Hard launches and quick transitions show up worn dampers on a WRX fast, with the nose pitching and the rear stepping around on broken pavement. The Bilstein B6 Strut & Shock Set for the WRX uses Bilstein's B6 Performance dampers, monotube front and rear,, tuned for factory ride height and the stock springs. It fits 2015-2021 models, STI included, and contains both front strut assemblies and two rear shocks. Steering response sharpens and the car settles faster over mid-corner bumps, which helps on cold Calgary mornings when tires have less grip. It is a damper upgrade that keeps the car at its original stance. Canada-wide delivery, duties included, from Flat 4 Offroad in Calgary.
