Performance suspension for BMW 1 Series.
This complete handling package is built to fix the floaty, disconnected rear end that so many 1 Series owners talk about and to sharpen steering response for confident, precise driving. Whether you daily a 118d or run a stage 3 M140i, this is a proven, high-impact suspension upgrade that makes your BMW 1 Series feel tighter, more stable and more predictable. We run this setup on our own car and customers consistently tell us it is night and day better.
Rear subframe insert options
Choose the insert stiffness that suits your driving:
- Yellow subframe inserts – softer compound for street use, excellent comfort with a big step up in rear-end stability.
- Black subframe inserts – harder compound for maximum stiffness and track focus. This is what we run on our own car for the most connected rear end.
The result is a tighter, less floaty rear that inspires confidence in fast corners and on uneven roads.
Bilstein coilover choices – B12, B14 or B16
Bilstein coilovers are some of the best in the game for a BMW 1 Series handling kit. Pick the setup that matches your goals:
- Bilstein B12 – matched spring and damper kit supplied at Bilstein’s recommended ride height. Plug-and-play simplicity with immediate control and comfort improvements.
- Bilstein B14 – height adjustable coilovers so you can fine-tune ride height to dial in stance and balance.
- Bilstein B16 – height and damping adjustable coilovers. Stiffen it up for the track, soften it for the drive home. The most versatile, premium choice for road and track.
Underbrace and M3/M4 control arms
These chassis upgrades complete the package and dramatically improve front-end bite and overall stability:
- Underbrace – BMW thought these cars had one, but many do not. Fitting one makes a big difference. It removes the vague, floaty feeling and ties the rear together for much sharper responses.
- M3/M4 front control arms – stiffer arms for a heavier, more direct steering feel, improved turn-in and an extra degree of camber to help front-end grip.
