XYZ Racing Circuit Master Coilovers — Infiniti G35 4D (Modified Rear Integrated) 2002-2006

The G35 sedan’s front-midship platform sits the VQ35DE well back behind the front axle line, and on the factory dampers that near-even weight split still lets the nose dive under trail-braking while the rear steps out earlier than the chassis’ balance really allows. XYZ Racing’s Circuit Master coilover is built around sustained circuit lap-time work rather than a single quick lap, so it’s aimed at G35 4D owners doing repeat sessions, not the occasional trackday outing.

This fitment covers the modified rear-integrated variant of the IN06 chassis, which means the kit is matched to the rear geometry XYZ measured on the car rather than a generic RWD template. On a platform where the multi-link rear is doing most of the cornering work, that distinction is the difference between a coilover that merely bolts on and one that actually controls the axle.

What this coilover does for your 2002-2006 Infiniti G35 4D (modified Rr Integrated)

With 9720 damping combinations spread across 3 external knobs, you can separate low-speed compression from rebound instead of chasing one shared setting, which matters on the G35 because trail-braking rotation and mid-corner rear grip pull in different directions. Softening low-speed compression keeps the front tyres loaded as you release the brake into a corner, while firming rebound stops the rear from pattering over kerbs on a circuit like Cadwell Park or Snetterton. Ride height adjusts independently of that damping range, so you can drop the G35’s centre of gravity for track days and wind it back up for road use without touching spring preload. The net change on this chassis is a car that turns in with less of the nose-heavy push the standard dampers allow, and a rear axle that stays settled through direction changes instead of stepping out under power.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s range, developed and run in by XYZ’s own racing teams across international circuits rather than built purely to a spec sheet. The headline figure is 9720 individual damping combinations, split across 3 external adjustment knobs so compression and rebound can be tuned apart from one another instead of blended into a single setting. That range comes from a small-orifice oil-passage design inside the damper, which is precise under the loads a circuit session generates but can produce a faint noise over sharp road bumps and expansion joints – that’s the valving working at circuit-bump frequencies, not a fault, and it’s a trade-off XYZ made deliberately for a track-first damper. Construction is aimed at repeat-session consistency rather than a single fast lap, which is why the range is pitched at drivers doing sustained circuit work rather than an occasional sighting lap on the road.

Fitment for the Infiniti G35 4D (modified Rr Integrated) (2002-2006)

This kit is built for the Infiniti G35 4D, chassis code IN06, across the 2002 to 2006 model years. It’s specified for the modified rear-integrated variant of that chassis, so confirm your car’s rear suspension matches this configuration before ordering rather than assuming the standard IN06 mount pattern applies.
