Delphi Suspension Track Bar P/N:TC3221
Keep the rear axle centered and located side-to-side with the Delphi Suspension Track Bar (TC6785). This rear track bar drops in as a direct-fit replacement for the listed applications: the 2011 BMW 1 SERIES M and the 2008-2012 BMW M3 — see the Buyer's Guide tab for engine-level fitment. The track bar anchors the rear axle to the chassis, resisting lateral movement so the axle stays centered under the body through cornering and over uneven pavement.
Delphi includes the necessary accessories for a complete job. If a worn or damaged rear track bar is the cause of loose rear-axle tracking or a rear end that feels like it wanders, this replaces it.
