Fanatec QR1 vs QR2: what actually fits

The answer, before the nuance

A QR1 wheel does not fit a QR2 base. A QR2 wheel does not fit a QR1 base. Fanatec sells no adapter between them, and says so on its own comparison page. If you own QR1 hardware and buy into QR2, you replace both sides or you replace neither.

That is the part most pages get right. Everything below is the part they get wrong.

QR2 is not one interface, and that is where builds break

Roundups treat QR2 as the destination: an upgrade you make once, after which everything Fanatec bolts to everything else Fanatec. That is not what the documents say.

QR2 ships in Lite, Regular, Pro and Type-F variants. The sourced statement on the CSL DD page is specific: the QR2 Lite base side is compatible with all versions of the QR2 wheel side. That sentence is doing narrower work than it looks. It licenses Lite-base-to-anything. It says nothing about the other direction, and nothing about Type-F.

The ClubSport DD ships a Type-F base side. So "I upgraded to QR2" does not tell you whether your wheel mounts to a ClubSport DD. It tells you which family you are in, not which connector you have.

That distinction is load-bearing enough that this site tracks Type-F as its own interface code rather than folding it into QR2, precisely so a build cannot inherit a fit it was never granted.

Fanatec's own pages disagree with each other

Here is the part that should make you slow down.

The CSL P1 V2 page lists the ClubSport DD among that wheel's compatible bases. The GT Forza Motorsport V2 page, for a wheel carrying the same QR2 wheel side, omits the ClubSport DD from its compatible-base list entirely.

Same manufacturer. Same quick release on the wheel side. Two lists that cannot both be current. One of them is stale, and there is no way to tell which from the outside.

This is the second time a Fanatec compatibility list has left out their own newest base. The GT Forza V2 list runs Podium DD1 and DD2, ClubSport V2 and V2.5, the CSL Elite variants, the CSL DD and the Gran Turismo DD Pro, and stops short of the ClubSport DD. The likeliest explanation is that the list predates the base rather than excludes it. Likeliest is not sourced.

So the honest position is the one this site takes: record the interface-level claim, which is sourced, note that a product-level list contradicts it, and do not pretend the contradiction resolved itself. A page that told you confidently either way would be inventing the confidence.

The torque caveat nobody carries

A QR2 Lite wheel side limits some bases to 8 Nm.

That is worth stating plainly because it is easy to misread in both directions. It is not a fitment failure: the wheel mounts, the base works, nothing is damaged. It is a ceiling. If you buy a 15 Nm base and put a Lite wheel side on it, you have bought headroom you cannot currently use.

Roundups drop this because it does not fit a compatibility table. It belongs in one anyway, because it is the difference between a spec you paid for and a spec you receive.

What to do with this before you buy

Three checks, in order.

Confirm which QR generation each side of your pairing has, not which the product family has. Confirm the specific variant on the base side, because Type-F is not covered by the Lite statement. And if your intended pairing involves the ClubSport DD and a wheel whose page does not list it, treat that as unresolved rather than as a no: the interface-level evidence points one way and a product page points the other.

The two products below are the pairing at the centre of that contradiction. The stamp on each reads its own sourced claims, not the pairing.
