Eibach E40-20-031-02-11 BMW Anti-Roll Bars - Anti-Roll-Kit Performance Stabiliser Bars for BMW 1 Series, 2 Series, 3 Series, 4 Series
Transform the handling of your BMW with the Eibach Anti-Roll-Kit. This front and rear anti-roll bar kit is the go-to BMW sway bar upgrade for sharper turn-in, reduced body roll and flatter cornering on fast road and track. If you are searching for BMW anti roll bars, BMW stabiliser bars or BMW sway bars for F20, F21, F22, F23, F30, F31, F34, F32, F33, F36 platforms, this Eibach kit delivers proven performance, precision and durability.
We run these bars on our own builds and our customers consistently report tighter body control, improved balance and increased confidence through high-speed direction changes. Pair with Eibach Pro-Kit or Sportline springs for the complete BMW suspension upgrade, or fit on standard springs to dramatically cut roll without changing ride height.
Why choose the Eibach Anti-Roll-Kit for your BMW
- Reduces body roll for flatter, faster cornering and razor-sharp turn-in
- Enhances front and rear grip and stability in real-world fast road and track driving
- Refines balance to help dial out excess understeer or oversteer
- Keeps original ride height and preserves primary spring characteristics
- Cold-formed steel for precision performance and long-term strength
- Durable red powder coat finish to resist corrosion
- Supplied complete with mounting hardware for a quality, straightforward install
What the Eibach Anti-Roll-Kit does
By increasing roll stiffness versus OEM bars, the kit transfers cornering load more evenly across the axle, reducing the load difference between inner and outer wheels. The centre of gravity effectively recentres during cornering, which improves tyre contact, traction and steering precision. During equal suspension movement the bars stay neutral, so ride comfort and the core character of your springs remain unchanged.
