It doesn't seem to matter what gear I'm in but I'm getting a pretty bad vibration while I'm accelerating. My car is a 2010 GT. In the last week I put the pypes Violator axleback on it, eibach prokit and had it aligned, new tires and wheels and then last was a Hurst shifter. I know i need to get an adjustable panhard bar since the rear axle is sitting to one side a little. I didn't really notice the vibration until after I put the shifter in but I'm guessing most of that has to do with the fact that it's so much more firmly mounted. I was going to throw the old exhaust back on it to see if that changes anything but I have a pretty good idea that it has to do with pinion angle.

The question is, is there much benefit to getting upper and lower control arms? My car is pretty much just a daily driver that's not very likely to see a track more than a few times. Also, would a one piece driveline potentially solve the issue?

Thanks
