I just finished making this video about why your Fiesta ST needs a Rear Motor Mount upgrade.
I don't normally make this type of video so go easy on me
I have been thrilled with the improvement they've made in the car and that's been the general consensus amongst those who've fitted one.
You can also go the powerflex route or 2j racing, all of these will be a great improvement to the car, but you have to be careful not to go too harsh and require a bit more work to swap in/out. As a direct bolt on solution, I think the Cobb engineers knocked it out of the park with these.
Anyways if you've wanted to know why you need that RMM upgrade, I put together this video explanation of why it should be one of the next upgrades on your list and address some common concerns for those considering the RMM upgrade.
I also just put together this post on the ModBargains blog explaining it in further detail as well if you'd like to check that out
Interested in ordering a RMM? While I can't give anyone pricing etc (I'm not in sales), I can answer any technical questions you may have about the RMM or other Fiesta ST specific tech questions.
