The Simagic Alpha EVO Ultra 28 Nm is worth it if you want maximum torque headroom and already own, or plan to buy, a very stiff cockpit. It delivers up to 28 Nm with a 21 bit encoder and a low inertia motor, so you feel road texture, grip and weight transfer with a fast, direct response. For most drivers a 12 or 18 Nm base already feels strong. The Ultra pays off when you want detail without clipping at high force, and only on a Sport or Pro level rig.
Below you read what 28 Nm really means, who benefits and which SIMGASM cockpit keeps that power under control.
What does 28 Nm mean in practice?
Torque is the maximum twisting force the motor puts on your wheel.
You almost never drive at full torque. Most drivers set the overall strength far lower, so the wheel feels like a real car and not like a wrestling match. The value of a high torque base is headroom: big kerb strikes and crashes stay within the motor range, while the small details still come through at normal strength. That reduces clipping, the moment when the signal hits the limit and you lose detail. Our article on direct drive torque and how much cockpit you need explains this balance in more depth.
How does the Ultra compare with 9, 12 and 18 Nm?
All Alpha EVO bases at SIMGASM share the same 21 bit encoder, so the main difference is force and size.
The Sport 9 Nm and 12 Nm models measure 281 × 130 × 110 mm, the Pro 18 Nm grows to 317 × 130 × 110 mm and weighs 8,627 g without quick release. The Ultra sits above all of them with 28 Nm. For most GT, rally and road car drivers, 12 or 18 Nm covers everything. Read Alpha EVO 9, 12 or 18 Nm: which to buy if you are still between those three. The Ultra starts to make sense when you race heavy cars at high strength, drive with a large round rim or simply want the base you never outgrow.

Who really benefits from the Ultra?
Three types of drivers get the most out of this much torque.
Drivers who want zero clipping
If you like strong force feedback and still want every small bump, the extra headroom keeps the signal clean during big hits.
Drivers of heavy road cars and trucks
Big cars with a lot of self aligning torque feel more natural with force to spare, especially on a large rim.
Drivers building a final setup
If you plan a high end cockpit for years, the Ultra means you never need a stronger base later. Pair it with a quick release wheel from the Simagic range and you keep the same base when you swap rims.
Which cockpit handles 28 Nm?
A strong base on a weak frame feels worse than a smaller base on a stiff one.
At 28 Nm, every bit of flex in the wheel mount turns into vague, smeared feedback. The SIMGASM Alpha EVO Ultra 28 Nm compatibility list therefore includes only the Sport and Pro tiers. The Sport uses a 40 × 120 mm main profile and is built for serious direct drive and load cell builds, with clean cable routing and room for motion later. The Pro uses a 40 × 160 mm main profile with heavy duty steel reinforcement at critical mounting points, for maximum reserve under direct drive, braking and motion loads.

SIMGASM founder Johan Akkerman knows high torque rigs from the inside. Before SIMGASM, he helped test and develop the TRX chassis at Trak Racer, and his own setup moved to a Simucube 2 direct drive base. That experience shaped the stiff Sport and Pro frames, which SIMGASM has developed since January 2026 from its base in Wijk bij Duurstede. If you want the most headroom, choose a Pro sim racing cockpit. If you prefer a slightly smaller frame, the Sport is the minimum tier for this base.
Is the Ultra worth it for you?
Use these simple checks before you decide.
Yes, if you already drive a 12 or 18 Nm base near its limit, if you want the cleanest signal at high strength, or if you build a long term Sport or Pro setup. No, if you drive mostly at low strength, if you use a compact frame or desk mount, or if you prefer to spend the difference on better pedals. A strong load cell brake often improves lap times more than extra torque. Browse all Simagic direct drive bases at SIMGASM and compare the four torque levels side by side.

Setting up 28 Nm safely
A few habits keep a very strong base pleasant and safe to use.
Start with the overall strength low and raise it step by step. Keep your thumbs outside the spokes, as a sudden kick at 28 Nm is strong. Bolt the base firmly to a rated wheel deck or front mount. Route the cables cleanly along the profile, because loose plugs are a common cause of drop outs, as you read in our guide on why a Simagic wheelbase disconnects.
Questions about the Simagic Alpha EVO Ultra
Short answers to common questions about this base.
Does the Ultra fit a SIMGASM Hobby or Club?
No. SIMGASM lists only the Sport and Pro tiers as compatible with the Alpha EVO Ultra 28 Nm.
Is 28 Nm too strong for beginners?
Not if you set the strength low. Still, most beginners get more value from a 9 or 12 Nm base and better pedals.
Does the Ultra work on a console?
SIMGASM lists the Ultra for PC use within the Simagic ecosystem.
Can I use third party wheels on the Ultra?
Yes, with a correctly specified third party wheel and the right quick release adapter.
