Details

The Tein Flex Z is a product line that is evolved from the STREET FLEX SF damper kit system. Historically, FLEX kits from Tein are sets which are readily adapted to many uses, from street to track driving. For the STREET FLEX SF variant, Tein softed the damping levels and extended stroke range to make the damper kits more tractable for daily use. For many years, Tein product carried the banner of performance value by making damper tubes that could be torn down, overhauled, and re-valved.

As the market evolves with emerging entrants and an increasing need for value, Tein re-designed their popular STREET FLEX SF line and renamed it the FLEX Z. The "Z-line" moniker has been added to the Street Advance Z and Street Basis Z, and represents a damper tube with similar internal construction as the outgoing overhaul-available "non-Z" product, but a new outer tube which is sealed. Rather than rebuilding worn dampers, users now will simply purchase replacements.

Newer manufacturing techniques, as well as revised springs that do not need spring seat adapters, allow the new Z-line to come in at a lower MSRP. Tein has literally reset the typical value proposition for assembled full-length damper kit with the FLEX Z. Many users are surprised at the pricing that Flex Z dampers can be had at assuming they are a compromise in quality, or that they are now made in China rather than in Japan. Neither is correct as these parts are still made from scratch in-house by Tein Japan with much of the same internal components that have made Tein products reliable and refined solutions for street-sport applications.

Tein Flex Z offers many features highly valued by users including:

  • Twin-Tube System for Comfortable Ride on Streets
  • Full-Length System for Ride Height Adjustment w/ Minimal Change in Ride
  • Damping Force Adjustable to Change Ride to Desired Settings
  • Compatible with EDFC Series to enable In-Car Damping Force Adjustment
  • Upper Mounts Included for Easy Installation
  • Highly Durable & Reliable
  • Thoroughgoing Rust-Proofing
  • Smooth Ride Height Adjustment & One-of-A-Kind Adjusting Wrench
  • No-Sag Springs
  • High-Spec Damper Oil

Customer Questions

Q:

I was wondering if these would fit on a 07 Accord. I know a lot of TSX parts are interchangeable with the CM6 chassis and I was wondering if this was the case with these. Thanks!

A:

This Tein TSX kit could be adapted to a 7th generation accord fairly easily, yes. You just need some washers in the rear to fit them in the rear knuckles properly.

Q:What is the spring rate with the Flex Z set? I'm more into comfort now I've had stiff BC coilovers and K sports which I hated so I wanted to look at teins but was torn between street advance and flex Z set mainly because of included top hats also concerned about spring rate as well so which are better?
A:

The spring rate on this kit should be 12 front and 7 rear. These are not "soft" rates for the TSX, but are good "medium" rates. They will be compliant but sporting. The main plus with the Street Flex Z is the full-length adjustment which means that you can have more height options. If you are not looking to go more than about 2" down, the Street Advance is perfectly awesome! Although the springs are a bit softer with the SA/SAZ the ride will be more compliant. You aren't going to give up tons of performance either, so if you aren't tracking the car it should be a viable option. We're happy to give more direct consultation over the phone as well. 949-295-1668

Q:Will I be able to drop and tuck tires on these coils or are the bC coils my only option. Trying to achieve low functionally but don't want to sacrifice quality.
A:

This FLEX Z damper set should be good for a 3"-3.25" drop which certainly will tuck the tires a little (based on knowing that a 2" drop is enough to get a very tight finger gap at the fenders, an additional 1"-1.5" will definitely be tucking.

Q:Bought this set from you guys recently but haven't had a chance for install. Will be doing it next month. My question is, what damper settings should I adjust to if you could recommend for exclusive daily street use? I would be switching over from some tein comfort sports which worked wonders for me and were great in terms of comfort and ride quality but are way too soft for my liking due to the 7/4 spring rate. I even had both the front and rear dampers set almost full stiff.
A:

Thanks for reaching out! For our advice on turning your dampers, please read this posting and let us know if you need further advice: How to tune your adjustable coilover/damper kit for the street.
