Wheel rims and quick-releases: compatibility and ergonomics

A quick-release (QR) is two halves, not one. The base-side half sits on the wheelbase shaft; the wheel-side half bolts to the back of the rim. Both must match before a rim will mate. Buying a wheel advertised as “QR2” does nothing if your base still carries a QR1 base-side, which is the single most common point of confusion when people start swapping rims.

What a quick-release actually is

The QR lets you pull one rim off and click another on in a couple of seconds, so a formula rim and a GT rim can share one base. The mechanical mount under the rim is separate from the QR itself: almost the entire industry uses a 6×70mm PCD bolt circle (six bolts on a 70mm pitch-circle diameter) on the rim’s mounting face. Fanatec, Moza, VRS, Simagic, Simucube, Cube Controls, and Ascher all build rims to 6×70mm. That standard is why a rim physically bolts to so many adapters, but the bolt pattern alone does not make the electronics talk.

Buttons, rotaries, paddle shifters, and displays need a native data connection through the QR. These are the same controls you would otherwise add with a button box. Pure-mechanical quick-releases (cheap NRG-style or AliExpress 70mm units) pass torque and nothing else. They are fine for a rim that has its own separate USB cable, and useless for sending button data through the hub.

Fanatec QR1 vs QR2

QR1 was the older plastic system, and its wobble and play are the reason “QR1 sucks, QR2 is great” is the standard verdict. QR2 is the current standard: a diecast, anodized aluminum wheel-side with no detectable play. The two generations do not mix in either direction, which Fanatec states flat: “a steering wheel equipped with a QR1 is not compatible with a wheel base equipped with a QR2, and vice versa”. Fanatec specs the QR2 base-side clamp-ring bolts at 8 Nm, which is how tight to do up a fastener and is unrelated to the 8 Nm wheel-torque ceiling in the next paragraph.

QR2 comes in three wheel-sides: composite QR2 Lite on CSL wheels, diecast aluminum QR2 on ClubSport wheels, and CNC-machined QR2 Pro on Podium wheels. All three mate with every QR2 base-side, so the tier is not a fitment question. It is a torque question only on some CSL wheels, and there Fanatec’s own pages contradict each other: a base listing says every QR2 Lite wheel caps that base at 8 Nm, while a Fanatec news article last updated 2 March 2026 names seven wheels that are not capped. Which is true of your rim is stated on the rim’s own listing. The Fanatec QR2 guide quotes all four statements, lists which base and wheel ships which tier, and prices the upgrades.

Some old Fanatec wheels are stranded, and the three most often asked about are the three Fanatec rules out by name. Its QR2 page carries a heading reading “Legacy Steering Wheels not compatible with QR2:” over ten products, and among them are the ClubSport Universal Hub, the ClubSport Steering Wheel BMW GT2, and the ClubSport Steering Wheel Formula Black and Formula Carbon. Fanatec sells no wheel-side that fits any of them. What it does list is eighteen wheels and hubs that take a QR2 wheel-side, split across two lists by whether the composite QR2 Lite is allowed, and the Fanatec QR2 guide sets out both lists and prices the parts. The V2 revisions are the ones that made the cut: the ClubSport Universal Hub V2 and the ClubSport Steering Wheel BMW M3 GT2 V2 are both on the upgradable list their V1 predecessors are excluded from. Third-party adapters are the route left for a legacy rim, and the section below covers who sells them.

Moza, VRS, Simucube, Simagic, Thrustmaster

• Moza QR. 6×70mm PCD, a ball-lock plus push-pin design in aviation-grade aluminum, fits the whole R5–R25 lineup. Mount a third-party rim via a Moza QR adapter and you get FFB, but the buttons, encoders, LEDs, and shifters need the native Moza data link. They will not work through a generic adapter.
• VRS DirectForce Pro. Standard 6×70mm wheel-side, ships with both threaded and non-threaded adapters (5mm bolts). One of the most openly compatible bases out there.
• Simucube. Three connection routes rather than one coupling, and the route decides more than the bolt circle does. A USB wheel plugs into the PC and works on either base generation; a Simucube Wireless Wheel talks to a $159 Simucube Link Hub over radio and runs on its own battery; a Link Wheel takes power and data across the joint itself, through the $169 Link Quick Release, which Simucube rules out on a Simucube 2 by name. The one older coupling and the new one bridge both ways for $99 and $69, and Simucube says wireless power and data survive neither bridge. The Simucube Link guide reproduces Simucube’s own five-column route table, prices all eight parts, and sorts its ten wheel listings by the route each one names.
• Simagic. Two parts named for their bolt circles rather than for a generation, the QR50 and the QR70, sold as two variants of one $79 listing whose only sentence is “QR70 for GT1 series & P-325D & P-330R series , QR50 for other series”. Simagic is the one brand here that sells a route around its own data link: the $89 QR-A carries a third-party wheel’s USB into the base’s second input, and Simagic rules it out by name on the M10, Alpha Mini, Alpha, and Alpha U. Going the other way, a current Zeus or Neo X wheel on one of those older bases needs a $45 Maglink Pro or an $89 Maglink Pro Xtend. The Simagic QR guide counts which wheel names which part and sets out both bridges.
• Thrustmaster. Two fittings, and Thrustmaster’s own box lists name them the “screw base” and the “latch base”. Screw is the older T-Series mount on the TX, T300, T-GT, TS-XW, and TS-PC; latch is what the T818 introduced and the T598 uses. An older rim reaches a T818 or T598 through a $54.99 Quick Release Adapter that unclips or a $44.99 Quick Release Upgrade screwed in permanently, and Thrustmaster publishes three lists of which rims take which that do not match. The Thrustmaster quick release guide sets the three lists side by side and counts which rim in the catalog ships which fitting.

Mixing brands: the escape hatch

If you want a third-party rim with full force feedback on a Fanatec base, the Simube QR2 Ultra carries a torque-unlocking chip (turn the wheel 90° right to unlock), so any 70mm third-party rim gets full Fanatec FFB on a QR2 base. SimRacingMachines (SRM) sells QR1-to-QR2 and cross-brand conversion adapters for nearly every combination. These exist precisely because the data connection, not the bolt circle, is what blocks cross-brand setups.

Formula vs GT vs round

The rim shape should follow the car you drive.

• Formula rim. Open-bottom D-shape or oval, roughly 280–300mm wide, with fixed hands at 9-and-3, paddle shifters, a wall of buttons and rotaries, and often a display. You never move your hands. Best for open-wheel: iRacing F4/F3, Skip Barber, FIA F4, karts.
• GT rim. Fuller, roughly 300–330mm, suede or rubber grip, usually with a thumb rest. Best for GT3/GT4, touring cars, and prototypes, where you do move your hands and want a complete grip surface.
• Round wheel. A full 280–360mm circle (Logitech RS Round Wheel 28cm, Moza round wheels) for rally, drift, and road cars, where you cross hands and run 180° or more of rotation. A formula rim is miserable for rally because the open bottom gives you nothing to grab mid-corner.

Match the rim to your discipline first, then check that both QR halves and the data connection line up. For specific wheels by shape and budget, see the steering wheels overview and its per-model reviews. For the base under it, see wheelbases and how the wheelbase brands compare; your base dictates which QR and rim ecosystem you are locked into.
