Shudders on take off

[Aluma007]

Is it normal on start up? I back out of the driveway, stop, go forward and it always feels like the brakes or something shakes out back. Got to the point I upgraded to max performance tires and its been reduced by quite a bit, but it still does it. Keep thinking something is loose or broken but everything seems up to par down there. Do you all experience this as well? would those subframe inserts cut down on that?

Might it be that you are referring when one loads diff, it jumps/shudders around in stock mounts? If that bothers you, you can always turn to aftermarket diff mount bushings.

Did you buy the car new
Has it always done it
Have you driven many stick cars
does it do it when any one else drives it
Does it change when it gets warm


Do you have a video

Yes
Yes
Yes but this one is AT
Yes
Sometimes

No vid, Its a seat of the pants vibration...sometimes you hear it too though, but it might be the tires slipping against the pavement.

Af far as the diff, I have no idea. But it does seem to be worse when turning right at the end of my street vs left.

If the front wheels are turned, it's the diff locking and spinning the inside tire.

Mine does the same. It's the differential. That means it's working correctly. Right turn is sharper than left turn so that's why it is more pronounced.

so its okay when its going straight on take off? even on slow or fast acceleration? Guess its quite different than the limited slip diffs on honda Si's...that thing never shook like that. LOL Well, it's my first RWD car so I guess it's something I have to get used to. (had the car for two years now hahahaha)

Hmm if you are going straight and not on uneven pavement it's not likely the diff. It's possible you have an alignment issue, but possible doesn't mean probable in this case.
