XYZ Racing Street Advanced Coilovers — BMW 5 SERIES G31 (OE FOR REAR AIR STRUT) 2017-2026

The G31 Touring is the awkward one. BMW gave the saloon a passive rear setup and reserved factory air suspension for the estate’s self-levelling rear axle – which sounds clever until a bag fails out of warranty and the quote lands somewhere north of two grand per corner. The Street Advanced coilover is XYZ’s answer for owners who would rather convert the car to a conventional spring-and-damper rear than feed the air system forever.

For a long-wheelbase G31 carrying 1,800kg-plus of executive estate, this is the kit that lets you keep the car composed without committing to a track-focused setup. Ride height, damping and corner balance become things you control, not things the chassis decides for you.

What this coilover does for your 2017-2026 Bmw 5 Series G31 (OE for rear air strut)

Replacing the rear air struts with a sprung coilover gives you a car that finally feels of-a-piece, front to rear. The factory air system masks body movement well at cruise but goes soft and lazy when you load the chassis through a long sweeper – the Street Advanced removes that disconnect and lets the rear axle work with the front. With 720 damping positions across the range, you can soften everything off for motorway miles with the family aboard and tighten it back up for a Sunday on better roads, all from the top of the damper. Ride height is yours to set: drop the visual gap over the rear arches without the nose-up rake the OE airbags develop as they age, or sit the car level under load. The other quiet benefit is reliability – a conventional coilover removes the air compressor, lines and bags from your future-repair list entirely.

About the Street Advanced coilover

Street Advanced is XYZ’s most popular series and the one developed specifically for road cars that see the occasional track day rather than the other way around. The 720-way damping adjustment is the headline number – a single knob per corner moves through the rebound and compression curve in fine increments, which matters on a heavy estate where a click too far in either direction is the difference between settled and brittle. Construction is monotube with adjustable lower mounts, so ride height is set independently of spring preload – you keep full damper stroke regardless of how low you sit the car. The series has been refined over years of XYZ’s race programme and then re-tuned for street use, which is why it lands where it does: firmer and more capable than an OE-replacement strut, less single-minded than a circuit-only kit.

Fitment for the Bmw 5 Series G31 (OE for rear air strut) (2017-2026)

This kit fits the G31 Touring chassis (2017-2026) that left the factory with the rear air suspension option and converts it to a conventional coil-over-damper setup at the rear. Both front struts and rear units are supplied as a four-corner set. Confirm your car has the rear air strut configuration before ordering – the standard-suspension G31 takes a different part number.
