What do you think is the best rear motor mount?

I am holding on to my ST so I would like to know what people find to be the best aftermarket motor mount.

I installed the mountune RMM this weekend and I love it. I think it's considered the softest of the multiple options (Cobb, Boomba) out there but it really seemed to clean up the shift action and I haven't noticed any NVH.

I can't say which is the best, but I'm completely satisfied with my Cobb RMM.

Best is going to come down to what you want.

I've only experienced the Mountune RMM and I have zero regrets. Just the tiniest bit of barely perceptible added vibration at hot-idle-only, and prominently improved shift precision.

Problem is unless someone has tried more than one they would say there's is best. From reading the theads the Boomba seems to take the longest to mellow and therefore the stiffest. I personally love my Mountune and made a huge difference over stock.

We can recommend the Boomba mount, but we may be slightly biased

Honestly though, if anyone has any questions about our mount please ask. Our mount is nice because you don't have to hammer the stock support bracket to reuse; ours comes with a new one.

From the research that I did online had considered the COBB but then I read about 1 or 2 people with this one that experiencing the banging issue after installed. I also like the CPE design but ultimately went with the mountune one and love it, no more banging with aggressive driving and can barely tell any difference of NVH compared to stock, it's the best of both worlds.

After much research I went with the Mountune unit. Will be installing Saturday.

I did a write up on my opinions on the Boomba and Cobb. I had both. Never had the Mountune but I hear it's more like the Cobb, and possibly even softer though it may not be a discernible difference.

So far I haven't noticed any vibrations with my Mountune RMM. It's the new black one (not the previous yellow version) if that matters. I tend to drive my car fairly easily 99% of the time so I haven't really noticed much of a difference. I never shifted my car hard enough to notice any "banging" with the stock RMM though.

If you are going by durometer than the "softest" mount would be the Breedt which has a 45 rating and a 65 "track" rated bushing that you can change over to if you so wish.

I don't know but I installed my cobb rmm today. I've had it since I bought the car in February. It's raining so no test yet. But tomorrow I'm going on a mountain st cruise which should be a good test
