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

The BM-BN Mazda 3 arrived with a chassis that punched well above its hatchback billing – Skyactiv weight savings, a quick rack, and a front end that actually wants to turn in. What it never got from the factory was damping that could hold the body still when you start asking real questions of it on a B-road or a circuit. The stock struts run out of control over mid-corner bumps and the nose dives hard under braking, blunting everything the chassis is otherwise willing to do.

The XYZ Racing Racing Spec coilover is the answer for owners who’ve outgrown lowering springs and want a setup built for committed driving on a 2014-2018 Mazda 3. This is the firmest, most circuit-focused kit in the XYZ range, and on the BM-BN it transforms the car from a willing hatch into something with proper body control.

What this coilover does for your 2014-2018 Mazda 3

Damping comes via a 30-step adjuster on each unit, so the front and rear can be tuned independently to balance the BM-BN’s natural front-bias. Wind the fronts up a couple of clicks to kill the dive under brakes, leave the rears softer, and the car starts rotating on trail-brake the way the chassis always promised. Ride height is set on the lower mount rather than by spring preload, so you can drop the car for stance without sacrificing usable shock stroke – important on a hatch that has to live with UK speed bumps. Pillowball top mounts at the front sharpen steering response and remove the rubbery on-centre lag the stock top hats introduce. Spring rates are stiffer than the Super Sport, so this is a kit that earns its keep when you’re driving hard rather than commuting.

About the Racing Spec coilover

The Racing Spec sits at the top of XYZ’s road-and-track ladder. Construction is full monotube, larger-diameter piston than the entry kits, with separated rebound and compression characteristics tuned to handle higher spring rates without going harsh on initial bump. Bodies are CNC-machined aluminium where possible to keep unsprung mass down, and the threaded section is hard-anodised to survive UK winters. Each kit ships pre-assembled with linear-rate springs matched to the BM-BN’s corner weights and the application’s intended use – circuit work, time attack, and serious fast-road. The 30-way adjuster meters both bump and rebound from a single knob, so set-up changes between sessions stay simple.

Fitment for the Mazda 3 (BM-BN) (2014-2018)

This kit is specified for the BM and BN-chassis Mazda 3 built from 2014 through 2018, covering both five-door hatch and saloon variants on the standard Skyactiv strut-and-multilink layout. Front struts and rear shock-and-spring assemblies are supplied as a four-corner kit; no modification to the OE top mounts or subframes is required.
