Same 12 Nm, very different value. The R12 V2 comes in a full $300 below the ClubSport DD 12 and scores higher on our rubric while doing it - crisper kerb detail, every bump coming through, for the price most brands charge for a wheel and base together. Judged purely as a wheelbase, the MOZA is the stronger product and the cheaper one, which is not a combination the Fanatec can argue with directly.
So the ClubSport DD 12 has to make its case elsewhere, and it does have one: the ecosystem. Fanatec's QR2 and its rim catalogue are the deepest in the business, and if you already own Fanatec wheels, or you want the broadest choice of rims to hang off a base, the ClubSport keeps you in that world. That platform pull is genuine - it is just not worth $300 to someone starting fresh with no Fanatec gear.
My take: if you are buying a base to build around from scratch, the R12 V2 is the smarter money by a distance, and the $300 you save buys a much better wheel or pedal set. The ClubSport DD 12 earns its place when the decision is really about staying inside Fanatec - existing rims, existing pedals, one connected system. On the hardware in isolation, MOZA wins this one.
