XYZ Racing Top Sport Coilovers — BMW 4 SERIES G26 (2WD/4WD) 4/6CYL (Modified Rear Integrated) 2020-2026

The G26 Gran Coupe carries more weight over a longer wheelbase than the two-door 4 Series it shares a platform with, and that extra mass has to travel through a rear integral-link axle that was tuned by BMW for comfort rather than composure on a fast B-road. This XYZ Racing Top Sport coilover for the 4 Series G26 – covering both 2WD and xDrive cars across the four- and six-cylinder range – uses a rear kit built specifically around that integral-link layout, which is what the "Modified Rr Integrated" designation on this fitment refers to, rather than a generic multi-link adaptor.

Top Sport sits at the firmer end of XYZ’s road-legal line-up: a spec for owners who book the odd track day but still want the car civil on the drive home. It is not the daily-comfort option and it is not a full race kit – it is the middle ground built for a G26 that gets driven hard some weekends and normally the rest of the time.

What this coilover does for your 2020-2026 Bmw 4 Series

Damping is raised 30-50% over XYZ’s street-spec settings, and spring rates step up by around 2kg/mm, so the G26’s body stays flatter through direction changes instead of loading up slowly and pushing wide at the front. That stiffer response matters on a car this long and heavy – it keeps the contact patch working rather than skating over ridges and expansion joints, which shows up as sharper turn-in and less of the float you get from the factory rear axle under hard cornering. The same increase in damping control also suppresses the shock body movement that causes a big hit – a pothole, a kerb strike, a bad camber change mid-corner – to unsettle the rear on the integral-link cars. The net result on the road is a G26 that changes direction with more confidence and holds its line under power out of a bend, whether you’re in a four-cylinder 420i-spec car or a six-cylinder xDrive.

About the Top Sport coilover

XYZ built the Top Sport range from its own track-day and race experience rather than porting over comfort-biased street settings, and it shows in how the damping and spring rates are calibrated. Compared with the street-spec kits, damping force is increased by 30-50% or spring rate is stepped up by roughly 2kg/mm, depending on the platform – enough to control body movement under load without turning every expansion joint into a jolt through the cabin. The goal, in XYZ’s own terms, is to absorb the impact of rough tarmac and larger bumps while keeping the tyre’s contact patch loaded and the car stable, rather than letting the chassis wallow after a hit. It is pitched squarely at track day use and at speed on the road, where a driver wants the car to hold its composure lap after session rather than soften off after the first big compression.
