It worked on my Juke. Made the car drive better. Handle better. Respond to throttle input faster. Trade off as mentioned above is more cabin noise.
I cannot say what this will do to a SHO as the mounts are in different locations and are different design. I was just offering a different way to do them that works really well.
Buy a used or new set of mounts. Mod/Urethane them. Then you can swap them out for Long trips, Servicing, etc with the unmodded mounts.
