Tein Flex Z opinion

Going down on rate means the spring will bind. Going up on rate means being permanently underdamped (which isn't necessarily a bad thing).

Care to elaborate on the last bit?

Kinda makes me wanna see about going a bit heavier, maybe like a 7k or 8k spring.

You can, but I dont think 8k would work at all. 7k will likely be pretty bouncy.

Current spring is what?

6k - they feel under damped and boucy unless close to full stiff, my take anyway.

Agreed. I did 3 clicks for my track day, down from 5 for daily. It would be nice to utilize more clicks without being a boat.

They certainly feel bouncy at anything over 5 clicks from full stiff IMO

So I had an alignment done. But these things still feel super floaty. Is it possible there is not enough pre load on the springs? I am 5 clicks back from full stiff as well. I defs notice it at around 60mph that the car feels kinda light and lifty. I am a little less than 1/4 from full drop as well.

How do these Tein Flex Z coilovers compare to the RSR Sports I coilovers?

I realize that they're in a different price category, but I'm curious to compare them since I was originally looking at the RSR for their "streetability". I'm probably never going to track my car, and may autocross it for giggles once or twice a year. I'm really more interested in comfort and "sporty" driving on the street.

As I understand it, the Sports I uses the stock front mounts, where the Flex uses a pillow ball mount in front? Won't this cause a bit more harshness in the ride?

Anyway, thanks for your input all.

Surprisingly, these will ride smoother, even though in theory they shouldn't.

And performance-wise - how do they compare? I mean price and comfort-wise, Tein seem to be the winner, but will I be giving up a lot of "performance" when compared to the SportsI set? (I doubt I'm anywhere near fast enough to matter). LOL

Hi anyone, I have these installed here in Europe and my REAR camber is insane, I have to fix it somehow. What is the best option? Arms (and which), top hats? I am +-1.5" lower, 7/17" wheels.

you'll need LCAs to adjust the rear camber. my alignment shop recommends SPL (i have cusco). I just had these installed last week and i'm about 1.25 lower than stock. my rear camber is 1.75°.

First of I am a new member but have been lurking reading about the z flex opinion thread and from the opinions of the users here I was piqued enough to purchase a set.

I just wanted to get other users opinions about the coilover with regards to a loose knocking sound that seems to be coming from the upper mount.

I am in the Philippines and our roads are somewhat notorious for uneven payment and potholes. In saying that when I first installed the set it was done by a local dealership and I was present during the installation with instructions on hand. The set was not purchased through them and was imported through the local distributor the problem being he doesn't have a shop who could have done the installation. Anyhow, we set the height, damping and tried to follow everything to the t on the instructions except torque down the pillow ball nut. During my first test drive immediately upon hitting some uneven pavement there were loose sounds coming from the front coilovers. Its the type of sound that I would normally associate with a loose bolt somewhere and have heard it before on a car with worn out suspension bushings. There is definitely play in the system.

So after several days of searching on the web i came across several instances of the pillow nut not being torqued down enough. I went back to the shop had the suspension pulled down retorqued the pillow nut to 45lbs.ft or as stated in the instructions manual. Cant remember the exact figure and true enough things quieted down enough and the car ran beautifully. Until two days ago where in the driver side started up again.

The question is: do I have to keep torquing this nut as part of maintenance every two days? Or is there possibly a product defect?

One of the things I am thinking of doing is taking down the front coil overs again, undoing the pillow nuts applying some thread locker then torquing it down once again to the right spec.

Any assistance from the group would be great as Ive had no luck with the local distributor (his recommendation is keep running it as it may just be settling in and after a month if its still there he will file a warranty claim) and Ive emailed japan but have still not heard back from them. Possibly because my email was in English.
