But remember, the RalliArt's S-AWC is still far different to that of the Cross. The Cross' is more alike to the Outlander than it is the Evo. So, even though the RA rear diff is just an RS (torsen), the RalliArt's ACD is always going to be more responsive than that of the Cross, by design. And has different programming altogether. Remember (if you didn't already know) it's not activated by wheel speed sensors alone (braking moment, like Scoobies, etc), but by calculations against yaw, pitch, and slip. That's why, to activate torque vectoring on an Evo X, you ACCELERATE, not brake.
This is what people who don't drive an Evo X do not understand. Yes, it's counterintuitive - but that's why it's fucking awesome! (The Cross comes close, but not quite.)
In any case, it does make me wonder whether you could use the DCT-470 and ACD from the RalliArt, and still retain use of the active rear diff on the Cross. How? Dunno. Less electronics, aye. But I wouldn't know what you'd need to do to retain that function with either TCU. The Cross does have torque vectoring, which does make it more fun to drive around twisty roads than the Sport/ASX. And that's why I say get a wrecked Evo rather than a RalliArt instead. Because if you wanna stick to the Torsen, then say goodbye to your Active Rear diff.
Whatever it is that you end up doing, though - just be aware that it's not as simple as you might think. If you're looking at a drivetrain swap, you'll need to drop in the TCU as well to control the SST and ACD. A GEMS or MoTeC Center Diff controller might help, but your factory TCU won't know what to do with the SST.
