XYZ Racing Gravel Rally Coilovers — BMW 5 SERIES G61 i5 (OE FOR REAR AIR STROT) 2024-2026

The G61 i5 wasn’t built for loose surfaces. It was built to glide German autobahns on rear air struts, with two-and-a-half tonnes of battery, motor and luxury saloon mass riding on bushings tuned for refinement. Convert that car to a gravel stage weapon and the OE rear air setup becomes the single biggest problem on the build sheet – which is exactly the conversion these XYZ Racing Gravel Rally coilovers are designed to solve.

This is a rally-spec damper kit engineered specifically for the G61 i5 chassis with factory rear air suspension, replacing the air struts at the back with conventional spring-over-damper hardware and matching the front with a long-stroke inverted setup. It’s a niche fitment for a niche use, and the kit reflects that.

What this coilover does for your 2024-2026 Bmw 5 Series G61 i5 (OE FOR REAR AIR STROT)

You get suspension travel the road car never had, full stop. The long-stroke inverted front damper and long spring at the rear let the heavy G61 platform soak up step-edges, water bars and sandstone braking zones without bottoming or pitching onto the bump stops. Spring rates have been set against rally team feedback rather than guessed, so the i5’s weight distribution is accounted for from the start – the front end stays composed under trail braking on shale, and the rear keeps the inside wheel loaded through cambered turns. Rebound control across high-speed bouncy sections is the headline gain; you can attack a fast, broken straight without the chassis going light over crests. The inverted tube layout also keeps the damper’s working section above the road debris that will otherwise eat conventional shocks alive on a stage.

About the Gravel Rally coilover

The Gravel Rally is XYZ Racing’s dedicated loose-surface damper, developed for rally and rallycross use where the surface itself – sandstone, snow, silt – is the variable. It uses an inverted tube construction, which puts the larger-diameter, more rigid section closest to the wheel and protects the damper rod from stone strikes and side-load deflection. Stroke length is extended well beyond fast-road or circuit specs to handle the vertical input of jumps, compressions and broken cambers, and the springs are physically longer to keep the assembly loaded through full droop. Spring rates across the range have been validated by rally racing teams in competition, not on a dyno bench. Within the Cool Bear UK range this is the most specialised damper in the catalogue, sitting well outside the Top Sport / Super Sport circuit-and-road line-up.

Fitment for the Bmw 5 Series (2024-2026)

This kit fits the G61 i5 estate chassis from 2024 through 2026, chassis reference BM132, and is built specifically for cars with the factory rear air strut suspension – the rear strut layout in this kit replaces those air units with conventional springs. Confirm your build sheet shows rear air before ordering.
