Just edited my post on the rear suspension components.
The blue part is known ONLY as traction rods not toe rods (they can adjust toe to an extent if they're aftermarket adjustable pieces). In the HICAS model, the tie-rods, just like in the front, are responsible for adjusting the toe. On a non-HICAS subframe their are arms that extend from the rear of the cradle to the spindle/knuckle that are known as toe-rods.
A sweet site displaying what adjustments can be made using what components and their possible effect.
