Simucube 3 Pro review:
the same 25 Nm, a different wheelbase.

Review disclosure: Simucube supplied the Simucube 3 Pro for review and I retained it, and it has been the wheelbase in my rig for several months. I was not paid for this review, and Simucube did not see it before publication or have any approval over what it says. The Simucube links below go directly to the manufacturer and are not affiliate links — The SimRacing Den is not in a Simucube affiliate programme, so nothing you buy from Simucube through this review earns me anything. Other links on this page, to my discounts directory and rig builder, may. I ran a Simucube 2 Pro before this one and had both in the rig back to back, so the driving comparisons here come from using them, not from reading a spec sheet. Every Simucube specification, price and compatibility claim below is from Simucube’s own published material rather than my own testing.

The Simucube 2 Pro has been a reference point in high-end direct drive for years, and the obvious question about its replacement has a boring answer. Both wheelbases produce 25 Nm. If you are shopping on the torque figure, there is no upgrade here at all.

That is the wrong place to look. What Simucube changed is the sensor, the motor control, the quick release, the way the base talks to your PC, the way it bolts into your rig and the box you reach for when something goes wrong. Some of that improved my setup in ways I notice every session. Some of it added cost I would want a new buyer to see coming.

What actually changed

The Pro is the middle model in the Simucube 3 range. The Sport produces 15 Nm, the Pro 25 Nm and the Ultimate 35 Nm, and all three share the same 23-bit absolute angle sensor. Depth is the only external dimension that changes across the range.

Figures are from Simucube’s specification table and product page. The platform line is not a small print detail: Simucube’s FAQ answers the console question with a flat no, across the whole product line.

Simucube 3 Pro vs Simucube 2 Pro

The table is where this comparison really starts, because the differences that carry the price are structural; the sensory ones are real but small, and I come to those next. Two lines in it are worth pausing on, because I have seen both stated the other way round. The SC2 Pro mounts from the front only, on a 145 mm pattern — bottom mounting is an SC3 addition, not something the SC3 took away. And the SC3’s widely quoted 135 mm figure is the front pattern; the bottom T-nut pattern is 78.4 mm. If you are reusing a plate, check which of those two numbers you are actually measuring against.

The last line matters just as much. Tuner is not an SC3 exclusive. Simucube brought all Simucube 2 wheelbases into Tuner with version 2.5 in March 2025, and has said in plain terms that the SC2 continues to receive software updates, RMA handling and support. An SC2 owner who has not looked at current Tuner is comparing their old software against new hardware, which is not a fair comparison of the two bases.

The feedback, and why 25 Nm is headroom

Most of my time with it has gone into the Porsche 911 GT3 Cup 992.2 at Road America, which is a useful car to judge a wheelbase on because so much of what you need to know arrives late. It is rear-engined, the front goes light without warning you first, and there is constant engine vibration coming through the chassis that a lesser base smears across everything else. The SC3 Pro keeps those separate. I can feel the front start to give up without losing the texture underneath it.

Simucube’s marketing says the SC3 introduces new motors. Its own comparison table says something more useful, and more honest: the Sport and Pro carry the same proven SPM motor as the Simucube 2, and only the Ultimate gets a new one. What changed on the Pro is the control algorithm, which Simucube calibrates individually for each base instead of shipping as standard firmware, and which it credits for the quieter running. That is worth knowing before you read anyone’s impressions, mine included, because it sets a realistic ceiling on how different this can feel. I drove both bases but I measured neither, and I would be sceptical of anyone who tells you the jump from a 22-bit to a 23-bit sensor is something you can feel as such. It is a specification, not a sensation.

Having run them back to back, the difference in feel is real and it is subtle, and I want to be precise about both halves of that. It is not that information appears which was not there before — the SC2 Pro was never short of detail. What I noticed, once I was in cars I know well, is that the SC3 stays tidier when several things land at the same time: a kerb and a load change read as two events rather than one busy moment. I will stand behind that. I also would not have picked it blind in an unfamiliar car, and it is not on its own a reason to spend this much money.

Noise is the one difference that needed no concentration to notice. Back to back with the Simucube 2 Pro, the SC3 Pro is quieter, and after several months it is the quietest direct drive base I have run — quiet enough that it stopped being something I registered during a long stint.

The 25 Nm figure is headroom, not a setting. I run well under it, and I set force per car rather than globally, because a GR86 and a GT3 car have no business feeling the same. The reason to have the range is clipping: once the sim asks for more force than your configured output can represent, everything above that ceiling arrives at the same strength and you lose the distinction between a heavy load and a very heavy one. iRacing’s own guidance is to set strength so the force bar never fills under normal driving — kerbs and big bumps are fine — and it warns that its auto setting is often too strong on powerful direct drive wheels.

So the useful question is not whether 25 Nm is enough. It is whether you have set the base up so the top of its range is doing something for you. A powerful wheelbase configured badly is just a heavy one.

One safety point that belongs here rather than in a footnote: Simucube instructs you to test the torque-off button before every session. On a base that can deliver this much torque, that is an instruction, not a suggestion.

Telemetry effects and Tuner

The SC3 can generate effects from sim telemetry rather than from the force feedback signal alone: road texture, ABS, cornering and engine RPM. These are additions, not upgrades to the steering feel, and I treat them that way.

My test for each one is whether it tells me something. ABS is a good example of an effect earning its place, because it reports a condition I would otherwise have to infer. Engine RPM I keep subtle, partly because my rig already has motion and belt tension doing related work and I would rather those systems each have a job than all shout the same thing at me — I go into how I split those duties in my Qubic QS-210 versus D-BOX G3 comparison. If an effect only makes the wheel busier, I turn it down or off.

Tuner itself is the reason a base like this is livable. Save a baseline you like, then change one thing at a time and drive it. Change damping, friction, strength and three telemetry effects in one sitting and you will end up with a profile that feels different without knowing which change helped. That is how I have talked myself into believing hardware was the problem before.

The Link Quick Release and your existing wheels

The quick release is the change you feel every time you use the rig rather than once at installation. With a Link-compatible wheel, LightBridge carries power and data across the connection, so the wheel goes on and it works — no cable to thread, nothing to unplug before it comes off.

I have run the SC3 both ways — with a Link wheel, and with USB wheels attached through the Link quick release as a purely mechanical connection — and the gap between them in daily use is wider than it looks written down. With the Link wheel a change takes seconds, with nothing to plug in and no battery to charge. With a USB wheel you are back to threading a cable, which is fine, but it is the same experience you already had, on a quick release you paid a premium for. That contrast is both the clearest argument for the Link platform and the clearest argument about what it currently costs you.

Here is the part that gets misread, and it is the single most important compatibility fact in this review. Fitting a Link Quick Release to an existing USB wheel does not make that wheel cable-free. Simucube is explicit that the Link QR can be used purely as a mechanical attachment regardless of whether the wheel supports the electronics — and for those wheels the cable tucks into a cavity in the quick release and still runs to your PC. Simucube’s FAQ says the same thing from the other direction: USB wheels fitted with a Link QR should be connected directly to the PC for data.

It gets one level more specific than that, too. Some Link-compatible wheels take power through the quick release but still move data over Bluetooth — and mine is one of them. My Link wheel is a Simucube Savu Pro, and Simucube’s own specification for it reads: power transfer through the Link Quick Release, data transfer as a Simucube wireless wheel via the Link Hub. Living with it that is excellent — no cable, nothing to charge — but it is not LightBridge carrying the data, which is what the Delta Pro SC and the P1Sim Beau Rivage do. So “compatible” is not one answer — it is three separate questions about mounting, power and data, and the answer can differ for every wheel on your shelf.

My advice is to check each wheel individually before you order anything: will it attach, how will it be powered, and how will its buttons, paddles and display talk to the PC. And do not buy on the assumption that a future adapter or firmware update will resolve a compatibility gap later.

Adapters do cover more ground than people expect, in both directions. There is an adapter that brings the Link QR’s mechanical interface to a Simucube 2 base — mechanical only, with no wireless power or data. Going the other way, an adapter lets an SC3 take SQR wheels, which means an existing wheel collection does not have to be replaced, at the cost of giving up LightBridge in that configuration. If your reason for upgrading is the quick release alone, price both adapters before you price a wheelbase.

The Link ecosystem is small right now

This is my biggest reservation about the SC3.

Simucube’s own buyer’s guide currently names three Link wheels: the BavarianSimTec Delta Pro SC, Simucube’s Savu Pro and the SimuCore SSL-1. P1Sim sells a Link version of its Beau Rivage that the guide does not name. The brands listed as arriving — Ascher Racing, GSI, Cube Controls, SimRacingBay — are all marked 2026, which is another way of saying not yet — Simucube’s own comparison table dates native Link wheels to 2026 in the same breath. Three of those brands already sell wireless or USB wheels that work on the SC3 today, just not through LightBridge. So the wheels that can use the headline feature of this wheelbase are, today, a short list dominated by Simucube and its closest partners. Simucube publishes that guide itself, and it is the nearest thing to a compatibility list that exists.

That list is not entirely Simucube’s to define, though. Heusinkveld introduced the One SC this month, a wheel built specifically for Simucube 3, though neither company has called it a Link wheel — 1,060 grams including its integrated hub, with the 4.3-inch Simucube touchscreen and an 11-LED RPM bar configured in Tuner — and it appears nowhere on Simucube’s guide, not even among the 2026 names. I went through the specification in my Heusinkveld One SC news story. A brand of that standing building for the platform is the best argument that this situation improves. It also has no price and no release date, just a notify-me form, which is the best argument that it has not improved yet.

Your existing wheels are not locked out, but they do not become part of it either. Simucube Wireless Wheels run on the SC3 through the Link Hub and stay on their own batteries unless they are fitted with a quick release that supports power transfer. Bolting a Link Quick Release onto a wheel does not promote it into the ecosystem, and I want to be clear about that, because the marketing around this muddles it constantly.

I would much rather have had passthrough for every wheel. Choosing a closed connection instead struck me as a strange call when the wheel list was always going to start this short.

It is telling that Heusinkveld built the escape hatch itself. Heusinkveld fitted the One SC with an internal USB connector, which its own page describes as an alternative connection route for simracers with other wheelbases. The wheel is allowed to leave the ecosystem, even though the base will not let other wheels properly into it.

I do understand the reasoning, though. LightBridge sends data optically and power inductively across a gap with no contacts to wear out — a deliberately different and much narrower channel than a USB cable, not something you bolt USB onto afterwards. Simucube’s own framing is about consolidation rather than speed — one hub, fewer USB connections, what it calls a cleaner setup without USB clutter — which is the same argument behind routing everything through the Link Hub. As engineering it is coherent, and it is a bet on where their platform ends up in a few years rather than on where it is now.

As an owner, it still means a wheel I already like will never become a Link wheel, and the set that can is small and mostly theirs. Whether that matters comes down to one question: is the wheel you want on that short list? If it is, this is a better system than a cable. If it is not, you are buying a quick release you will use as a mechanical mount, and the feature you paid part of the premium for is a promise about 2026.

The Link Hub is required — and sold separately

The SC2 connected over USB. The SC3 does not. Simucube’s documentation is blunt about it: the wheelbase cannot be connected directly to a PC, and the Link Hub is required for inputs to register. The Hub is listed under required items and sold separately.

In my rig that was not an extra purchase, because I already run Simucube ActivePedals through Link — and that is the case where the SC3 is at its easiest to justify. You do not need a Hub per device; several Simucube devices share one, with an Ethernet switch when you need more ports than the Hub has. If you are weighing the pedals as part of the same decision, my ActivePedal Pro vs Ultimate comparison covers that side of the platform.

For a first Simucube purchase it is a different story, and it is the number most likely to catch someone out. Budget the Hub with the base, not after it.

The Control Box

The SC2 gave you a torque-off button. The Control Box still does that job, and it is the reason the box exists, but it adds a main power switch, wake-from-idle and a rotary encoder you can assign to parameters like force strength — adjustable from the seat, mid-session, without reaching for a mouse.

It is included in the box, and it is not optional in a second sense: the SC3 will not power on unless the Control Box is connected.

Mount it where you can hit it without looking.

Mounting: the numbers that matter

Front mounting uses the four threaded M8 holes on a 135 mm pattern, with screw length chosen for your plate thickness. Bottom mounting uses four T-slot nuts on the base at 78.4 mm with the supplied M6 screws. Simucube requires all four points either way, so a three-bolt improvisation is not a shortcut you get to take.

Bolt pattern is the easy part of this. The harder question is where the wheel ends up. The SC3 Pro is 303 mm long including the quick release against the SC2 Pro’s 270 mm. Simucube does not publish how that extra 33 mm splits either side of the mounting face, so I would not assume your wheel lands where the old one did — measure it against your seating position and monitor clearance before you commit to either.

What it actually costs

Simucube lists the SC3 Pro at US$1,599 to US$1,699 as I write this, and the spread is the point: the lower figure is the base without the Link Hub, the higher one with it. If you are new to Simucube, the top of that range is your price. The SC2 Pro is listed at US$1,299.

That is still not the number to compare. The honest comparison is the whole installation: base, Hub if you need one, wheel-side quick release hardware, any adapter, a mounting plate, and whatever you actually recover from selling what you are replacing. I would work that figure out before deciding the gap between the two bases is small.

Should you upgrade from a Simucube 2 Pro?

I have made this swap, though not on the terms you would: Simucube supplied the SC3 Pro, so I never had to weigh it against the money. Here is how I would weigh it if I had. If you own an SC2 Pro and you are happy with it, my answer is no — and I would not treat that as a criticism of the SC3. You are not moving from 10 Nm to 25 Nm. You are moving from an excellent 25 Nm wheelbase to a newer, better-integrated 25 Nm wheelbase, and the difference lives in the ecosystem rather than in the steering.

Before spending anything, I would do three cheaper things first: get onto current Tuner, spend real time on the profile rather than assuming the hardware is the limit, and price the quick-release adapter if the QR is what you actually want.

The upgrade starts making sense when several of the reasons stack up at once — you want Link wheels, you already run other Link devices, you need bottom mounting for a cockpit that will not take a front plate, you want the telemetry effects and the Control Box. One of those on its own is not enough. Four of them is a different conversation.

The test I would apply is whether you can finish this sentence with something specific: “the upgrade is worth it because it lets me…”. If the honest ending is “have the newer one”, keep the SC2.

For a first premium Simucube, it is much simpler. I would buy the SC3 Pro unless the SC2 Pro is discounted enough to matter, because you are buying into the platform Simucube is currently developing rather than the previous one, and you are planning your wheels and mounting around current hardware instead of around a generation you will want to move off. I would not stretch for it at the expense of a decent seat, a rigid cockpit and pedals you like — a 25 Nm base bolted to a flexing rig is a waste of both.

If you are shopping across brands rather than within Simucube, the comparison is wider than this review. My Simagic Alpha EVO Pro review covers another base in this class, and it is worth reading alongside this one before you commit at this price.

My final verdict

The Simucube 3 Pro is a good wheelbase that is easy to sell badly. Lead with the torque figure and there is no story, because the number did not move. Judge it on how it fits a rig and it makes much more sense: the feedback is clean and controllable, the adjustment range is deep without being a maze, the quick release improves day-to-day use, and the Control Box solves a real problem about reaching controls from the seat.

On reliability I can only report what I have. In several months of regular use it has not failed, dropped out or needed firmware rolled back, and I have never had to contact Simucube about it. That is one unit over several months rather than a fleet over years, so read it as an absence of problems rather than proof of longevity — but it is worth saying plainly, because a review that simply never mentions reliability is not the same as one that has nothing to report.

The costs are just as concrete. The Link Hub is required and sold separately. Your existing USB wheels will keep their cables. Mounting is more flexible but not a drop-in swap. And the ecosystem that justifies the new quick release is still small and still mostly Simucube’s.

For a new high-end sim racing setup, it is the one I would buy. For a working Simucube 2 Pro, my answer is no unless several of those reasons stack up at once.

One last thing, because it is the most useful thing I can tell you. The Simucube 3 Pro is my base of choice. It is what is bolted to my rig and what I choose to drive on. That is a preference rather than an argument, and I would still rather you bought this base for a reason you can name than because I happen to like mine.
