H&R Anti-Roll/Sway Bar Stabiliser/Stabilizer Kit for BMW M135i M235i M Performance (F21 F22 F2x, N55) – Front 28mm 2-Position Adjustable, Rear 20mm – ARB Roll Bar Suspension Handling Upgrade for 1 Series & 2 Series

H&R Roll-Control Stabiliser Set for BMW F21 F22 M135i M235i - Front 28 mm 2-position, Rear 20 mm

Unlock razor-sharp handling and confidence-inspiring stability on road and track with this H&R front and rear roll-control package for the BMW 1 Series and 2 Series N55 models. By increasing roll stiffness with precision-engineered bars, your car corners flatter, responds faster to steering inputs and maintains a more neutral balance so you can drive harder with greater control.

Why this chassis upgrade is a game changer

• Flatter cornering - cuts body lean for a bigger tyre contact patch and more mechanical grip
• Crisper turn-in - improved response for rapid direction changes and B-road confidence
• Balanced dynamics - dial out push at the front and tidy up the rear for a stable, neutral feel
• Tuneable front rate - 2-position front bar lets you fine-tune your setup for road or track
• Everyday comfort retained - complements OE dampers, springs and most sport suspension
