BMW M3 M4 Service Guide

BMW’s Motorsport’s division has been churning out some of the most exciting sports sedans and coupes since the E28 M5 debuted in 1985. However, the world really took notice when BMW homologated their M3 racecar for the road. Since then, there have been 5 generations of M3 sedans and coupes, with the current one being the F80 generation M3 sedan and M4 Coupe. Introduced in 2014, this was the first time the M3 name was applied to the sedan only, with the M4 moniker distinguishing the coupe.

This BMW M3/M4 Service Guide is intended as a guideline to owners, or perhaps potential owners, in what and when scheduled maintenance is recommended. Following this maintenance schedule will prevent any costly repairs or mechanical failures that can happen due if neglected.

Alignment can seriously affect both tire wear as well as the handling characteristics of a car. Therefore, it is imperative that the alignment is checked on a regular basis. The BMW M3/M4 Service Guide recommends checking camber, castor, and toe for tolerances within factory specification, or a custom specification if deemed necessary.

The suspension’s job is to not only keep a comfortable ride, it is also to provide optimal handling characteristics. Properly functioning suspension will keep alignment within specification in a straight line as well as in the corners. Moreover, this keeps the tires from wearing unevenly. At each service interval, it is recommended to check the suspension components for any squeaks, rattles, leakage, or play.
