My first and only experience with the bounce was on I294/80 west near the ILL/IN border with 1800 miles on the Z at the time. I now have about 2700 miles and have not experience any bounce since the first time, but I have not been back on I294/80.

I have just installed a set of Eibach springs and I would like to test them out on a road that causes the Z to bounce. Preferably some where in the NW suburbs.

thanks,

The best test would definitely be the section you mentioned, on westbound I-294 between the exit for I-55 and the exit for I-290. But if you'd like to stay closer to home, Higgins between Barrington Road and Roselle Road in Schaumburg/Hoffman may work.

 

You can also try 355, just south of the toll. The road looks smooth, but man does it start to bounce. It seems to be the worst at around the speed limit. Good luck. Let us know if the springs cure it.
