BMW i4 Coil Spring Replacement Parts

The BMW i4 uses conventional steel coil springs on all variants — it does not have air suspension as standard — so coil springs are a genuine used part worth sourcing from a breaker. The i4 was launched in 2021 as a G26-generation model, and all road-going variants use coil spring suspension front and rear. If you've been told it has adaptive suspension, that refers to the optional electronically controlled dampers, not air springs — the coil springs are still present alongside those dampers.

The BMW i4 is a G26-generation car that launched in 2021, and all current production falls within that same generation, so there is no generation boundary to worry about between a 2022 and 2024 car. That said, BMW introduced a mid-life update to the i4 in 2024, and whether any suspension changes accompanied that refresh is something you should confirm with the breaker against your specific registration before buying. Make sure you also specify the axle — front and rear springs are not interchangeable.

Trim level alone does not determine spring fitment, but the i4 M50 is a significantly heavier and more powerful all-wheel-drive variant compared to the eDrive35 or eDrive40, so its suspension components are likely to be different. Always source springs matched to the same powertrain type — RWD single-motor versus AWD twin-motor — rather than assuming any i4 spring is a universal fit. Confirm the exact specification with the breaker against your registration to be certain.

Yes — coil springs are side-specific on the BMW i4, so a nearside (NS, passenger side in the UK) spring is not interchangeable with an offside (OS, driver side) spring. When contacting a breaker, always state clearly which side you need, and also whether you need a front or rear spring, as these are different parts too. Getting the wrong side is a common and easily avoided mistake.

It's possible that cars fitted with BMW's optional adaptive (electronically controlled) damper package use springs with a different rate to those on cars with standard passive dampers, as manufacturers often pair specific springs to each damper setup. However, spring rate variants are something you should confirm directly with the breaker against your registration, rather than assume based on the option code alone. A good breaker will be able to cross-reference the donor vehicle's spec to make sure the spring matches your car's setup.

The BMW i4 shares its G26 platform with the 4 Series Gran Coupé, and some suspension components are carried across, but the i4 is heavier due to its battery pack and has different powertrain configurations, which can affect spring specification. Whether a spring from a combustion-engined G26 4 Series directly fits an i4 is something you must confirm with the breaker against both vehicles' registrations — do not assume platform sharing means the springs are identical. A reputable breaker will be able to check the part numbers before supplying.
