they're not cup racer engine mounts, they look more like grpN units
Heres the info in badly translated German.
These strengthened hanging up elements for the Clio2, 2,0l 16V R-S are racer-rehearsed in the Gr.N and in the Clio Coupe. They prevent effectively a tilting of the engine gear unit with the load change and when switching. Thus safe, accurate switching is possible (many damage to the engine results on interconnecting into a too low course) and also the negative load change reactions of the vehicle decrease clearly.
For all width sportsmen and drivers with sporty driving fashion we recommend the installation of the strengthened torque support. For the hard engine haven employment also the other strengthened hanging up should be used.
