Suspension Secrets BMW F20/F21 M140i & F22/F23 M240i Adjustable Camber & Caster Plates

Enhance the front-end precision and adaptability of your BMW with the Suspension Secrets Adjustable Camber & Caster Plates, developed for the F20/F21 M140i and F22/F23 M240i. Designed for enthusiasts and track-day drivers alike, these high-performance top mounts allow independent adjustment of both camber and caster, giving you the freedom to fine-tune your suspension geometry for superior turn-in, sharper handling, and increased front-end grip.

Unlock True Geometry Control

The factory front top mounts on the F2X chassis offer no adjustment for camber or caster, severely limiting your ability to tailor the handling characteristics of your BMW. The Suspension Secrets Adjustable Camber & Caster Plates solve this issue by offering full independent adjustment of both alignment parameters without the need for any chassis modifications. This means you can dial in aggressive geometry settings for track use while maintaining comfort and control for the road.

Engineered for Precision and Durability

Crafted from aerospace-grade aluminium and hard anodised for durability, these top mounts are built to endure the harshest driving conditions. They feature motorsport-specification spherical bearings that eliminate unwanted flex or deflection, maintaining precise suspension movement and improving steering response. The high-quality design ensures minimal NVH (noise, vibration, and harshness), making them suitable for fast road setups as well as track-prepared builds.

Independent Camber & Caster Adjustment

These camber and caster plates provide a wide range of adjustment without affecting spring position or requiring any other suspension components to be altered. Caster adjustment improves high-speed stability and enhances steering feel, while camber adjustment increases cornering grip by optimising tyre contact with the road surface. Together, they offer a significant improvement in front-end confidence and responsiveness.

Key Features & Benefits

• Independent Camber & Caster Adjustment – Optimise geometry for fast road or track use.
• Precise Steering Feel – Improved caster results in enhanced stability and sharper turn-in.

Ideal for Modified and Performance-Oriented BMWs

Whether you’ve fitted upgraded suspension or are looking to maximise the capability of your factory setup, these adjustable camber and caster plates are essential for achieving a properly dialled-in front end. Perfect for use with coilovers, lowering springs, and uprated dampers, they give you full control over how your car handles in different conditions and environments.
