XYZ Racing Street Advanced Coilovers — Infiniti M25/ M35/ Q70 Y51 FUGA 2010-2026

The Y51 FUGA sits in an awkward spot for the suspension aftermarket – a 1.8-tonne rear-drive luxury saloon with VQ or VK power, a long wheelbase, and OEM dampers tuned for hushed cruising rather than corner exit. The Street Advanced coilover for the Infiniti M25, M35 and Q70 Y51 FUGA is built to keep that big-saloon refinement on a B-road while tightening the body control the factory air-assisted setup was never going to deliver.

For a 2010-2026 Y51 owner who wants the car to settle on a motorway, then hold a line through a fast sweeper without the nose washing wide, this is the XYZ kit that earns its money. It is the Street Advanced spec – daily-driven, adjustable, and engineered around the platform’s real weight rather than a generic saloon template.

What this coilover does for your 2010-2026 Infiniti M25/ M35/ Q70 Y51 FUGA

Drop the Y51 onto height-adjustable spring perches and you address the first thing every owner notices: the wallowy ride height and the visible arch gap that ruins the car’s lines. Lower the ride, then dial the 720-way damping circuit firmer at the front to take the float out of the nose under brakes, and softer at the rear to stop the long-wheelbase chassis from skipping mid-corner. The result is a saloon that still rides well enough for the school run on Monday but stops pitching forward when you brake hard for a roundabout. Body roll drops without making the cabin crashy, and the steering loads up properly off-centre – a meaningful upgrade on a car this size and this nose-heavy.

About the Street Advanced coilover

Street Advanced is XYZ’s road-and-occasional-track spec, refined over years by the XYZ professional team and validated in races worldwide before it ever reached the catalogue. The headline number is 720 damping settings on a single adjuster, which is the working range a road driver actually uses – enough resolution to separate a comfort setup from a B-road setup from a track-day setup, without the complexity of separate bump and rebound circuits. Construction is built around full ride-height adjustability independent of spring preload, so you can sit the car at the height you want without sacrificing damper stroke. It is positioned by XYZ as the indispensable kit for drivers chasing speed and control on the road, and it is the most popular product in their range for exactly that reason: it covers normal road use and occasional track work in one purchase.

Fitment for the Infiniti M25/ M35/ Q70 Y51 FUGA (2010-2026)

This kit is built specifically for the Y51 platform – chassis code IN16 – covering the M25, M35 and Q70 badges and the JDM FUGA equivalent from 2010 through to 2026. Confirm your chassis plate reads Y51 before ordering; the earlier Y50 FUGA and the M35/M45 from the previous generation use a different mounting setup and are not compatible.
