XYZ Racing Top Sport Coilovers — Infiniti EX35 4WD (Modified Rear Integrated) 2007-2012

The EX35’s 4WD platform carries more hardware over the rear axle than a standard RWD Infiniti, and on the standard dampers that extra mass shows up as float through direction changes and a rear end that’s slow to settle after a mid-corner bump. XYZ Racing’s Top Sport coilover is built for exactly this kind of car: one that sees a track day now and then but still has to cover motorway miles and school-run duty in between.

Damping is raised 30-50% over the standard rate here, paired with a spring rate roughly 2kg/mm firmer than a factory setup, so the modified rear-integrated rear end stops wallowing without turning the ride into a punishment. On the EX35’s 4WD chassis that translates into a car that changes direction with noticeably less lag between input and response.

What this coilover does for your 2007-2012 Infiniti EX35 4WD (Modified Rr Integrated)

The firmer spring and damping combination controls the pitch and roll that the EX35’s crossover height and 4WD driveline mass otherwise generate, so weight transfer under braking and turn-in is quicker to settle and easier to read from behind the wheel. Big compressions – potholes, kerb strikes, the mid-corner bumps a track day throws up – get absorbed rather than kicked straight through to the chassis, which keeps the tyre in contact with the road instead of skipping across it. That extra contact patch consistency is where the traction gain actually comes from: less energy lost to unloading, more of it going into grip. The rear-integrated modification on this fitment means the kit is matched specifically to how the EX35’s rear end has been set up, not a generic drop-in, so the damping and spring numbers apply cleanly front to rear.

About the Top Sport coilover

XYZ Racing developed the Top Sport line directly from its Top Sport racing programme, then dialled the settings back from full competition spec to something that still works as a daily driver. The core idea is straightforward: increase damping force by 30-50% and spring rate by around 2kg/mm over a standard road setup, which gives the kit enough control to shrug off big hits – a heavy kerb strike, a poorly-repaired B-road – without the shock body kicking back at the chassis or unsettling the car. That extra control is what keeps the tyre loaded and gives the EX35 the planted, predictable feel through a corner that a soft factory setup can’t match. It’s built for track day use and a more aggressive driving style, but the spring and damping rates are chosen to stay usable outside the circuit, which is why it suits a car that’s still doing road miles between sessions.

Fitment for the Infiniti EX35 4WD (Modified Rr Integrated) (2007-2012)

This kit is built for the Infiniti EX35 4WD in its modified rear-integrated configuration, chassis code IN17, covering the 2007 to 2012 model years. The rear-integrated spec means the coilover is matched to this specific rear-end arrangement rather than a generic 4WD EX35 setup, so confirm your car falls within this year range and drivetrain configuration before ordering.
