XYZ Racing Gravel Rally Coilovers — Honda CIVIC FB (Modified Rear lntegrated) 2012-2015

The Civic FB was built as a front-drive family saloon, not a stage car, and its standard torsion-beam rear axle was never meant to soak up washboard gravel at speed. This kit pairs the front struts with the Modified Rr lntegrated rear conversion, giving the FB a true coilover mounting point at the back axle instead of the stock beam’s fixed geometry, so both ends of the car can actually be tuned for loose-surface work.

That matters because gravel punishes a chassis in a completely different way to tarmac. Compression events arrive faster and harder, the surface changes metre to metre, and a road-biased damper will pack down and skate long before a stage ends. The Gravel Rally spec is XYZ Racing’s answer to that specific problem, built for the FB rather than adapted from a track-day part.

What this coilover does for your 2012-2015 Honda CIVIC FB (Modified Rr lntegrated)

Fit this kit and the FB stops feeling like a car coping with rough ground and starts feeling like one designed for it. The long-stroke damper and matched long spring give the suspension far more travel to work with before the chassis bottoms out over a compression or a rutted crest, which on the FB’s torsion-beam-derived platform is where standard setups run out of ideas first. The Modified Rr lntegrated rear conversion lets that extra travel do something useful at the back axle too, instead of the rear staying tied to its factory beam geometry while only the front improves. Spring rates carried over from Rally Racing team testing are set up to control body movement under the repeated, high-frequency hits of a gravel stage rather than the smoother loads of a circuit, so the car settles faster between impacts and holds its line through braking zones on loose surfaces where grip is already limited.

About the Gravel Rally coilover

XYZ Racing built the Gravel Rally coilover specifically for rally and rallycross use, where the surface underneath the car is the most aggressive a damper will ever face – sandstone, packed snow, loose silt, sometimes all in the same event. The inverted tube construction puts the larger diameter tube at the top of the damper body, which keeps the working shaft better shielded from the debris a gravel stage throws up and helps the unit keep working consistently as conditions shift run to run. Long stroke travel combined with a long, matched spring gives the damper room to absorb chassis vibration and the repeated, aggressive hits that come from attacking a bumpy, high-speed road surface, rather than relying on stiffness alone to hold the car up. That same setup is built to cope with the extreme G-forces generated under hard cornering on loose surfaces, where the tyre’s available grip changes constantly and the damper has to manage load transfer without unsettling the car. XYZ Racing’s Rally Racing team tested and set the spring rates on this unit directly, so the baseline is drawn from stage running rather than a road-car compromise.

Fitment for the Honda CIVIC FB (Modified Rr lntegrated) (2012-2015)

This kit is specified for the Honda CIVIC FB in Modified Rr lntegrated configuration across the 2012 to 2015 model years, chassis code HN25-3. The Modified Rr lntegrated designation covers the rear-end conversion required for this platform, so the coilover’s rear mounting is matched to that layout rather than the standard torsion-beam setup.
