Frequently Asked Questions

Find answers to common questions about torque specifications

What type of suspension system does the 2019-Present BMW M8 use?

The 2019-Present BMW M8 features an Adaptive M Suspension system with electronically controlled dampers. It includes a double-wishbone front axle and a five-link rear axle, optimized for high-performance handling and comfort. The system adjusts damping forces in real-time based on driving conditions and driver inputs.

What is the ride height of the BMW M8?

The standard ride height of the BMW M8 is approximately 138 mm (5.43 inches) at the front and 140 mm (5.51 inches) at the rear. This can vary slightly depending on the specific trim (e.g., M8 Competition) and optional configurations such as the M Carbon Package.

Can the suspension be manually adjusted?

Yes, the Adaptive M Suspension allows drivers to manually adjust the damping characteristics via the Driving Dynamics Control system. Options include Comfort, Sport, and Sport+ modes, each altering the suspension stiffness and responsiveness to suit driving preferences.

What is the spring rate of the BMW M8 suspension?

The front spring rate is approximately 28 N/mm, while the rear spring rate is around 32 N/mm. These rates are designed to balance high-performance cornering with ride comfort, and they may vary slightly depending on the model variant and optional equipment.

Does the BMW M8 have air suspension?

No, the BMW M8 does not feature air suspension. It utilizes a conventional coil spring setup with adaptive dampers, which are lighter and more responsive for high-performance driving.

What is the maximum wheel camber adjustment for the BMW M8?

The front wheels can be adjusted to a maximum negative camber of -1.5 degrees, while the rear wheels can be adjusted to -2.0 degrees. These settings are optimized for track performance and can be fine-tuned during professional alignment services.
