XYZ Racing Street Advanced Coilovers — Mazda 6 / ATENZA (GJ1-GL) 2012-2026

The GJ-generation Mazda 6 carries a lot of its mass over the nose – especially with the 2.2 SkyActiv-D up front – and the factory damping was deliberately soft, letting that weight float over crests and the long body lean through fast sweepers. The XYZ Racing Street Advanced coilover for the Mazda 6 / Atenza (GJ1-GL) is built to take that slack out of the chassis while keeping the refinement that made the car worth buying in the first place.

This is the adjustable-comfort end of the XYZ range: a height-and-damping setup aimed at the enthusiast who drives the same SkyActiv saloon or Tourer to work all week and wants it to feel honest on a back road or the occasional track day. You set the stance you want, then tune how firm it rides.

What these coilovers do for your 2012-2026 Mazda 6 / Atenza (GJ1-GL)

Drop the ride height and you immediately lower the GJ’s centre of gravity, which calms the body roll and the nose-dive under braking that the standard springs allow. The 720-way damping adjustment is the headline feature here – it lets you run the car soft and supple for the commute, then wind in firmer rebound control before a track session without touching the springs. On a long-wheelbase estate that means tauter turn-in and a flatter attitude mid-corner, with the floaty secondary ride over motorway undulations brought back under control. Tyre contact stays more consistent, so the front axle bites earlier and the understeer the platform is known for softens noticeably.

About the Street Advanced coilover

The Street Advanced is XYZ Racing’s most popular kit, refined over years by their development team and validated through international race programmes before reaching production. It is engineered specifically to straddle two jobs – everyday road use and the odd track day – rather than committing fully to either. The 720 individual damping settings give a genuinely wide window of adjustment, so the same hardware suits a soft daily setup or a tighter circuit configuration. It is positioned as essential kit for drivers who care about both pace and control, and the construction reflects that dual brief: durable enough for British roads, adjustable enough to reward someone who likes to fiddle.

Fitment for the Mazda 6 / Atenza (GJ1-GL) (2012-2026)

This kit is matched to the GJ1-GL chassis Mazda 6, sold in the UK as the 6 and in Japan as the Atenza, across the full 2012-2026 production span. It covers the saloon and Tourer body styles on the SkyActiv platform, including the post-2018 facelift cars.
