Bilstein B14 PSS Coilover Kit — WRX / STI (2015–2021)
Verified fit
2015–2021 Subaru WRX · 2015–2021 Subaru WRX STI
Description
Bilstein B14 PSS is the right coilover for a WRX owner who wants height adjustment + a noticeable damping upgrade over OE, doesn't want to mess with click adjustments, and is keeping the car as a daily.
Fixed damping (no adjustment), monotube, gas-pressurized. Ride height drops 30–50 mm. TÜV-tested for road use in EU markets — meaningful here because it means Bilstein actually durability-tested the spring/damper combo at road speed.
