Nm, Ultimate 32Nm — and remains an excellent base if you find one discounted.
VRS DirectForce Pro
Section titled “VRS DirectForce Pro”VRS is the value pick at this tier. The DFP15 is 15Nm at around $650-700; the DFP20 is 20Nm (small MiGE 130ST motor) at $799; the uDFP20 starts at 6Nm for ~$449 with software-upgradable torque all the way to 20Nm. The DFP15 needs no external control box, runs an all-aluminum chassis, and cools passively. VRS torque is famously raw and unfiltered, and it’s strongest paired with VRS’s own pedals and FFB profile. Spec for spec, you are paying roughly half what a comparable Simucube costs.
Asetek
Section titled “Asetek”Asetek runs a clean upgrade ladder on a shared 22-bit encoder: La Prima 12Nm (entry), Forte 18Nm, Invicta 27Nm. The Forte-to-Invicta step is a motor upgrade kit rather than a new base, so you can buy in lower and grow. Asetek discounts heavily — the summer sale runs up to 20% off — and its wheel and pedal ecosystem is strong, with Invicta as the flagship.
VNM is the enthusiast’s quiet favorite. Its telemetry-driven, iRacing-direct FFB plugin is widely considered ahead of the pack on fidelity, and the motors sit at or above Simucube on raw performance. On a community hardware ranking: Simucube, Asetek, and VNM are roughly equal on motor performance, a hair above VRS, then Conspit and Simagic below.
The honest diminishing-returns take
Section titled “The honest diminishing-returns take”The jump from a Logitech G29 to an 8Nm CSL DD is enormous. The jump from 8Nm to 20Nm is far smaller, and the data backs that up. The most-upvoted version of this debate is blunt: a racer went from 3k to 7k iRating after buying VRS pedals, then bought a Simucube Pro and gained exactly zero iRating. With real GT and prototype steering loads topping out around 10-12Nm, that range is the genuine sweet spot for feel, and everything above it is diminishing returns on lap time. Brake consistency from a proper load cell pedal set moves your results far more than another 10Nm at the rim.
Don’t forget the hidden costs
Section titled “Don’t forget the hidden costs”The base price is the start, not the total. An SC3 needs a Link Hub. Every base needs a quick release and a wheel rim, and the premium QRs and rims run hundreds on their own. Most important, a 20-35Nm motor will flex a flimsy desk mount or a soft rig until you can feel the wobble — a solid cockpit and stiff mounting are not optional at this tier. Budget the ecosystem, not just the box.
Who should buy what
Section titled “Who should buy what”- Most serious racers: a 15-20Nm base. VRS DFP15/DFP20 at ~$700-800 gives you 90% of the experience for half the money. Put the savings into pedals.
- Want the reference and the ecosystem: Simucube 3 Sport (15Nm) or Pro (25Nm). You’re paying for build quality, support, and the Link QR rim system.
- Want a clear upgrade path: Asetek — start at La Prima or Forte, kit up to Invicta later.
- Want the best FFB detail and don’t mind tinkering: VNM, especially if you race iRacing and value the telemetry plugin.

Frequently asked questions
Is a 20-35Nm base actually worth it over an 8Nm one?
For lap time, rarely. The jump from a Logitech G29 to an 8Nm CSL DD is enormous; the jump from 8Nm to 20Nm is far smaller. A real GT3 or prototype tops out around 10-12Nm of steering torque at the wheel, so that range is the genuine sweet spot for feel and everything above it is diminishing returns. Brake consistency from a proper load-cell pedal set moves your results far more than another 10Nm at the rim.
Is the Simucube 3 worth it / still the reference?
It is the long-standing reference for build quality and support, but past ~10-12Nm you stop buying usable steering torque and start buying slew rate and detail. The Sport is 15Nm, the Pro 25Nm, and the Ultimate 35Nm, and each connects wheels through a separate Link Hub that costs extra on top of the base price. SC3 also uses the new Link Quick Release, which mounts to nearly any 70mm-pattern wheel.
What is the best-value high-end wheelbase?
The VRS DirectForce Pro. The DFP15 is 15Nm at around $650-700 with no external control box, an all-aluminum chassis, and passive cooling; the DFP20 is 20Nm at $799. That is roughly half what a comparable Simucube costs, with famously raw, unfiltered torque that is strongest paired with VRS's own pedals and FFB profile.
What hidden costs come with a high-end base?
The box is not the total. An SC3 needs a Link Hub; every base needs a quick release and a wheel rim, and the premium versions run hundreds on their own. A 20-35Nm motor will also flex a flimsy desk mount or a soft rig, so a solid cockpit and stiff mounting are not optional at this tier.
