Group-N Most EJ motors and 5 speed transmission Mounts
The engine mounts definitely help keep the engine still when the car revs high. Zero complaints other than increase NVH at idle. It was to be expected so it's a feature that you can definitely overlook. The transmission mount is a completely different story. Holy cow did this change my driving experience. I had spent so much time installing stiffer bushings all around the shifter assembly but this was the final piece to the puzzle. This trans mount make shifts much smoother, especially with quick shifting. If you don't do your motor mounts you NEED to do this mod. Alone it costs about $75. Small price for big benefits.

Mileage at Install
Way easier on a lift. You will have to do jack up the motor to switch mounts. Using a trans jack will make the job super easy. Expect an install time of about 3 hours for first timers and half that for people with experience.
