OK, so i just past 1,000 miles on the new motor mounts so i figured i put up a review...
The way it changes the sound while driving...

Pro:
1) On first startup there was a slight viberation that was felt in the seat and seen in the dash and such... but after 1000 miles there is now ZERO viberation.. I have a set of dog tags that hang from my rearview mirror that made a ton of noise the very first time i started it... Now they hang completely silent and make ZERO noise....I almost want to say its same viberation as stock mounts when they were NEW....
2) Before the mounts i could ride in 3rd gear and roll into the throttle from 1500rpms and spin the tires on dry pavement at peak boost....Now with the new mounts i have not been able to spin in 3rd yet... tried it multiple times in areas it spun on old mounts...
3) Shifting was smoothened and made Crisp... before the mounts i was chasing an issue with difficulty shifting from 1st to 2nd, 2nd to 3rd and adjusted the Sigma Shifter a dozen times with no success... after mounts install the clunky shifting i had before is completely gone...and shifts now like a brand new OEM car...
4) Interested in how it affected my car, i know on diesel truck world just upgrading your motor mounts you can see an increase in spoolup on turbo due to the initial torque of the motor softening takeoff. Diesels build boost faster the more load you put on them in most cases....
Well... i did 5 x 3rd gear pulls the morning of the mount swap and later the same night when temps were cooled off around what the morning pulls i did... i did 5 more pulls in 3rd... not only did i no longer get wheel spin on some pulls anymore... i also averaged 112rpms sooner on peak boost vs old mounts...
5) taking off from a stop is 1000X easier with aggresive clutch engagement now.. before it sometimes tossed the motor around causing take off to not be smooth sometimes causing the car to chop almost...
Cons
1) The drawback i have is there is resonation issue that im working on.. at idle i hear the injectors firing, i hear the pulleys spinning, and i did hear the fuel pump hum also.. but i redid my bracket for the fuel pump and its gone now..
During acceleration i hear resonation of the injectors and pulleys spinning distinctive.. Also i HEAR when the vanes on the turbo open and close. I am talking with the manufacture to possibly come up with a solution to this.. Thinking of mounting a layer of silicone between metal on metal surfaces to limit the area of resonation.
2) The OEM mount is where the OEM fuel pump is mounted. The OEM mount top doesnt move but the new mount top does move with the engine making the mounting of the fuel pump an issue. I had to create a bracket off the mounting bolts that mount the mount to the body and rig up something for the pump to mount to. I origionally zip tied it to the top of the mount not realizing it that it moved... when i turned the key to the on position before starting the motor.. there was this hum heard... it turned out that the fuel pump was huming through the engine mount into the cabin...
