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

The F83 M4’s cabriolet body carries more mass and less structural rigidity than the coupe it shares its S55 twin-turbo six with, and BMW’s factory adaptive dampers were tuned to hide that extra flex rather than sharpen the chassis underneath it. XYZ Racing’s Street Advanced coilover kit for the 2014-2020 BMW 4 Series F83 M4 (Modified Rr Integrated) swaps that factory compromise for independently adjustable ride height and 720-way damping control, front and rear, so the car can be set soft for the commute and wound up before it sees a circuit.

Street Advanced is the enthusiast-street spec in the XYZ Racing range: full ride-height and damping adjustment aimed at drivers who want their F83 to feel sharper on a B-road without losing the comfort needed for daily use. On a chassis that already puts well over 400bhp through the rear axle, controlling squat and body roll matters as much as ride quality, and this kit lets you set both yourself rather than accept one factory compromise.

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

Lowering and stiffening the F83 through a coilover with 720 damping positions means you’re not locked into one setting for the whole car. Wind the front end down and firm up compression to cut the nose-dive this heavy convertible shows under braking, then back the rear off for a supple ride when you’re not pushing on. The rear multi-link axle on the Modified Rr Integrated fitment benefits particularly from the added control, since it’s the part of the chassis doing the most work putting S55 torque down out of a corner. Ride height adjustment independent of spring preload also lets you correct the nose-up stance the factory setup leaves once the roof mechanism and extra bracing add weight over the front axle.

About the Street Advanced coilover

XYZ Racing built Street Advanced as its most widely fitted coilover, developed over several years of in-house testing and refined further through use in racing programmes worldwide, feedback that fed directly into the damper valving. It’s positioned for owners who split their time between normal road use and the occasional track day, rather than a car that lives exclusively on one or the other. The headline spec is 720 damping adjustment positions, giving a wide enough range to move meaningfully between a comfort-biased road setting and a firmer track setting without the shock running out of usable travel at either end. Construction follows XYZ’s standard coilover format, with separate ride-height and preload adjustment so corner weight can be set correctly on the BMW 4 Series once the kit is fitted. It’s built as everyday equipment for drivers who want genuine control over how the car sits and rides, not a track-only shock that’s uncomfortable the rest of the week.
