XYZ Racing Gravel Rally Coilovers — BMW 4 SERIES F83 M4 (Modified Rear Integrated) 2014-2020

The F83 M4 sends its power through the rear axle alone, and on tarmac that rear-wheel-drive layout is exactly what makes the car so exploitable through a corner. Take the same car onto a gravel stage and the story changes the moment the surface breaks away underneath it. XYZ Racing’s Gravel Rally coilover is built around that reality rather than around a smooth circuit lap.

This is the same range used across sandstone, snow and silt stage work, and for the 2014-2020 BMW 4 Series F83 M4 (Modified Rr Integrated) it swaps the factory’s tarmac-biased damping for a set-up built to keep the rear axle loaded and predictable when the road surface won’t stay still.

What this coilover does for your 2014-2020 Bmw 4 Series F83 M4 (Modified Rr Integrated)

Long-travel damping and long springs are the two specs that matter most here, because a gravel stage throws far more vertical wheel movement at the car than any tarmac corner does. Where the standard suspension on an F83 M4 is set up to control body movement on a smooth surface, this kit is built to absorb chassis vibration and repeated high-speed impacts from a rutted, bouncy road without the wheel losing contact with the ground. The inverted tube design adds resistance to the side loading a rear-wheel-drive car generates when the back end steps out under power on loose ground, and the spring rates are set to keep the M4 planted through the extreme G-force of a fast rally corner rather than pattering over every stone. The net effect on your car is a rear axle that stays connected to the road when the surface underneath it won’t.

About the Gravel Rally coilover

XYZ Racing built the Gravel Rally coilover specifically for rally and rallycross use, where the road surface is more punishing than in almost any other motorsport discipline. The damper uses an inverted tube design so one unit can be set up to cope with sandstone, snow or silt without the shaft losing support under side load. Stroke length and spring length are both extended well beyond a typical circuit set-up, which is what lets the damper soak up chassis vibration from a high-speed, bouncy stage road and still hold the car together through the extreme G-force of a fast direction change. XYZ Racing’s own rally team tested every spring rate in the range on actual stage events, so the settings come from competition data rather than a bench test.
