Frequently Asked Questions

Find answers to common questions about torque specifications

What type of suspension does the 2016-2021 BMW M2 use?

The 2016-2021 BMW M2 features a double-joint spring strut front axle and a five-link rear axle. The suspension is tuned for high-performance driving, with adaptive M suspension available as an option, which includes electronically controlled dampers for dynamic handling adjustments.

What is the ride height of the BMW M2?

The standard ride height of the BMW M2 is approximately 140 mm (5.5 inches) at the front and 135 mm (5.3 inches) at the rear. This can vary slightly depending on the suspension package and optional adaptive M suspension.

Can the suspension be adjusted for track use?

Yes, the optional adaptive M suspension allows for adjustable damping settings, including Comfort, Sport, and Sport+ modes. For track use, Sport+ mode is recommended as it provides the stiffest damping for improved cornering stability and reduced body roll.

What are the torque specifications for suspension components?

The front strut mount bolts should be torqued to 81 Nm (60 lb-ft), while the rear axle carrier bolts require 100 Nm (74 lb-ft). Always refer to the official BMW repair manual for specific torque values and tightening sequences to ensure proper installation.

How often should the suspension components be inspected?

BMW recommends inspecting the suspension components every 20,000 miles or during routine maintenance. Pay special attention to bushings, ball joints, and shock absorbers for signs of wear or damage, especially if the vehicle is used for performance driving.
