Why this sway bar set is the go‑to upgrade

If you want your BMW to corner flatter, respond quicker and feel more composed without ruining ride quality, this H&R stabiliser kit delivers. By increasing roll stiffness you dramatically reduce lean in bends, tighten up steering response and unlock a more neutral balance. Understeer and oversteer are curtailed, mid‑corner grip improves and the car feels predictable and confidence inspiring on B‑roads, motorways and track days alike.

• Significant reduction in body movement through fast direction changes
• Faster, cleaner corner exits with improved traction
• Sharpened front end bite and more stable rear axle
• Two‑way adjustment lets you dial in street, fast road or circuit settings
• Engineered strength resists fatigue and helps prevent corrosion over time

Engineered to last

H&R design and build every component in their own German facility. Each bar is formed from a single piece of premium alloy steel, cold formed for superior surface finish and stress resistance, then heat treated for exceptional hardness and shape retention. Every kit is verified under strict TÜV standards for safety and quality.

Proven by us and our customers
