XYZ Racing Top Sport Coilovers — Mazda 6 / ATENZA (GJ1-GL) 2012-2026

The GJ-generation Mazda 6 was designed around SkyActiv weight reduction and a long wheelbase, which gave it a composed motorway gait but left the standard dampers underdamped for spirited driving – body roll arrives early and the front tyres run out of camber long before grip. The XYZ Racing Top Sport coilover is the track-leaning answer for owners who want the GJ saloon or Tourer to behave like the chassis always promised on paper.

This is a circuit-biased kit aimed at trackday Mazda 6 drivers and fast-road owners who happily trade a little compliance for body control. The Top Sport sits at the sharper end of the XYZ range, sharing the same monotube architecture as the Circuit Master but tuned to keep the GJ flat through long, loaded corners.

What this coilover does for your 2012-2026 Mazda 6 / Atenza (GJ1-GL)

Drop the GJ onto the Top Sport and the first thing you notice is the nose finally taking a set on turn-in instead of washing wide on the outer front tyre. The 30-level damping adjustment lets you bring the rebound up to match the heavier petrol 2.5 or diesel 2.2 noses without making the rear skittish over mid-corner bumps. Ride height adjustment is independent of spring preload, so you can lower the saloon for stance and front-end response without pre-loading the spring and ruining the damper’s working range. Through quicker direction changes the long wheelbase stops pitching, and brake bite improves because the front axle stays loaded instead of unweighting the rear under trail-braking.

About the Top Sport coilover

The Top Sport uses a 52mm monotube damper with a separated piston and a large oil capacity, which is what lets it hold damping consistency through repeat heat cycles on a circuit. 30 clicks of combined bump and rebound adjustment cover the spread between a fast B-road setup and a dedicated trackday tune without needing a spring change. Spring rates are matched specifically to the GJ chassis weight distribution rather than carried over from a generic kit, and pillow-ball top mounts replace the rubber OE bushings on the front struts to sharpen steering response and lock in camber under load. Construction is full T6061 aluminium on the lower brackets to keep unsprung mass down, with hard-anodised threads that survive a UK winter without seizing.

Fitment for the Mazda 6 (2012-2026)

This kit is fitted to the GJ1 and GL platform Mazda 6 / Atenza, covering saloon and Tourer estate variants from the 2012 launch through to the run-out cars. Petrol 2.0 and 2.5 SkyActiv-G and the 2.2 SkyActiv-D diesel are all supported on the standard fitment. Confirm your chassis prefix against the V5 before ordering if you have an early facelift car.
