02-07 Subaru WRX GR50PRO

The Flatout Suspension GR50 is our flagship competition coilover system, built for the most demanding forms of motorsport — including stage rally, rallycross, and mixed-surface racing. Designed around massive 50mm inverted dampers housed in 62mm threaded bodies, the GR50 delivers exceptional strength, rigidity, and durability under extreme race conditions. The oversized design also increases oil capacity for more consistent performance during long, punishing events.

With adjustable rebound damping and external reservoirs, the GR50 gives drivers precise control and fade-resistant performance on tarmac, gravel, and dirt.
