Developed to provide a sporty ride feeling and aggressive stance, along with wide-range damping force adjustment using our new Advance Needle technology, giving the driver a much more noticeable feel in damping force change. The shortened shell case design provides optimum damper stroke at lower than standard vehicle ride height. Vehicle ride height is adjustable via the ZT coated threaded sleeve. Updated internal components and external coatings increase durability and product life. Street Advance dampers are great for daily driving and spirited driving for all types of drivers. Made in Japan under strict quality control standards and developed by highly trained suspension engineers.

Good For The Price
Solid suspension and a great replacement for an aging stock setup. The coil overs are really stiff when put at their highest setting but soften a little bit when lowered. Great quality. The only problem I had is the main shaft spins when you try to tighten them onto the strut mount so its difficult to get them fully snugged to the mount.

Decent Product.
The product looks amazing, if you know about coilovers then you know the features are great. The installation is another story. If I were to purchase some more I would go with the Flex Z.

Street Advance Z
Product looks of good quality too soon to tell. Instructions not so clear. I am impressed with the ride quality, actually too soft in softest mode and a nice hard firm ride in the hard mode. Not sure how this is going to work on the track but will find out soon.

Good Coilovers
I've been running these coilovers pretty hard over the past few months and they have been absolutely amazing.

Easy to Install and Look Awesome
These coilovers are amazing. Dropped my car pretty low and made corning a lot smoother, durable design. I've had them on my car for well over a year and no issues. Adjustable to your liking.

Good Product
Bought this for my 2004 Subaru Impreza and it fitted nice. Only problem I had was tightening the top bolt because the shaft of the strut kept spinning, making it take a while to get nice a tightened. Other than that an amazing kit!

Fit Perfectly
About the easiest Instalation I've done that wasn't a Quick Strut. Much better than the 27 year old OEM shocks I had on before.

Tein 370Z Flex Z
Awesome! These coilovers made my Z nimble and feel 800lbs lighter. The stance is, at a glance, high performance.
