Hasport vs 27Won Motor Mount

Im looking to get the rear motor mount but indecisive of what i want. Anybody have any feedback from both sides. How is the drive the first couple days vs month later?

I have hasport 62a durometer (street version). It works for its intended purpose. Feels like the engine is solid mounted vibration wise at 1k rpm. It never changed for me in 20k miles. I adjusted my idle to 1100 and its been great ever since.

There's some discussion there as well. I have the 27WON. NVH is harsh at first. From Engine Braking to slight throttle in the 1-3 K rpm range. I've had it almost 600 miles now and there is still some NVH, although its much reduced from initial install. Some say it goes away almost completely after 1-2K miles, so I'm still waiting to see if that happens, but would be fine if the NVH stays about the same as it is now.

Would recommend Cusco RMM over everything!

You had to adjust your idle? I have the same one and my car idles fine. It's moving from a stand still that makes it obvious there's something there that shouldn't be

That's exactly why i did it. The car will idle wherever. Ive tried numerous different settings even down to +/- 25rpm incremental changes at times. The resonance range is 900 through 1050 rpm. Mine hasnt idled less than 1100rpm for around 18k miles. It's butter smooth taking off and consistent.

I posted about this in various other threads as to what i think the other benefits are for the long term.

I encourage anyone with a rmm to try it out.

Doesn't that change how you have to use the clutch now? I feel if my car was idling at 1100, I could take off without much throttle input if any... I had a B16 swap that idled high and I never even needed throttle to start off lol

Yeah i barely finesse the gas now to take off basically right off the higher idle. Less than 1500 rpm. I have the 2step at 2000 by default as well. XD

Sounds crazy but functions perfect.

My inexperienced manual driving wife could get me home or to the hospital in an emergency with minimal effort... you basically can't mess up the take off.

A/C compressor engagement barely effects the car and freezes me out. No battery issues in 21k miles. More consistent fluid temps. Better for the catalytic converter. stable oil pressure (unverified but logically has to).

And no resonance at take off.....

All at the cost of a negligible increase in fuel consumption

Yall think they feel comfortable idling at 720?

I put the HardRace RMM on my Si. Although it has a slightly higher durometer rating than the Hasport 62A at 65A. It's manufactured with air gaps like the factory RMM. This allows for an almost factory like idle, while holding the motor slightly more firmer than the 62A. You can see my review of the HardRace RMM Here.

Past that our cars "throb" with a serious intention. What your tolerance level is for that is an individual thing.

I would not. Photos of one recently surfaced where the bushings literally shredded themselves after about 10K miles of normal usage. I purchased a Cusco mount and I was going to be comparing it to my 27Won mount that I've had installed for over 10K miles, but now I will be selling the Cusco.

I recently installed a Hasport 62a rmm NVH was very noticeable at first especially at idle and low speeds (0-5mph)
Now though seems to have smoothened out orrr I just got used to it haha anyway it's a great mount and I think it's perfect for a street car

How do you go about adjusting your idle? I have Ktuner v1.2-is it a setting there?
