Second Hand BMW i3 Anti Roll Bar

The BMW i3 is unusual in that it uses a rear-wheel-drive layout with a fully independent suspension setup, and BMW engineered it without a conventional front anti roll bar in order to reduce unsprung weight and improve the ride comfort suited to its electric drivetrain. A rear anti roll bar is also not a standard fitment on the i3. If you are experiencing handling or suspension problems, the part you may actually be looking for is a control arm, trailing arm, or suspension link rather than an anti roll bar.

It is quite possible there has been a mix-up, as the BMW i3 was not fitted with anti roll bars in the conventional sense used on most passenger cars. It would be worth going back to the breaker and double-checking exactly which suspension component they are referring to, as the i3's suspension uses specific lateral and trailing links that sometimes get described loosely. Asking them to confirm the part against your registration number is the safest approach before ordering anything.

The BMW i3 received a facelift and range update from around 2017, which brought changes including a larger battery option (the 94Ah/33kWh pack) alongside the original 60Ah/22kWh pack, and some suspension component revisions came with these updates. Because the i3 does not use a conventional anti roll bar, if you are sourcing other suspension links or arms it is worth telling the breaker whether you have the pre-2017 or post-2017 car and confirming the part matches your specific build. Never assume a pre-facelift suspension part will interchange directly with a post-facelift car without the breaker checking against your registration.

Trim levels on the BMW i3, such as Suite, Lodge, or Loft, relate to interior specification and do not affect the suspension setup or the components used. The key factors for sourcing the correct suspension parts are the model year, battery pack variant, and whether the car has the optional range extender (REx) engine, as the extra weight of the REx unit can influence rear suspension loading. Always confirm the exact part with the breaker using your registration rather than relying on trim name alone.

Yes, this is worth flagging to the breaker, as the i3 REx carries an additional small petrol engine at the rear, adding meaningful weight over the rear axle compared to the pure battery-electric (BEV) version. This difference in rear loading means that some rear suspension components may differ or be subject to different wear rates between REx and BEV cars. Always tell the breaker which variant you have and ask them to confirm the part against your registration number to ensure compatibility.
