XYZ Racing Super Sport Coilovers — Infiniti M25/ M35/ Q70 Y51 FUGA 2010-2026

The Y51 platform is a big, rear-drive (or AWD) executive saloon with a long wheelbase, a heavy nose courtesy of the VQ-family V6, and OEM damping tuned for hushed motorway miles rather than B-road commitment. That softness is exactly what owners notice first when they start driving the Infiniti M25, M35h or Q70 the way the chassis is genuinely capable of being driven – body roll on turn-in, dive under braking, and a ride height that leaves the arches looking under-filled.

The XYZ Racing Super Sport coilover for the Infiniti M25/ M35/ Q70 Y51 FUGA tackles all three at once. It is the fast-road-with-occasional-track-day spec in the XYZ range – a height-adjustable, 36-way damper that retains real-world compliance for daily use on patched UK tarmac.

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

Drop the Y51 onto its Super Sports and the chassis tightens up in a way the factory dampers never let it. The 36-way damping adjustment is the headline feature: wind clicks off for a firmer, flatter front end when you want the nose to bite into a roundabout, or wind them back on for long motorway stints when you’d rather the saloon swallow expansion joints quietly. Ride-height adjustment lets you set the stance without the arch gap that defines a stock Fuga, while preserving enough travel for British road surfaces. Under braking, the reduced dive keeps weight more evenly distributed across the front tyres, so the big saloon stops with noticeably more composure. The result is a Y51 that finally drives like the sports-luxury car the spec sheet always promised.

About the Super Sport coilover

The Super Sport damper is engineered to eliminate the discomfort that usually comes with bumps and broken surfaces – a deliberate brief that separates it from harder track-only kits. Ride height is adjustable at the strut, and damping is set across 36 detented positions so the same hardware can be configured for a quiet commute and then retuned for a weekend on a circuit without swapping parts. That breadth is the point of the Super Sport tier: it is a high-performance damper built for both weekend race use and daily driving, rather than forcing the owner to pick one. Construction follows XYZ’s standard coilover layout, and the kit covers the full Y51 production span from the original M25/ M35h through to the late Q70 facelift cars.
