OBO bump

I have a set of low mile Mazdaspeed comp mounts, that if some one wanted to to the hybrid set up, but I will only consider this if I can get both sets sold at once.

can i ask?
how do you compare the MMR to the Roadster tuner mounts?

im not concerned with NVH. so i dont want to hear about that .
but do the MMR tend to loosen up ? will they really hold that motor in place.
my car takes a major beating . my RT's seem to need retightening every so often.

I've got the old drifting jellyfish mounts. (essentially same style) I re-torque the all thread nuts and the motormount cups on the motor after every few track days. They will get loose overtime and depending on how you use your car.

ok,
so i hope this isnt normal.
you guys would cringe and cry at the abuse i put my car through.
i have to retighten mine every 2 events , it seems , not happy about that.


my concern is the all tread ,through bolt ,needs a nut on top to hold it. it really needs to be held while torquing it down . which cant be done unless the mounting plate to the motor is off .

Yeah, I took the mounting plate off and torqued from both ends. I also check the three bolts that hold the plate to the engine block.

I would consider the MMR more responsive than the Roadster Tuner, and the roadster tuner are day and night more responsive than the MS comp mounts. With the MMR clutch less shifting was super easy for me, while with Roadster Tuner its still pretty easy just not as easy as MMR. And for NVH the RT have a decent amount at idle to 1.5k and after its noticeable but not bad at all, it comes across as more motor noise.

With MMR the motor pretty much does not move... At all. I never put nylocks on the MMR because I didn't run them very long, I put them in and within a week my Miata got turned in to a daily and I didn't want to deal with solid mounts.

But +1 on the Nylocks on the RT
