Second Hand BMW 1 Series Suspension Leg

A suspension leg (also called a MacPherson strut) combines the damper and the top mounting into a single front suspension unit, and yes, the BMW 1 Series does use suspension legs at the front on all variants across all generations. The rear suspension on the 1 Series is a multi-link setup rather than strut-based, so when buyers refer to a suspension leg they almost always mean the front nearside (NS) or offside (OS) unit. Make sure you specify which side you need when requesting a quote from a breaker.

These two cars sit in different generations: the first-generation E87/E81/E82/E88 ran from 2004 to 2011, while the second-generation F20/F21 launched in 2011. A 2007 car is E-series and a 2013 car is F-series, and the front suspension geometry and strut dimensions differ significantly between them, so they are not interchangeable. You should only be sourcing an F20/F21 suspension leg for a 2013 car, and a breaker can confirm the exact part reference against your registration.

For suspension legs, trim level itself does not determine fitment in the way that engine size or generation does, so an SE and an M Sport on the same generation and with the same engine are likely to share the same basic strut assembly. However, M Sport and Sport models on the 1 Series may have different spring or damper rates, and if a used strut comes complete with its spring it could carry different spring specifications to your original — confirm with the breaker whether the unit you are buying is a matched pair of strut and spring and whether it came from a sport-suspended car, particularly if your car has standard suspension.

Engine size can influence front suspension components on the 1 Series because heavier or more powerful engines may be accompanied by uprated strut specifications from the factory. Within the F20/F21 generation (2011 onwards), a 116i and a 135i are both using MacPherson front struts but the specifications may differ, so it is worth telling the breaker your engine code and not just the model year. This is especially relevant if you are sourcing a complete leg including the spring, as spring rates are matched to vehicle weight and power.

The second-generation F20/F21 1 Series received a facelift in 2015, bringing styling and equipment changes but the fundamental front suspension architecture remained MacPherson struts throughout the generation's life (2011 to 2019). In most cases the suspension leg itself will be compatible across the pre- and post-facelift F20/F21, but because mid-generation running gear revisions can sometimes occur alongside a facelift, you should ask the breaker to check the part against your specific registration rather than assuming any F20/F21 unit will suit a 2015 car without verification.

Both a 2017 and a 2019 1 Series fall within the F20/F21 second generation, which ran from 2011 through to 2019 when the third-generation F40 took over, so they are broadly the same platform. Fitment is likely but not guaranteed, as late production changes or engine-specific differences could affect strut specifications, and you should always give the breaker your full registration number so they can cross-reference the exact part needed for your car.
