PMM on a daily driver?

[Yatta]

After playing much with the CorkSport PMM, I have went back to stock; Vibes with the CS mount were manageable and only crazy between 2k and 3k but the drone in cabin made it difficult to do anything but listen to the drone (messed with phone and radio use). After removing it I found that the rear bushing had been compromised, I purchased this used but remember while installing it thinking that the contact patch for this would be better if it were the entire length of the mount and was curious why the previous owner sent along a spare bushing... Either way, before placing the stock mount back in I had a look and noticed the ribbing had contacted the rear of the mount (lines where contact occurred) more than the front, I also noticed that a c clamp screw assembly would fit (a bit tight) in each corner. Couldn’t be any worse and I can undo it if I don’t like it with snips... so.


A slight bit of vibes on cold start, no noticeable vibes outside of 2k-3k, in the 2k-3k a slight amount of rear view blurring (only noticed because I was looking for it) but as soon as I nail the throttle it feels solid again (with vibes and all).

The clamps were 3.5” from home depot, the top rear would be better suited for a 3” but I didn’t care for this.. tightened enough to prevent movement, the back side bent in to allow torque for the stock bolts. I have only put 40 miles on this, will check it each day; going from CS PMM to ‘stock’ is a huge difference in cabin noise, before radio would have to be set at 45, now it is at 25 and I can hear it and wind noise again.

$5 at Home Depot.... maybe placebo, but noise reduction was the goal.

Yes, it is similar, no it is not the same, I considered full metal inserts and Window urethane but wanted something that I could remove if it didn’t work as planned; hose clamps could actually be put in with the mount in place and removed with a screwdriver or snips; I am pretty certain a lot here would not be willing to try JBWeld and Aluminum inserts but might consider trying the clamps. Either way, I thought it would be helpful to put this out here.
