Tein Flex Z Coilovers – 2015-2021 Subaru WRX / STI (VA) | VSSB2-C1SA4-C

Dial it in. Set it low. Let the VA do the talking.
The Tein Flex Z is the move for WRX owners who want real Japanese coilovers without paying for a race program they'll never use. Built in Yokohama, Japan, this is the same Tein quality the scene has trusted for decades, made for a street car that still wants to get after it.
Full-length height adjustment means you set your stance without killing your stroke or messing with spring preload. 16 levels of damping let you go soft for the daily or firm it up for canyon runs, all from one knob per corner. Twin-tube, gas-charged dampers keep the ride composed, and the sealed construction keeps them tight for the long haul. Want to adjust damping from the driver's seat? It's EDFC compatible.
But this isn't just about lowering your car.
It's about that first pull out of the garage when the fender gap is gone and the car finally sits right. It's the planted feel through the on-ramp, the way the chassis settles into a corner instead of leaning on it. Your WRX was built with potential. This is how you unlock it, without beating yourself up on every expansion joint.
