Factory sway bars are tuned soft for comfort. Dinan's tubular set replaces both bars with larger, stiffer ones, so the car stays flatter through a corner and the tires keep more grip.
What you get
- 28 mm front bar, larger than the factory bar.
- 19 mm rear bar with two-hole adjustment.
- Tubular high-strength alloy steel to keep weight down.
- Polyurethane bushings and grease included.
Good to know
- For rear-wheel-drive M240i (G42), M340i (G20) and M440i (G22/G23/G26). xDrive cars need Dinan's xDrive set (D120-0635).
- The subframe has to be dropped to fit these, so professional installation is highly recommended. Dinan quotes 9.5 hours including an alignment.
