BMW 128i Sway Bar - Rear - Dinan - 15.8mm - '06-'13. This Dinan rear anti-roll bar reduces body roll and trims understeer for a more planted, confident BMW.

Engineered and tuned by Dinan for the E82/E90/E92/E93 chassis, the 15.8mm rear bar keeps the car flatter while preserving day-to-day drivability. Stiffness gains are significant versus common OE sizes: +118% vs 13mm, +23% vs 15mm, +201% vs 12mm, and +326% vs 11mm (application dependent). It can be added as you build a Stage 1 suspension. For proper balance on RWD cars, pair with the Dinan D120-0530 28mm front bar, especially with an LSD or rear tires 20mm wider than front. Not compatible with 328xi.
