XYZ Racing Super Sport Coilovers — Mazda 3 (BM-BN) (Modified Rear Integrated) 2014-2018

The BM-BN Mazda 3 arrived with a chassis that was already sharper than most hot hatches in its segment – SkyActiv lightweight construction, a quick rack, and a front end that turned in with genuine intent. What it didn’t get from the factory was damping that could keep up with that geometry once owners started chasing kerbs or threading a B-road at pace. The XYZ Racing Super Sport coilover for the 2014-2018 Mazda 3 BM-BN is the fast-road kit that addresses exactly that shortfall.

Super Sport is XYZ’s road-biased platform, built around the same monotube hardware as the track kits but valved for surfaces that have actual texture to them. For a daily-driven BM or BN – whether it’s a naturally aspirated 2.0 SkyActiv-G hatch or the heavier 2.2 SkyActiv-D saloon – it tightens body control without making the cabin a punishment for everyone inside.

What this coilover does for your 2014-2018 Mazda 3

The Mazda 3 BM-BN carries most of its mass over the front axle, and on standard dampers it leans on its outside-front tyre under load, scrubbing speed and washing the nose wide. Dropping it onto the Super Sport recovers the cornering attitude the chassis is geometrically capable of: less roll, a flatter platform under trail-braking, and a rear axle that stays settled instead of skipping over mid-corner ruts. Ride height is adjustable independently of spring preload, so you can sit the car where it looks right without binding the dampers or sacrificing travel. The 30-way damping adjustment lets you run the car softer for the commute and firmer for a weekend blast without touching the springs, and pillowball top mounts on the fronts sharpen turn-in noticeably from the moment the steering loads up.

About the Super Sport coilover

Super Sport uses a full-length adjustable monotube damper with a large-bore piston, separating ride-height adjustment from spring preload so you can corner-weight the car properly. The springs are linear-rate, matched to the BM-BN’s kerb weight and front-biased balance rather than pulled from a generic chart. Damping is adjusted via a single 30-position knob that influences both bump and rebound on a calibrated curve, which makes setup faster for owners who don’t want to wrestle with separate high and low-speed circuits. Spring seats and lock collars are machined from aluminium for corrosion resistance on UK winter roads, and the bodies are hard-anodised. It’s the kit XYZ pitches as the right answer when the buyer wants the car lower, tauter and more communicative on the road, with enough headroom to handle the occasional track day without re-valving.

Fitment for the Mazda 3 (2014-2018)

This kit fits the BM and BN generation Mazda 3, covering the 2014 through 2018 production span in both five-door hatchback and four-door saloon bodies. It is engineered for the standard front strut and rear multi-link layout used across the SkyActiv-G petrol and SkyActiv-D diesel variants of this chassis.
