yeah the little vibrations there where have dissapeared now that they are broken in but the car still feels much tighter than before also makes the exhaust sound a litte better
I went from the inserts to the dog bone. Vibrations are way more noticeable with the dog bone. But I've only had them on for about 300~400 miles. Everybody say they settle down around 1k. Also it's been cold 20~30 degrees so that has more vibes as well, when it was 70 here I thought the vibes were way better. Now the car does seem tighter and when you hit the pedal or let off the pedal it doesn't jerk nearly as much. I think it was worth it however the vibes may deter some people. But for the improvement in the way the car feels when you hit the pedal or let off I think it's worth it.
So basically the dogbone is better at doing its job.
