If your tracking the flex series over ther ST's. I'm really impressed with the ride.

If you ask me I'd say spend the extra money and grab the Flex A.

I have the Flex Z, but if I could go back and I'd buy the Flex A. My area is having a shit load of construction going on this past year and these pot holes, bumps, uneven roads are just real......And seeing that you said you have bad roads just justifies me telling you to grab the Tein Flex A.
I don't know if you're going to be tracking, but if you're not, you can't go wrong with the Flex A.


I'm not saying the Flex Z is uncomfortable at all, it's very comfortable and actually rides almost exactly like stock if not a little better. I'm only lowered just an inch. I never driven or had Flex A but I'm sure it's probably A LOT more comfortable than the Flex Z.


TL DR: Spend the extra money and buy the Flex A

What are differences in csg spec and regular flex A?

Valving to handle harder duty, useful if you're canyoning or tracking.

I have Flex A on 2017 GT86 (UK version). I went for 18x9.5 wheels with MPS4 tyres and somewhat lower (about 2.5 inch I recon).

Some roads here absolutely horrible, pothole after pothole and speed bumps every 150m or so.

8 or 9 from full hard (out of 16) feels better than stock on daily driving and noticeably better over speeding bumps. Its a little wobbly at times but less so than my other car (Lexus).

On track 2 or 3 from hard is much better, although somewhat harsh over curbs. 4 is more comfortable, but I ended up thinking that 3 may be the perfect balance.

Adjustments are easy.

whats the difference between Tein street flex and the csg flex A? Saw them on your site, Is the A worth the extra $$? Is the flex A worth it over the Bilstein B14 set?

Very different.

CSG Spec FLA is very different from TEIN Flex A, TEIN Street Flex, Bilstein B14, etc. You get a very refined ride quality with solid performance while providing sufficient longevity, a quality that is very difficult to achieve while seeking greater levels of performance, valving refinement, and budget consciousness.

CSG Spec damper valving development started with the TEIN SRC 2-Way, which was then pushed into the TEIN Street Flex to see if a 1-way setup was even feasible. Long story short, many years of development was fit into the CSG Flex A while also test proven for performance and longevity on both early model (zenki) and late model (kouki) ZC6/ZN6 chassis.

so, essentially, its the B14 at the bottom, then the street flex, and the better of the three will be the CSG flexA? I'm not in the market for a set yet but I will be later on. I'd like to keep about the same as stock feel/comfort even after lowering it without having to worry about bumpstops and too short of a stroke.

B14 and Street Flex were pretty popular back in 2012 and 2013, but as improvements were made with the platform, so has many aftermarket components. With the new 2017, we were able to finalize some testing with the CSG FLA and are releasing units soon. 1st batch is in the US now and going through quality control/customs. 2nd batch will be arriving next month.

In terms of lowering issues, we tested throughout the entire height adjustment range with no other suspension modifications and setups with complete suspension replacement. Validation of this level is something that we are proud of and can say that the CSG FLA will work with a variety of setups going from complete OEM to fully modified suspension components. :)

Will you be offering FLA packages that include camber plates?

It includes camber plates already.

Don’t forget about MeisterR,s. Decent bang for the buck as well.

How about pure daily driving only. No track. No autox.
Tein flex z?

Stay stock. Maybe a lowering spring.
