I've had to convert the dedicated ax car (99 Boxster) back to daily driver street use and the harsh ride is killing me. I could use some input on how to approach this. I've found some really...um...diverse...info on other forums. BTW, "harsh ride" is subjective but I'm talking about sudden unforgiving jolts that rattle the whole car and shake parts of me I don't want shaking on the way to work.
Here's what may be contributing to the issue:
* pss9 coil overs
* lowered ride height
* Tarret adjustable sway bars and drop links
* possibly bad bushings?
I've been told that the PSS9s can be set to "softer than stock". I'd have to compare to a stock car to be sure, but I'm not getting that even at it's softest settings of the 1-9 damping adjustment. I'm no expert, but I was also thinking that the ride height shouldn't be causing this because these units allow that to be set independent of the spring settings. Is this correct? Are there even settings on the springs that I can adjust such as pre-load?
I'm also suspecting that the sway bars in their harder track positions would transmit more vibration through the chassis. Is this true?
As far as bushings are concerned, the car is old enough to need it but I'm not hearing the tell tale noises that most people are describing. I suppose it's probably worth doing anyway at this age.
Anyway, I'm just looking to get some basic info and educate myself before making any drastic decisions. Any input or advice would be greatly appreciated.
Thanks,
Mike
