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.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.
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.which cant be done unless the mounting plate to the motor is off .
