ISR Performance Pro Series Coilovers - Scion FR-S Subaru BRZ

The ISR Performance Pro Series Coilovers are 32-way adjustable mono-tube coilovers for the Scion FR-S and Subaru BRZ. 8k front spring rate, 6k rear spring rate, front pillowball upper camber mounts, and Japanese-sourced bearings. The upgrade tier from ISR's HR Basic coilover line - same chassis tuning philosophy with higher-end damper internals.

What It Does

Adjustable coilovers let you tune ride height and damping to the way you actually drive. 32 clicks of damping adjustment cover the range from a comfortable street setting to a stiff track setting. The mono-tube damper design dissipates heat better than twin-tube alternatives, which matters on a track-driven car where sustained suspension cycling builds heat in the dampers.

Front pillowball upper camber mounts give precise steering response and let you dial in camber for more aggressive alignment setups, which the FR-S / BRZ chassis benefits from significantly on track.

HR Basic vs Pro Series

ISR's HR Basic coilovers were the entry-level option that ISR also ran on their Formula D drift cars - proven on a professional drift platform. The Pro Series is the upgrade tier from HR Basic, with better damper internals and finer damping control. If you're building a serious street/track car and want more refined ride and handling than the HR Basic, the Pro Series is the next step up.
