renewed life for old suspension?

[Chris Krahe]

Hey-

Sad to say, but I recently took money saved for a G35 and put it toward home
improvements.  What was I thinking?  Anyway, I now plan to put a few bucks
into my NX to make it a bit more fun for at least another year.

The car: '93 NX-2000 with ~105,000 miles, stock except adjustable KYB struts.
This is my daily driver and occasional autocrosser.

The story: The suspension feels a bit tired.  I'd swear body roll has
increased 25% in the last 20K miles.  Feels a bit floatier at speed these days
(not bouncy, like bad struts would do, but vague).  KYB's still feel like
they're doing their job.

The first question: Could the suspension woes indicate old springs?  Other
stuff?

The second question: Looking for a cost-effective solution to make the
suspension feel as good as it was, say, at 60,000 miles.  New is fine sure,
but don't need anything better than stock.  And like I said, I'm only keeping
the car another year, so no need to sink big money into it.

Ideas?  Suggestions?  Condemnations for delaying new car?  Other comments?

Thanks in advance .....
