It should help! The Fiesta ST and Focus ST use different rear motor mounts, but we are working on a Fiesta ST version. I have driven our SEMA car with a prototype version and have another prototpye sitting on my desk for my car. Can't wait to get it in!
The wheel hop was so bad in the FoST I test-drove that it's one of the reasons I chose the FiST instead. It's present in our cars but much more subdued...a Cobb rmm is on my wish list though!
