XYZ Racing Top Sport Coilovers — Nissan SKYLINE V35 (Modified Rear Integrated) 2003-2006

The V35 Skyline’s independent multi-link rear was reworked for this modified Rr Integrated fitment, and it’s a chassis that rewards a coilover set-up rather than a soft factory spring. Push it into a fast B-road or a track day sighting session and the standard geometry lets the body roll before the rear axle settles, blunting the turn-in this platform is actually capable of. The Top Sport kit is built for exactly that gap between daily use and the odd track outing.

XYZ Racing’s Top Sport spec increases damping by 30-50% and lifts spring rate by roughly 2kg/mm over street settings, so the kit absorbs a bad B-road surface without transmitting every ridge into the cabin, while controlling body movement once you’re pushing on a circuit. It’s the spec XYZ built from its own Top Sport racing programme, tuned for track day and aggressive driving rather than outright competition.

What this coilover does for your 2003-2006 Nissan SKYLINE V35 (Modified Rr Integrated)

Fitted to this V35 Skyline, the raised spring rate and damping curve keep the rear multi-link geometry working through a corner instead of collapsing into roll, so the car turns in with less delay between your steering input and the front axle loading up. Over broken tarmac the extra 30-50% damping absorbs the jolt from potholes and expansion joints before it reaches the body, and that same control suppresses the shock-body movement that otherwise breaks rear tyre contact under load. The result on the V35 is a car that puts power down cleaner out of a bumpy apex and holds a line under trail braking instead of pattering wide. For a modified Rr Integrated example already carrying aftermarket rear hardware, matching spring rate to that set-up matters more than on a stock rear end, and this kit’s uprated rate is calibrated with that in mind.

About the Top Sport coilover

XYZ Racing’s Top Sport line sits above their street-focused kits, built around a damping and spring package roughly 30-50% firmer than road settings. That step up is deliberate: it’s there to soak up big hits – potholes, kerbs, mid-corner bumps – without the shock body kicking back and unsettling the chassis, which in turn keeps the tyre’s contact patch loaded through the impact rather than skipping. Every valving curve in the range traces back to XYZ’s own Top Sport racing programme, so the settings aren’t a generic off-the-shelf damper tune but one shaped by actual circuit use. The stated aim is vehicle stability under hard driving, which is why the kit is pitched at track day regulars and drivers who push on aggressively on the road, rather than at a comfort-first daily commute. On the V35 platform this translates into a set-up that’s firm enough to control the chassis at pace but still built around a street-usable damping range, not a full race-only spec.
