There was a slight increase in vibration from 1500-2000rpms but I actually like the way it sounds and feels. Other then that, it's like driving a totally different car. It feels like the suspension is actually working better since I guess the motor mount weak and taking a good portion of the abuse. It's raining like ass & **** over here but for some reason my traction in the rain is better then it's ever beeen and that's weird but a very good thinking. I sterring wheel also stopped shaking. I thought my rotors were seriously warped again but come to find out, it was the motor mount worn.
