Read this in Grassroots Motorsports Article on Shock absorbers. I am quoting here. "A spring that is not properly damped will cycle rapidly as a load is applied and removed. Picture a bobble head doll: The spring inside the doll's neck keeps whipping that head around long after the doll stops moving. The same reaction can be seen in a car fitted with bad shock absorbers. The car will continue to rock up and down after it has finished going over a bump or through a turn. In extreme examples, the wheel and tire will continually cycle up and down as the car is driven on a relatively smooth road." Sound like any car we know. I want some Konis.......The article is a good read and they test some Konis similar to what should be available for the 350Z soon.

 

I'm close to buying a new Track 350Z, haven't closed the deal yet. Are you saying the stock shocks are crap, and that you experience the pogo stick ride described? Hate to think I'm going to have to replace the shocks immediately.

 

Yup, welcome to the club . The stock shocks are not matched correctly with the stiffer springs.

 

Yes on some roads you will have the bounce.

It's not nearly that bad. Most people didn't even know it was an issue (certainly I never noticed until people kept pointing it out here).

Yes you'll want new coil-overs at some point in the future just for better control, but the stock stuff works fine for most driving.

 

People who have driven sports cars notice the problem.
