BMW M3 G80 / M4 G82 Suspension Secrets Kinematics Kit

Suspension Secrets Full Kinematics Kit for BMW F80 M3 and F82 M4. Complete Chassis Kinematics Upgrade for Maximum Track Performance and Suspension Control.

The BMW F80 M3 and F82 M4 are highly capable performance platforms, offering strong chassis balance, responsive steering, and excellent tuning potential. However, even at the highest levels of modification, the factory suspension architecture still retains significant compliance and kinematic limitations designed for road comfort, durability, and mass-market usability.

While the Suspension Secrets Handling Packs progressively improve geometry, roll control, and chassis response, the Full Kinematics Kit represents a completely different level of chassis transformation. This is not an incremental upgrade — it is a full re-engineering of key suspension pivot points and compliance characteristics to fundamentally change how the car behaves under load.

Designed specifically for track-focused and competition-style builds, this package delivers maximum control over suspension geometry, articulation, and rear axle behaviour, creating a highly consistent and predictable chassis at the limit.

This kit replaces key factory suspension bushings and arms with fully adjustable and solid-mounted motorsport-grade components, significantly reducing compliance and allowing precise control of camber, toe, caster, and traction characteristics across all driving conditions.

This is designed for serious track or motorsport-oriented builds where maximum consistency, repeatability, and chassis control are the priority.

Key Features

• Full kinematics upgrade for BMW F80 M3 & F82 M4
• Highest level Suspension Secrets F8X chassis package
• Complete rear axle geometry and compliance overhaul
• Maximum adjustability for track alignment setup
• Improved suspension precision under high load
• Reduced unwanted chassis flex and movement
• Enhanced traction and stability under acceleration
• Improved braking stability and consistency
• Designed and manufactured in the UK for motorsport use

What this Kit Delivers

The Full Kinematics Kit delivers a fundamental transformation in how the rear axle and front suspension of the F8X platform behave under load. By replacing factory rubber bushings and fixed geometry components with adjustable and solid-mounted systems, the kit removes unwanted deflection and allows precise control of suspension movement throughout cornering, braking, and acceleration phases. The result is a chassis that remains stable and consistent even under repeated high-load conditions, delivering improved grip, better tyre utilisation, and significantly enhanced driver feedback at the limit.

• Suspension Secrets Adjustable Rear Toe Arms (including rear toe lockout kit)
• Suspension Secrets Adjustable Rear Camber Arms (including rear camber lockout kit)
• Suspension Secrets Adjustable Rear Traction Arms (Trailing Arm)
• Suspension Secrets Solid Rear Control Arm Bushes
• Suspension Secrets Solid Front Offset Caster Bushes

Full Chassis Kinematics Development

The Full Kinematics Kit sits above the entire Suspension Secrets Handling Pack range.

Where Handling Pack 1 improves fast-road geometry, Handling Pack 2 introduces Clubsport-level roll control, and Handling Pack 3 delivers a full track suspension and geometry package, the Full Kinematics Kit goes one step further by addressing the underlying suspension compliance and kinematic behaviour of the chassis itself.

This is the ultimate stage in the F8X suspension ecosystem and is intended for fully track-prepared or motorsport-oriented vehicles.

It is intended for fully track-prepared vehicles where OEM compliance is no longer required.

Why Suspension Secrets?

Suspension Secrets is a UK-based suspension and chassis dynamics specialist focused on precision-engineered solutions for high-performance road cars and motorsport applications.

Their development approach is based on real-world testing and geometry optimisation rather than generic adjustability. Each component is designed to improve grip, stability, and driver confidence while maintaining OEM-level durability.

All products are manufactured in the UK using billet aluminium, stainless steel hardware, and motorsport-grade spherical bearings.

Installation

Professional installation and a full alignment setup are strongly recommended to fully realise the benefits of this package. Correct geometry setup is essential to tailoring the chassis for road or track use.

If you choose to opt for Installation here at our HQ, this includes full installation of this pack alongside a full geometry setup which includes 4-wheel alignment and corner weighting (As long as you have a height-adjustable suspension setup). We will require the vehicle for a full day.

Compatibility:

• BMW M3 F80 (2014-2020)
• BMW M4 F82 (2014-2018)

This kinematics package may be suitable for other M-Powered cars in the F8X range so please get in touch for more information

Please Note:

• We are able to ship this kit world-wide
• As this is a motorsport derived kit it does not include instructions but rather needs to be installed by a technician with BMW and Motorsport experience. Incorrect setup post installation will result in deteriorated performance.
• If you are unsure of fitment, or would like up to date stock levels, please drop us a message and get in touch.
