Eibach E40-20-031-03-11 BMW Anti-Roll Bars

Transform your BMW’s handling with the Eibach Anti-Roll-Kit E40-20-031-03-11. These performance stabiliser bars, also known as anti roll bars or sway bars, are the go-to upgrade for BMW M2, M3 and M4 owners looking to reduce body roll, sharpen turn-in and increase cornering grip on fast road and track days. Engineered by Eibach from cold-formed steel alloy and finished in a durable red powder coat, this front and rear anti roll bar kit provides precise, confidence-inspiring handling without compromising day-to-day comfort.

Why choose the Eibach Anti-Roll-Kit for your BMW

• Reduce body roll for flatter, more controlled cornering
• Improve front-end bite and mid-corner stability for faster, cleaner exits
• Fine-tune handling balance to dial out understeer or oversteer
• Retains original spring characteristics during straight-line bumps for ride comfort
• Manufactured from cold-formed steel alloy for precision and consistent performance
• Long-lasting red powder coat finish resists corrosion
• Complete kit supplied with mounting hardware for a straightforward install

We have fitted and used these Eibach anti roll bars on customer cars and our own builds. Feedback is consistently positive: noticeably flatter cornering, more grip and a more connected, on-rails feel. A proven suspension upgrade for fast road and track use.
