I was considering getting some used Teins and was just wondering if it would be worth it? They currently have around 10k miles on them. How long do they usually last for? and how much would be a fair price?

 

depends, how ruff the owner was with the system. i think they around 1g. brand new. you should do some searching.

 

Depends on which model, I haven't seen the history of retail's effected too much when EDFC is included.

Basic: $500-$600 ($400 is absolute lowest I recall ever seeing)
Flex: $900-$1100 ($800 is the lowest I recall ever seeing)
CS(T): same as flex
Monoflex: Not too many of these come up for sale $1200-$1400

In case it helps, here are specs for Tein 350Z coilovers

Go here to see min/max and recommended ride height's http://www.tein.com/price/nissan.html

Tein Flex (twin tube construction, adjustable dampners
Full-length adjustment and height adjustment for separate setting of the height and spring preload
Spring rates 672/672
Side Note: High spring rates mean even when the adjustable damping is set as low as possible, you may not find ride quality happiness, several reports of this setups harshness exist Yet a few owner comment’s of a “like stock ride quality” also exist. However given the fact that they use a spring stiffness that’s much stiffer then oem, if ride quality is a concern, either hitch a ride in a car equipped with them or make a different choice. In addition, several early review’s have been done by people actually having the original more softly sprung Tein Flex coilovers do not take their comments to mean the same as the one using the current product, the original product specs are listed below under Tein Flex JDM.

Tein Flex JDM specs (can be special ordered est 10-12 weeks delivery)
Full-length adjustment and height adjustment for separate setting of the height and spring preload
Spring rates 560/560
side Note: This is the original specs first offered in the U.S. with the Flex, shortly after it’s introduction the specs changed to those listed further above (672/672)

Tein MonoFlex Monotube, adjustable dampning M.S.V valving, full height adjustable
Spring rates 784/784
Side Note: Well reviewed on my350Z, but a greater level of caution should be exercised if you drive on "B" roads very often. Also, not a slam dunk vs other offerings in the same class.

Tein MonoFlex JDM same specs as above, but softer valving and spring rates
Spring rates 560/504

Tein Super Racing Monotube, external reservoir, adjustable with independent settings for compression and rebound, full height adjustable
Spring rates 895/895 (web site say's they don't come with springs)
Side note: Valving?, lack of overall resources, having one source to repair or revalve, and having several other choices in this class make this a tuff sell.

Tein Basic (twin tube construction, non adjustable dampners )
Spring rates 504/504
Side Note: Popular because of price and the brand name. Some say it has too much bounce, others like the setup just fine. Getting a ride in a owner equipped car before you buy, isn't a bad idea.

Tein SS JDM (twin tube construction, adjustable dampners )
(JDM only at this time. 10-12 weeks delivery, ocean transit unless you pay air freight)
Spring rates 392/392



Tein CS (Monotube constructionad, adjustable dampners )
Special Note: A comfort ride system compare to HKS III and Bilstein Pss10.They are valved and sprung to fulfill their intended mission of offering up improved ride comfort. More specifically their valving will impact the performance they can deliver. And to add, revalving them is extremely expensive if you find they are too soft for you. If you want performance, pick a different Tein offering or pick a different brand.
Spring rates 392/392
