I love them!

The Tein Flex Z Coilover kit was a great addition to my car. On the recommended settings the dampening feels great on the street and handles much better than stock. The more agressive settings are nice and firm for the track. The installation was straight forward and it was nice that they could be bolted right in without having to assemble and set starting ride height.

Big improvement

Great product! I didn’t really use rally’s awesome customer service because everything went smoothly. My 13 wrx hatch is ridding a lot better now. I’ve been running them for about 1500 miles on my daily driver with really only minor issues. Upon install make sure you have all torque specs needed. Some forums out there have the wrong specs so be careful. Also I kinda wish I would have put a spacer on top of the high hats in the back, due to a rattling between the high hat and it’s bed I had to crank the back nuts down hard to stop bad rattle. The instructions that come with it are great but hard to understand you will definitely want a metric tape measure and I had to take it to a shop after for alinement. It’s so solid now even with stock sway bars. Thanks RSD!

Flex Z on 13 WRX
Rick D 11 months ago
These coilovers have been great so far performance wise. On the 8 setting the car is stiffer and rides smoother than stock if that makes sense. At closer to 0 setting the car is rock solid and handles like on rails. Down to 12-16 rides very smooth. Love these coils! The only issue i have is a clunking noise from the rear right coil. I have removed and re-installed to no resolution. Working with TEIN support who seems to be slow in their response time... Will update on how that pans out. Hard to give these a 4 star though because they perform great.

Good for daily drive

I installed this on my GH impreza non-turbo, since it's the same chasis as GH wrx, the coilovers fits perfectly. I had to find the correct ride height and damping settings to be able to use in our very rough road here our country. I had to ditch my eibach swaybars front and rear to make the ride easier for daily drive, overall the car feels very planted on the road and comfortable..

Hey there, I have the exact same car as was thinking about doing the exact same thing. I currently have sway bars installed. You ARE recommending removing the bars and just using the coilovers? Any added danger to not having the bar on the front? I know out model originally didnt have one in the back .

hello, I removed my eibach swaybars, and installed the stock bars, mine has both front and rear. when my eibach bars are installed, cars handle very well.. but my wife found it uncomfortable.. the car is daily drive, and here in our country, the roads are exceptionally bad. if you live in a place with not so good roads, better stay with stock swaybars if you want to install these coils. hope it helps

I've been running these on my 09 WRX for a couple weeks now and I absolutely love them. They really make the car feel planted and they've improved the feel of the car immensely. My car is really low and I do scrape everywhere but that's my fault. They're a great bang for your buck.

  • Q: OEM Strut Mounts  StreetSolutions 2 years ago


    Would be possible to use them with the OEM Strut Mounts?

    • A: This kit will have aftermarket mounts included in the coilover. If you are wanting a kit that does not have aftermarket mounts, I would recommend the Tein Street Basis Coilovers, which are designed to be used with your OEM Strut Mounts.

    How do these compare to the BC BR Series coilovers?

    • A: These are very comparable to BC's BR Coilovers! These will offer a softer spring rate and have twin tube damper. Whereas the BC's have a stiffer spring rate and monotube damper.
