Riaction GT-1 Coilovers – 15-21 Subaru WRX / WRX STI (VA) | 32-Way Adjustable | RIA-VASTISS

Stock ride height leaves your WRX looking like it's on tiptoes.

The Riaction GT-1 coilovers give the 2015-2021 WRX and WRX STI a real suspension upgrade. They're monotube coilovers with 32 levels of damping adjustment and full-length ride height adjustment that doesn't change spring preload, so you set the height and the damping separately. The front pillowball top mounts add camber adjustment.

The damper body is a seamless 52mm electroplated carbon steel tube with a 44mm CNC-machined 6061 aluminum high-flow piston. The piston rod is 20mm up front and 14mm in the rear. The springs are SAE9254 cold-wound linear springs at 8K front and 8K rear. Multi-thickness valving shims, polyurethane oil seals, 7.5W suspension fluid, and a low-gas-pressure design round it out, and the whole kit is fully rebuildable.

These are lowering coilovers, so they won't raise the car or return it to the factory ride height.

But this isn't just about the drop.

It's about a WRX that sits right, turns in sharper, and lets you tune the setup for how you actually drive, whether it's a daily, a canyon car, or a weekend build.
