hi everyone, i am new to this forum. i got my silverstone z last month and i love it. i am planning to get some coilovers for my z. i had a hard time to decide what to get!! help!!
which one will be the best for daily driving, but on weekends, you know....i'm gonna have fun!

1) Tein Flex
2) Nismo S-tune
3) JIC
4) others

thanks for any input!!

 

From what I've read and heard all three setups are great. Raceboy did an excellent writeup on the Nismo setup a couple weeks ago which you should really check out. John350z runs the JIC and absoluely loves them- but they are the most expensive of the three and as VQ mentions the stiffest of the bunch.
I personally went with the Tein setup for a couple of reasons-
1. height adjustment- everyone says "yea but how much are you honestly going to adjust them?" To be honest, not very often. But I wanted the ability to initially adjust the suspension to the height of my liking. I didn't want to be "stuck" with a certain drop and end up not liking it.
2. Dampening adjustment- The EDFC was a major reason in choosing the Tein Flex setup- ability to adjust the dampening w/o popping the hood and the trunk (or w/o having to stop the car)
I was very close to purchasing the Nismo set up and decided against it purley because of the height adjustment- Check out Raceboy's write up and PM me if you have specific questions on the Tein setup.

Hope this helps and good luck.

thanks a lot man!! thanks too VQ!!

 

The JIC has a little softer front spring than the Tein coilovers, and I believe the JIC has a 45mm piston as opposed to the 40mm Tein piston. I've decided that I'm going to go with the JIC setup since I track my car pretty often and the Tein setup is more of a street setup.

 

JIC are also a mono tube whereas the Teins are a dual- basically as the dampeners get a work out the duals tend to get tiny air bubbles in the fluid- this leads to a very slightly less responsive feeling. You are going to feel the road a bit better with the JIC setup under heavy cornering.

 

Can anyone outline the exact technical differences between the JIC and Teins?

 

Make -- kg/mm (F/R) -- lbs/in (F/R)

JIC -- 10/12 -- 564/674
Tein -- 10/10 -- 559/550

Interesting, I could have sworn the Teins were previously listed as 12kg/mm front and rear... (search for past threads on this subject).

Does anyone know about the difference in the materials used? For instance, do the JICs weigh less? Do they in fact have a larger piston?

 

Just found this...

 

useful information, please check PM

 

Failsaf3, are you happy with your choice of the Teins? Have they performed as you had hoped? Thanks.

 

I love the Tein setup. The only down side is that they exhibit some minor noise (can be heard with the windows up).

 

Specifically,

The JIC FLT-A2 is a monotube damper as mentioned above while the Tein are a twin tube damper. The monotube damper does not need to compress as much as a twin tube damper to move the same amount of fluid. This translates into better response. Not only that but the monotube will not generate heat as a twin tube would. Monotubes do hold a higher gass pressure than twin tubes. The monotube coilover won't make the pshtt pshtt sound that you hear in pretty much all aftermarket twin tubes.

This is one of the primary reasons the JIC is more expensive. I wouldn't doubt that the JIC's are lighter than the tein. I'm sure the casings are of differring materials.

IMO, the Tein is wayyyy over priced for a twin tube setup. Granted it's perks are a more comfortable ride and the EDFC. Both the JIC's and the Flex allow you to lower the vehicle without sacrificing suspension travel or ride quality. That's key for a twin tube damper that doesn't have the shorter stroke of the monotube.

I hope this helped a little. I like the fact that JIC can rebuild and is willing to change out dampers per my request in the event that the functions change for my car. I got a place that will do them for 1700 shipped to me for the JIC's. I think that's about the same price the Flex's go for. So for me, less for more didn't work. More for same sounded better. lol. The teins were like just a tad more expensive, around 1715 or something.

 

Something's not making it in the translation. Lowered vehicles have less suspension travel. Unless your using drop spindel's. Stiffer spring's do effect ride quality. How odd that you'd mention the jic's in the same breath of their not effecting ride quality. The jic's stand out via owner report's as having the harshest ride quality of any lowering system offered thus far. Followed by the tein's. I'll take a harsh ride quality,........if it delivers.

I'm all for the handling improvement's these systems offer, but labeling them as not sacrificing suspension travel or ride quality just isn't responsible. I'm hoping you ment something else, but given what you said, well
