BMW F20 F21 xDrive M135i M140i 28mm Front 2-Way + 20mm Rear H&R Anti-Roll Bar Kit

H&R’s 28mm front (2-way adjustable) and 20mm rear anti-roll bar kit is engineered specifically for F20/F21 xDrive 6-cylinder models - including M135i and M140i. No guesswork: it bolts straight on to Typ 1K2/1K4 chassis.

• Front bar lets you dial in understeer or oversteer response - ideal for fast-road balance or track-day fine-tuning
• Rear bar is non-adjustable, matched to xDrive’s torque-split for predictable 4WD handling
• TÜV/ABE approved, German-made, and built to outlast softer aftermarket alternatives
• Works with stock or uprated suspension - no spacers, brackets or compromises needed
