Suspension Secrets Front Offset Caster Bushes - BMW F20 M135i/M140i - DRW Performance

Transform the performance of your BMW's front axle with the 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.

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

As these 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.

The 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.

Suspension Secrets 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. These 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.
