XYZ Racing Street Advanced Coilovers — Jaguar XJ (X351) 6 CYL (Fr FORK) (OE FOR REAR AIR STRUT) 2010-2019

The Jaguar XJ (X351)’s aluminium monocoque keeps kerb weight low for a car of its length, but the standard air suspension is tuned for isolation first and body control a distant second – push it through a fast B-road and the nose floats under trail-braking while the rear feels disconnected from what the front axle is doing. The XYZ Racing Street Advanced coilover kit, built for the front "Fr Fork" strut mount, replaces that factory setup with a coilover unit aimed at owners who want the ride usable every day while sharpening how the car turns in and settles.

This kit is specified to retain the factory OE rear air strut, so it’s built for XJ owners who want the front end transformed without touching a rear air system that’s often still working fine and expensive to replace. Street Advanced is XYZ’s road-and-track-day spec, sitting between a comfort-first fitment and a full circuit setup.

What this coilover kit does for your 2010-2019 Jaguar XJ (X351)

Swap the front struts for this kit and the XJ’s nose stops diving into a roundabout under braking, because the damping and spring rate are matched rather than left to a factory compromise tuned around a soft ride. The 720-way damping adjustment lets you set the front end firmer for a good road or a track day, then back it off for the motorway commute the X351 was also built for. Front ride height is adjustable, so you can correct the nose-down stance that develops as the factory rear air struts age and settle, levelling the car and improving the geometry the front tyres work with. Turn-in sharpens noticeably on a car this size and weight, because much of the vagueness owners feel through the wheel comes from a front end under-damped for its mass, not from the chassis itself. On the road, a heavy luxury saloon changes direction with less lean and more feedback than the standard setup ever offered.

About the Street Advanced coilover

Street Advanced is XYZ Racing’s volume seller, and the spec reflects years of development rather than a single production run. XYZ’s professional team has tested the platform through international racing events, and lessons from that programme – spring rate selection, valving under repeated heat cycles, monotube reliability – feed into a kit built for road cars. The headline figure is 720 discrete damping settings, a genuinely fine adjustment range rather than the handful of clicks some road kits offer, so you can find a setting for a specific road or a specific track day instead of settling for close enough. It’s dual-purpose equipment: firm enough to be worth booking a track day around, compliant enough not to wear you down on the drive home. For a car like the X351, where the standard suspension leans heavily toward isolation, that range is what lets an owner shift the balance toward control without living with a harsh daily ride.

Fitment for the Jaguar XJ (X351) (2010-2019)

This kit is specified for the Jaguar XJ, chassis code X351, across the 2010 to 2019 production run, covering 6-cylinder variants that use the front "Fr Fork" strut mounting. It’s built to pair with the factory OE rear air strut, so confirm your car retains its original rear air suspension before ordering – this is a front-axle-focused fitment, not a full front-and-rear coilover conversion.
