Suspension Secrets Front Offset Caster Bushes For BMW F20 M135i/M140i

Transform the performance of your BMW's front axle with our Suspension Secrets Front Offset Caster Bushes.

The standard bushes in the front lower control arms on the BMW F20 M135i/M140i are made from soft rubber. This rubber flexes when cornering, which leads to vagueness in the steering and understeer. The flexing of the rubber also contributes to instability when braking hard.

Our Suspension Secrets Front Offset Caster Bushes for the BMW F20 M135i/M140i fix both of issues whilst also improving suspension geometry too.

As our Suspension Secrets Front Offset Caster Bushes for the BMW F20 M135i/M140i are solid they do not flex like the original bushes, ensuring your steering remains accurate and communicative whilst also improving braking stability.

Our offset caster bushes also feature offset rose joints which increase positive caster, resulting in improved steering feel and more cornering grip thanks to the dynamic camber gain generated by caster.

We've also developed these bushes to help those BMW F20 M135i/M140i owners that already have caster-adjustable suspension top mounts fitted.

When running maximum caster, the front wheels can collide and rub against the wheel arch liners when turning, as they are no longer perfectly in the centre of the front wheel arch. Our caster bushes can be used to return the front wheels into the centre of the wheel arch, preventing them from rubbing against the wheel arch liners whilst not having to reduce positive caster on the suspension top mount.

The benefits of installing our Suspension Secrets Front Offset Caster Bushes for the BMW F20 M135i/M140i include: 

• Increased cornering grip and steering feel thanks to increased positive caster
• Improved braking stability and steering accuracy
• Enables complete control over suspension caster angle
• Allows you to run maximum camber on camber-adjustable top mounts without catching inner arch liner
