Did they say why it was more , shocks are a serviceable item and should be replaced periodically , do they charge more after AN OIL CHANGE HA HA >??Going to add my experience with @CRS Performance . Went for the Koni kit. Now under 2m in height, way better ride and comfort, and looks the part now too. Held off adding my review until I’d driven it loaded. Totally worth the money - just wish I could have afforded it sooner. Better late than never.
Two tips to others - wheel alignment necessary afterwards and +£100pa more on insurance.
