I have the front and rear anti-sway kit for my 6th gen 4cyl coupe. Getting ready to install the new bars when I realize the box has included two bushings for a 28mm bar, and two for a 27mm bar. The front bar is in fact 27mm, but the rear is 19 i believe. Am I supposed to reuse the stock bushings for the rear bar, or did Eibach package the wrong bushings with this kit?

 

The rear is 19mm OEM. I'm guessing the sizes of the bar 27mm front, 23mm back? Might of sent you the wrong ones

 

The Eibach rear sway should be 23mm, and you're OEM rear sway should be 17mm. They must've packaged the wrong bushings.
