Driveline Slop Anyone???

I have finally gotten the SVT how I want it but have one more issue. Well, i dont know if it is an issue and thats why I am starting the thread.
I wanna know if anyone else experiences the "driveline slop/backlash/slack" that I experience when I let off or apply the gas from a coast especially in 1st -3rd gears? If no-one else experiences this imagine you are driving along at constant speed in a parking lot in 1st gear and are coming up to a stop sign. You take your foot off the gas and are immediately jerked forward in your seat as if the tranny suddenly catches up to the motor. It is something that I found I can minimize by being VERY gradual with the throttle peddle, but I wanna know if I have a problem or if this is "normal".

I know the SVT cobras all do this and people say its just because its a performance car...is that the case with our SVT Focii as well?

Thanks for the responses in advance!!!

Well, with all cars I've driven, especially in first gear, you have to be smooth with the throttle to not get a kickback due to the compression from the engine and its ease to twitch the driveline in such an easy gear. It's actually great to have the compression work so well because it slows you down nicely when taking low speed turns without having to use the brakes.

I get twitches in the driveline due to extremes in terms of throttle application or low gear throttle lift, but I blame that mostly on the rear engine mount for the engine movement allowed. It really doesn't actually make the car less annoying and compliant, it really interferes with the driveline's smoothness.

You still have the stock motor mounts dont you........ stock mounts allow ALOT of engine/tranny movement.

You'll experience that in just about any manual transmission car in gears 1 and 2 and most of the time 3 if it's geared right. What you are experiencing is gearing, backpressure, and due to the stock mounts you get the backlash effect where the driveline rotated as far as it can one way pulling on those mounts when under acceleration and then when you let off suddenly it jerks back as far as it can in the other direction because of the gearing/backpressure.

If you swap out the lower mount with either the VF or MAC piece, that will help a lot with engine movement like that. Don't bother with the inserts, they SUCK, mine keep slipping out of place, VERY annoying!!
