Cusco’s 21mm rear sway bar for the BP9 Legacy GT is a direct-fit replacement that also fits V6 naturally aspirated models where specified. Designed for BP9 Legacy applications, this rear stabilizer increases roll resistance to reduce body lean and improve handling balance. It installs using the vehicle’s stock attachment points, making it a straightforward upgrade for correcting rear-end roll characteristics.
