XYZ Racing Top Sport Coilovers — Nissan SKYLINE RV37 400R 2019-2026

The RV37 400R is Nissan’s most focused Skyline in a generation – a 400ps twin-turbo GT built on the FM platform with the VR30DDTT positioned behind the front axle for a natural front-to-rear balance, yet delivered on suspension calibrated for long-distance comfort rather than committed driving. XYZ Racing’s Top Sport coilover changes that equation, bringing 30-50% greater damping over street specification alongside a 2 kg/mm spring rate increase that brings the chassis’s latent capability closer to the surface.

The Top Sport sits in the XYZ Racing range at the boundary between track-day readiness and daily usability. For an RV37 400R owner who runs circuit days occasionally but covers public-road miles the rest of the time, that calibration is the right one – firmer and more controlled than a touring setup without the uncompromising character of a full competition specification.

What this coilover does for your 2019-2026 Nissan Skyline RV37 400R

The FM platform’s longitudinal engine layout gives the 400R the raw ingredients for precise, balanced handling – the Top Sport’s higher damping and spring rates let that balance show. Pitch and roll under hard driving are suppressed by the firmed damping, keeping the VR30DDTT’s considerable torque feeding traction rather than managing body movement. Tyre contact improves as a direct result: the suspension absorbs large-bump impacts and suppresses the body oscillation that would otherwise unsettle the standard dampers on broken surfaces. Lower ride height shifts the 400R’s centre of gravity downward, sharpening turn-in and reducing lean through fast corners. The 2 kg/mm spring rate increase over street calibration is enough to provide circuit-capable structural firmness without creating a car that feels punishing on a public-road run.

About the Top Sport coilover

The Top Sport draws on XYZ Racing’s track development programme, with settings calibrated to cover both circuit sessions and the road miles that bracket them. Damping runs 30-50% above street specification – enough to control body movement under aggressive driving while retaining compliance over uneven surfaces that a harder setup would transmit directly into the cabin. Spring rates carry a 2 kg/mm increase over street calibration, providing the firmness the chassis needs on a circuit without transforming daily driving into a trial of endurance. XYZ Racing engineer the Top Sport to absorb the jolt of large bumps and suppress body shock, with the practical result of improved tyre traction and vehicle stability across a range of surfaces and speeds. The specification is explicitly rated for track-day use and aggressive driving – not as a marketing qualifier, but as a description of the use cases the damping and spring combination was developed around.
