Stock suspension done at 20k

cossie1600

KW is $2K and PSS10 Bilsteins are $2.5K. I am going to sleep on it to make sure they are really worth it. Worst case scenario, I might just pop a set of sway bars in to see if it will get me through the winter.

Can't really go wrong with thicker sway bars. If your dampers are toast though it will be a little like putting a band-aid on a broken arm. Ask around, see what others think, try and get a ride or drive a car that's running that suspension. KW is more proven on the 370Z platform than the Bilstein, but that doesn't mean it's better though.

Are they good to buy used?

I don't know if pss 10 is available. If so, I want to get a used set and have custom specs put in

IGoFast1589

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.

Have you checked your dampers yet see if any of them are leaking?
It's could also be a suspension bushing issue. You said it was leaning all over the place in the turns, was the car loose at all?
Also if your having diff issue that could be a cause of loosing time. I would also go over the whole car, and check out everything before trying to band-aid it with sway bars which could lead to another issue.

My two cent is, I really like the Tein coils. Flex and Mono Flex, and the EDFC is awesome to play with. Though some racing syndicates won't allow you to run it on course, and I hear good things about their new EDFC active. You can also get custom valving and have them rebuilt here in the states when the time comes.

Agreed! Check everything first man. EDFC does seem pretty cool.

If you really want to be serious about your coilover selection check out the shock dynos for the dampers. If you don't know how to read them I will read them for you if you post them up so you can get a sense of their behavior. Not sure if anyone has plotted any shocks for out of the box 370Z coilover suspensions, but they're nice to look at and can give you some key insight into how they will feel.

KW V3's are a good product, sort of like a super enthusiast product. Not sure they end up being any better than a set of Konis and some swift springs. Personally if I had to choose I would go with good shocks and springs over the V3's. Longer wear and less up front.

Sounds like you are fairly serious at going to the track, if that's the case you really want to explore your options on a suspension purchase and do your homework. Going straight to a coilover 2 way adjustable damper is going to be an enormous change-and it's a substantial purchase. I am a bit in the same boat myself, after 2 months of reading everything I can- I still can't decide.

What part of cali are you in? There are a few guys here that can tell you much much more about it than I can, but it is no minor thing to go from OEM suspension to 2 way adjustable coils. That being said, the KW's are a well tuned "one size fits all" product that I am sure you would be happy with. Do some research first though.

cant compare the V3s to a koni and swfit spring combo. The KW dampers have alot of control being a double adjustable that actually works unlike alot of dampers out there. Thing is most people dont know how to or when to adjust the compression and rebound settings for optimum performance on track or comfort on the street.

Cossie, I wonder if any 370z in the US actually runs pss10. Are you thinking getting a used set from the 350 crowd then modify to fit? Can't see that to be a cheap option revalved + refit.

Good luck!

cossie1600

My ideal situation would be getting a set of used pss10 and have it revolved. Unfortnately there aren't many used ones for cheap for me to rebuild.

What sway bars are you looking to add?

Cv129, they sell them new, so I assume that is different than the 350 ones? I just saw they are a little bit more than the kW, might be worth the extra cash. I also know u can rebuild the bilsteins, I haven't heard the same about kW

I am leaning toward hotchkis

I asked on here awhile back about the PSS10's. Nobody here has them. Was told the S2000 crowd love them. The cheapest I found them for was about $2,500. Right now, I'm undecided on which coil-overs to get.

Once I get my SPL arms and bushing done in the front. I'm thinking about getting the Hotchkiss bar in the front too.

Yea they sell them new, I considered them once myself (bought something else on a good deal instead). I was referring to the idea of buying them used then revalved would be difficult, since almost no 370z runs them.

For KW, like takjak mentioned earlier, it may be worth to give Robi of Robispec a call, see if he valves V3. He ran a set on his own track 370z back in 09 or 10 (some ppl say its V3, some say it's clubsport version, I don't know), and he's very well known in the Evo community. Used V3 pop up here and there, used + revalve may still be cheaper than brand new V3.

cossie1600

I saw a set of v3 for 1200, was tempted except I want to find a place that can rebuild them first
