The Outback BS was built as a raised, load-carrying version of the Legacy platform, not a corner-carver, so the factory dampers were never asked to control body roll at circuit speeds. Fit XYZ Racing’s Circuit Master coilovers to a 2014-2019 Outback BS 4WD and that higher factory ride height stops working against the symmetrical all-wheel-drive layout underneath it, giving a genuinely low centre of gravity instead of the wagon’s cross-country stance.
Circuit Master is XYZ Racing’s dedicated lap-time coilover, built for sustained circuit work rather than a single fast road run. On a wagon-bodied AWD platform like the Outback, that distinction matters: the kit has to hold its ride height and damping character through a full session, not just the first flying lap, while still coping with the extra mass an AWD wagon carries into every corner.
What this coilover does for your 2014-2019 Subaru Outback BS 4WD
Dropping the Outback BS onto Circuit Master coilovers lowers the car’s centre of gravity and firms up the body control that the standard cross-country-tuned suspension was never set up to provide. With 9,720 damping combinations across the kit’s 3 external adjustment knobs, you can run the front and rear independently to suit how the Outback’s AWD system shifts load between axles under braking and on corner exit, rather than accepting one compromise setting front to back. Ride height is adjustable independently of spring preload, so you can bring the wagon’s factory-high stance down to something that actually matches a circuit-day track width without touching the spring rate you’ve chosen for the car’s weight. The result on this chassis is less of the nose-dive and body roll the Outback shows on standard suspension, and a platform that transmits what the AWD system is doing underneath you instead of masking it in wallow.
About the Circuit Master coilover
Circuit Master sits at the top of XYZ Racing’s range, developed alongside the brand’s Racing Spec, Drift Spec and Tarmac Rally coilovers but tuned specifically for repeated circuit lapping rather than a single discipline like drifting or stage rally work. XYZ Racing’s own racing teams have run and tested the kit internationally, and that circuit mileage is where the 3-knob, 9,720-way adjustment range comes from – enough range to retune the car between a tight, bumpy club circuit and a fast, smooth one without swapping parts. The knobs work through a small internal oil-hole design, which is precise for damping control but does mean you may hear a faint noise from the dampers over sharp road bumps; that’s the valving doing its job, not a fault, and it’s irrelevant on the smooth circuit tarmac this kit is built for. Construction is monotube, chosen for consistent damping force as oil temperature rises through a session, which is exactly the failure mode a soft, comfort-tuned wagon damper hits first.
Fitment for the Subaru Outback BS 4WD (2014-2019)

Because its 3 adjustment knobs with small oil hole design, when driving through big bumps, the coilover oil will go through small passage which might cause some small noise. This is normal situation. This product is made for circuit tracks and there will be no concern for bumps on the tracks.

Every XYZ Racing coilover kit ships with the upper mounts listed below for your exact chassis — no extra parts to source.
Front
Pillow ball + rubberP+Pillow-ball upper with a rubber insert — adds steering precision and camber adjustability while keeping some of the factory mount’s harshness damping.
Hardened rubberRHardened rubber upper — firmer than the factory bush for tighter response while retaining road-friendly noise and vibration isolation.
Rear
AluminiumAAluminium upper mount — a stiff, lightweight housing that locates the damper precisely and resists flex under load.
