Depends on the suspension, but typically that's one component I would prefer to buy new. People will say all "highway miles" or only 5k on the suspension and you have no idea really... I guess use your judgement on what looks to be in good shape. I would like the satisfaction and comfort of brand new dampers covered by a warranty of some type.

I think I saw the PSS10 on ZSpeed, but not too sure. Back in my BMW days Ground Control let you essentially build your own setup from scratch. Custom spring rates, spring lengths, dampers custom valved etc. It was sweet if you wanted to do your own thing and knew how to setup a car. I had a nasty suspension setup for my STi with custom double adjustable Koni dampers with independent rebound and bump adjustment. Too bad they don't have any offerings for the 370Z.

I tend to like European designed dampers. The critical dampening rates tend to be much lower so it's a lot more compliant over bumps which makes things a lot easier on the car for longer term durability and comfort. Softer doesn't necessarily mean slower... Gone are the days of super stiff, bone shattering suspension for quick times. I haven't explored a whole lot myself for the 370Z because I just got one and I like the car stock right now, but I would explore Bilstein, Koni, KW and other offerings before going straight to like BC, Cusco etc.

There's two or three 370Zs that race in the Continental series or whichever the series is. They're at Lime Rock Park this weekend. I think one of the guys on the team is on this board, but I would consult their experience to see what setups they've been running for the best real world advice. When I choose suspension I consider price, durability, warranty, dampers/springs offered.
