The Bilstein B6 Performance front-right strut is a yellow monotube, gas-pressure replacement for the factory strut on rear-wheel-drive Subaru BRZ, Scion FR-S, and Toyota 86/GR86 chassis. The manufacturer describes the B6 as a bolt-on performance upgrade for stock suspension, tuned firmer than OE. Its digressive piston reacts to changing road conditions, and the monotube body provides consistent fade free performance.

Compared with a stock strut, the B6 is the choice for drivers who want steadier damping without a full coilover conversion. The manufacturer states that each B6 is calibrated to its specific vehicle rather than a generic setting. Bilstein's warranty for the B6 strut line is listed as a limited lifetime warranty, which matters when comparing against cheaper aftermarket struts. Track and autocross drivers searching for a BRZ or GR86 front strut upgrade that keeps daily ride quality will find this a practical middle ground.
Because this is a right-side unit, a pair needs the matching left-side strut. Installation is a strut-level swap: remove the complete strut and clamp it in an appropriate strut vise, then reassemble the mounting parts in reverse order. Keep rubber-mounted fasteners loose until the car is back on its wheels, as the rubber-mounted strut and damper attachments should not be fully tightened until the suspension is loaded.
The manufacturer's Canadian catalog lists 2013 – 2020 Subaru BRZ, 2017 Toyota 86, 2022 Subaru BRZ, and 2023 Toyota GR86. Other sources give wider or different year ranges, so confirm your exact year and drivetrain with the manufacturer before ordering.
The manufacturer positions the B6 as a bolt-on upgrade for stock suspension, so the strut is designed to work with the factory spring. Spring changes are a separate decision, and you should check the manufacturer's install guidance for any spring pairing.

This is a moderate-difficulty job for a home mechanic with a floor jack, jack stands, a torque wrench, and a set of sockets. If you reuse the factory spring, you will need a spring compressor to free the top mount. Disconnect the brake line clip, sway bar link, and knuckle fasteners before removing the strut. Mark the orientation of the upper mount and bearing so they go back the same way. After installation, have the front alignment checked, since strut replacement changes camber and toe settings.
