BMW M3 G80 / M4 G82 Suspension Secrets Kinematics Kit

Suspension Secrets Full Kinematics Kit for BMW G80 M3 and G82 M4. Complete Chassis Kinematics Upgrade for Maximum Track Performance and Suspension Control.

The BMW G80 M3 and G82 M4 represent one of the most advanced modern performance platforms, combining the S58 twin-turbo engine with a highly capable chassis designed to perform across both road and circuit environments.

While previous upgrades such as the Suspension Secrets Handling Packs focus on improving and refining suspension geometry, the factory chassis architecture still retains significant limitations when the vehicle is pushed into sustained high-load track use. Compliance in the suspension bushings, limited rear axle control, and factory kinematic constraints all begin to affect consistency, predictability, and precision when operating at a high level.

The Suspension Secrets Full Kinematics Kit is a complete chassis transformation package designed specifically for track-focused G8X builds. This is not a simple geometry upgrade — it replaces key suspension pivot points and control elements to fundamentally alter how the suspension behaves under load.

This kit combines adjustable rear toe arms, rear camber arms, rear traction arms, solid rear control arm bushes, and solid front offset caster bushes, delivering a complete rear axle and front geometry control system for full track conversion use.

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

Key Features

• Full chassis kinematics upgrade for BMW G80 M3 & G82 M4
• Complete rear axle geometry and compliance overhaul
• Improved high-load cornering stability
• Increased suspension precision under braking and acceleration
• Reduced chassis flex and unwanted compliance
• Enhanced alignment stability under track conditions
• Improved tyre consistency and feedback
• Motorsport-grade UK-manufactured components
• Designed for dedicated track and competition use

What this Kit Delivers

The Full Kinematics Kit transforms the rear axle and key front suspension characteristics of the G80 and G82 platform, significantly reducing unwanted compliance and improving alignment stability under load. The result is a chassis that maintains geometry more consistently through cornering, braking, and acceleration phases, delivering a more predictable and repeatable handling platform for track use. This leads to improved driver confidence, more consistent tyre behaviour, and a more controlled balance at the limit of grip.

Full Chassis Kinematics Development

The Full Kinematics Kit sits above the entire Handling Pack range and represents the final stage of Suspension Secrets’ G8X chassis development system.

Where Handling Pack 1 focuses on fast-road optimisation, Handling Pack 2 introduces Clubsport-level control, and Handling Pack 3 delivers track-focused geometry refinement, the Full Kinematics Kit goes further by addressing the fundamental movement and compliance of the suspension itself.

By upgrading both geometry adjustment and suspension pivot characteristics, this kit allows the G8X chassis to operate with far greater precision under sustained cornering, braking, and acceleration loads.

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 G80 (2021+)
• BMW M4 G82 (2021+)

This kinematics package may be suitable for other M-Powered cars in the G8X 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.
