Eibach Pro System Kit?

ZF Sachs makes the dampers in Mexico.

I posted a shock dyno curve of one of the ones we tested a while back. The dampers are junk.

Go with Tokico or Bilstein, especially Bilstein monotubes and you'll be better off.

what kinda problems? i put the pro kit on the rear of my car after i put my new uppers and lowers in, and i thought they rode like crap, and i had a weird wheel hopping issue. i put the stock rears back in and it went away. and those shocks suck. not that mine are much better, i got the kyb agx's. they're adjustable, but i cant tell the difference between 1 and 8 on mine.
