XYZ Racing Circuit Master Coilovers — Honda CIVIC FB (Modified Rear lntegrated) 2012-2015

The FB-generation Civic’s torsion-beam rear was never built with adjustable damping in mind, which is why this Circuit Master kit is matched to a modified rear-integrated axle rather than the stock beam. That modification is what opens up genuine four-corner adjustment on a chassis that would otherwise leave you tuning the front end only. For a car that spends its life on circuit lap-time work rather than the school run, that difference decides whether the rear axle tracks through direction changes or just follows wherever the front sends it.

XYZ Racing built the Circuit Master around sustained track sessions rather than one hot lap and a cool-down. On a 2012-2015 Honda Civic FB running the Modified Rr lntegrated rear, that means a platform you can reset lap on lap rather than one that drifts as the dampers heat up.

What this coilover does for your 2012-2015 Honda Civic FB

With 9720 combinations of damping adjustment spread across 3 external knobs, you can set the front stiff enough to control nose-dive under trail braking into a hairpin, then back the modified rear-integrated axle off enough to keep it following the road surface instead of skipping over kerbs. That range matters on a front-driven chassis like the FB Civic, where understeer under power is the default failure mode – adding rebound at the rear corner helps rotate the car earlier on turn-in without unsettling it mid-corner. Ride height comes down too, which lowers the centre of gravity and tightens body roll through the Civic’s front strut geometry. Because every adjustment is external, you can make these changes trackside between sessions instead of pulling the car apart.

About the Circuit Master coilover

The Circuit Master is the damper XYZ Racing builds around sustained circuit lap-time work, developed and run by XYZ’s own racing teams on international circuits rather than put together for a fast-road brochure. It offers 9720 combinations of damping adjustment across 3 external knobs, giving you separate control over the damping circuit rather than one blunt setting for the whole range. Those knobs work through a fine, small-orifice oil passage, and that passage can produce a faint noise when a wheel crosses a sharp bump – a normal side effect of the fine-adjustment circuit, not a fault, and not something you’ll register once you’re carrying real speed on a track surface. Because the kit is built for repeated sessions rather than a single lap, the adjustment range exists so you can react to what the car does as track temperature and grip change through the day.

Fitment for the Honda Civic FB (2012-2015)

This kit is built for the Honda Civic FB, chassis code HN25-3, model years 2012 to 2015, specifically the Modified Rr lntegrated rear configuration. Confirm your Civic’s rear axle has already had this modification carried out before ordering, since the kit is matched to the modified mounting points rather than the factory torsion beam.
