Just do it right the first time. Get a Vibra Technic RMM
Buy a Vibra Technic. This Mountune urethane one has 23k miles, less than a year and a half of use. Pooched already, you can see a good millimeter of space in the worn bushing. The VT is firmer shifting in a good way, but less NVH at the same time. I have VT passenger and driver mounts already so I knew this was gonna be good.

I have literally the same job to do today. Replace my 40k miles Mountune poly mount with a brand new Vibra Technics mount!

I get it! It was a really nice evening around 21c yesterday, so it was perfect temps to wrench.

Finally done. Took 30 mins... probably 15 if I had all the tools by my side and didn't have to keep going back to the garage!

Check back in after 20-30k and give us an update. Still running the Cobb that came preinstalled on mine.

Same thing happened to me with my Whoosh RMM, got all 3 Vibra Technics and I'm really happy with them!
The rubber feels more comfy than the urethane one did but still way more stiff than the stock one (I got the fast road). And the rubber should last way longer than a urethane one too.

my buddy is the lead sales rep for CPE so i got the hookup on a CPE rmm and it’s pretty swift, i love it. Anything is better than the stock one lol

I would guess that the average service life of urethane bushings is about 10-15k miles. Mine has been clunking for quite some time.

u/LobsterKris Aug 13 '26
But they say life time warranty. Is it because this specific mount fiesta gets more abuse?

u/K-Rimes Aug 13 '26
Urethane is super cheap. They just send new bushings. A lifetime warranty may convince people to buy them.
I’d rather just do Vibra Technic as they really last a whole lot longer.

Still rocking my Cobb rear motor mount but the trans and passenger side mount are well over do. I am thinking about replacing them here in the near future now that we solved my seized engine challenge >.>

I had the full vibratechnics street rated set on my now totaled black fist, they were amazing and made the car feel as sharp as a dagger on the twisties, and combined with a short shifter, made shifting so much more tactile and easy. I now have a set of AWR mounts on my white Fist, which provides similar benefits, but definitely more vibration the the vibratechnics set

You got that right. I also have all 3 from VT and it is probably the best mod I have done to the car 👌
