Your front rotors do look wrong.
OP's rotors are the correct ones. Brembo Europe uses D-type bobbin hats vs the H-type bobbin found in the many US kits. The vane direction and the direction of the cross drills are correct for the kits that we get in Europe.

As to the vibration, I would check:
1) the D-type floating assembly is clean and torqued properly to Brembo spec.
2) the mating surface between the friction ring and the hat is clean.
3) the mating surface between the hub and the hat is clean.
4) check for friction ring runout when the entire brake disc assembly is on the hub.

If there is lateral or radial runout, the mechanic will then have to determine whether the runout is due to the brake disc/hub assembly, or due to uneven pad deposit (which does not contribute to radial runout however). Any reputable mechanic will know the steps to determine this.
