I put my motor mount on.

OK wow. I knew people said is was gonna be harsh and I thought I was prepared for it.

I was not.

First impressions, there's almost no vibrations at idle, which is cool, that's where I kinda expected it to be. It's not, all the NVH is felt in low RPM (>2000) driving, it's still not too bad, I'm kinda into it. Also nice is the response of the engine is IMMEDIATE. I knew I could feel the engine/transaxle rocking under certain situations but I didn't know exactly how much moving it was doing until it couldn't. The engine exhaust note also seems a tad louder and a little growlier? Does that make sense?

However.

When the engine boosts the whole car turns into a HITACHI WAND. Now that the engine is firmly bolted to the chassis all of the engine harmonics are transferred directly into the car and everything in it. It's not exactly unpleasant I just expected the engine to be smoother under boost. I can also tell it is engine harmonics because the vibrations match with the exhaust note perfectly.

Pros: No more rocking, snappier pedal, fun noises, girls will like it
Cons: BUZZZZZZZZZ on boost, I installed it wrong the first time.

I need more seat time to really have an opinion.
