Honestly I'll have to see if I can find the manual now. You can e-mail tein and they should be able to e-mail you english manual that has the measurements in it.

I have e-mailed them but have yet to receive an answer...

Which manual are you looking for?

All of the recommended settings are also on Tein USA's website.

Cant find the recommended spring preload

Only recommended heights. Would love to see the installation manual.

I would like to know how much spring preload Tein recommends to run at most, as I intend to run them high up (approx -10mm) and want to know how much bump travel I can get out of them without the springs slamming the damper in the extension stops when the wheel unloads. Thanks

The recommended preload is none (minimum; only enough to prevent play)

Ouch. Thanks. Nothing mentioned on "allowable" preload? A typical KW variant can run as much as 30mm preload (in their highest setting), how much would you dare running on the Flex A? I drive forest back roads with the occasional asphalt rooted up... need some more than ~35mm total bump travel with zero preload... 15mm? makes ~50mm and quite a difference...

Thanks.

(Love the idea of the HBS but not in the market for a full blown Group N suspension obviously.)

Based on what I know, I would say 20mm is safe. I wouldn't go higher than that unless you have a very clear idea of what you're doing.

Excellent feedback! Can @Racecomp Engineering contribute in with a second opinion? Now running the yellows and they make the most out of the stock dampers, but those dreaded bumpstops...

I don't have any first hand experience with these Teins. I'll say for your uses travel and good valving are crucial. A dual height adjustable coilover has the advantage for lower drops, but for taller ride heights, a single height adjustable coilover will generally get you more bump travel in comparison.

Edit:
Probably not gonna work, see below...

Thanks both. I think I'll try the Flex A and [s]hope to be able to run them with ~15mm preload. Should give decent bump travel approx halfway the shock travel, no traditional bumpstop action and as a small upside to somewhat limited bump travel, better ground clearance at full compression. [/s]

Alternative would be Bilstein B8 and custom (6k) springs (or B6 with helper) but don't like the lack of adjustability in case I get it wrong... next owner will probably prefer coilovers also...

Did some more homework just to be sure, checked spring free length, damper stroke and counted approx. 5,5 coils on the front spring. Assuming a wire diameter of 10mm, there is no room left for preload, or the coils will all bind. Probably what happened with Shady 195 as quoted below.

Car doesn't feel any different handling wise but it no longer bottoms out.

Too bad, but again confirms, no good idea to run a suspension outside its design point (sure the manual recommended spring preload??)

vividracing · 10-15-2015, 02:07 PM

Just got off the phone with Tein USA. They recommend 2mm of preload on the Z and adjust the ride height via the lower mount.

I would never by again Tein Flex Z for spirited tarmac rally style driving.
Like my grandma said "buying cheap is expensive" ( because you will be unhappy and buy something else)

I have play a lot with setting now
the best I found but still far from perfect is:

Rear:
10 mm drop, 8 mm preload and 5 click from full stiff ( Euro Tein Flex stiffer than US)
Front
15 mm drop, 5 mm preload and 7 click from full stiff ( Euro Tein Flex stiffer than US)

With this setup I found back the playful feeling of the OEM GT86, I don't scrap anymore the bottom of the car on B road, and I run less on the bumpstop.
I think it's mostly due to go back to a set up with higher rear like Oem compare to even like Tein manual say. The even set up make it feel like a dead car maybe great for track or show car but you loose all the fun on the B road.

So that setup is less sexy than the lower Tien set up but it's so much more efficient for B road. And anyway when I seat behind my steering wheel I don't see if my car is sexy I just feel if the driving is exiting. I don't set my car for other to look at it I set it up too get Fun efficient drive. Any way I have also RPF1 in 17x8 because they are light but how ugly are those wheel. Ugliest I never got on car but they do their job

I bought this car because I wanted a fun playful car, were i get lot of feedback and excitement at lower speed to avoid ending in prison because I'm way way to fast on B road. The OEM setup with OEM spring was doing that perfectly give me a big smile and feeling so fast at much slower speed compare to my other car. My other car is audi RS2 with lot of power and torque set up to have maximum grip R888 tyre, KW V3, Big Roll bar...... With that car I can be crazy fast on B road but anything slower than crazy fast I mean really crazy fast is so boring because that car have so much grip and absorbe bump and hole so easy. So I bought the GT86 to get this level of excitement at much much lower speed and OEM it did what it promise still well in 3 digit in some of the straight but it's a really fun slow car. I thought that I would get the same kind of enhancement with those Flex Z on B road that with the KW V3 but that is very far from it so only plus of those is how smooth it drive at low speed on small bump like small tarmac junction.... My wife said it much more confortable in town but she said she get out of her Chair on B road.
So if you look fore sexy look and confortable city driving and some track day's on smooth track go for the Tein Flex if you are in to fast B road save your money for something matching better your expectation.
