The Tein Flex A Coilovers feature the new Hydraulic Bump Stopper which will provide a comfortable ride for all the passengers.When a lowered vehicle goes over large bumps, typically they will have a urethane or a rubber bump stops that absorb the shock. However the Tein Flex A is equipped with the Hydraulic Bump Stop which is mounted inside the shock absorber. This effectively generates the damping force near, or at full-bump to absorb large impacts in a smoother manner. This latest technology has been inspired, tested, and proven in World Rally Championships, and has been passed on to street driven vehicles.
These also feature independent ride height adjustment. Which means you can effectively change the ride height by adjusting the case length without messing with the pre-load. With this feature the change in ride quality is minimal when the height is adjusted. This is perfect for those of you who want to remain slammed, while having a comfortable ride. Top hats are included so you don’t have to re-use your stock units, or source out other upper mounts. They are compatible with EDFC Series to enable in-car dampening control, and come with adjusting tools. They are also available for overhauling.
In conclusion if you’re going to put a set of coilovers on your car, Tein is a household name that has been tested, proven, and found success in the likes of several motorsports genres. Get a set of proper coilovers for your car tat will improve both looks, and handling.

Hopefully whoever is reading this uses my review as they teetering point to buy these things. I spent hours looking for a nice pair of coils within my price range. Kept hearing day in and day out that "cheap coils" were crap. Not with these. I wanted the whole get up, good ride quality, great handling, and the ability to rebuild the coil. Something you cant't ask from all coils, especially cheap ones. However, This set up DOES have it all. Comes pre-loaded from factory. So if you have a stock 2015+ WRX or STI it rides pretty damn near perfect right out of the box. Even with the stock wheels. From what people are saying, I can confirm these ride so much smoother than the Flex A's. The $200 extra I say is worth it. The only cons to these coils was the extra road noise that was introduced. Factory top hats are all rubber but these are top hats are metal.
I was a little cautious buying coilovers for my 2015 Sti, but had saw these being praised for their comfort vs the flex Z’s. So far after a month, I have really had no real problems out of these coilovers at all. I left them the height they were from the factory and it gave roughly a 1.2” front and 1” rear drop. The install was fairly simple, and everything went together nicely. The only downer is that they do cause some noise over bumps, which I have been told is normal. I fixed the noise mostly by spraying some white lithium grease and it’s now good to go. I do still hear some sound from the shocks when they are absorbing bumps, but have been told that the noise is normal and to be expected. Overall though these coils are a great ride quality, and I would almost say that it’s a better ride quality than stock. I 100% recommend these for someone looking for a comfort.
I like them, very affordable coilovers. Make the ride much smoother. Might have to add some wd40 to get rid of noise when going over bumps
I bought these coilovers for my STI, ride quality is awesome, better then the factory ride to be honest. plus the guys at IIR know how tp keep you happy with that super fast shipping, overall I love the coils and couldn't be more happier
