XYZ Racing Circuit Master Coilovers — Infiniti M35 4WD (Modified Rear Integrated) 2006-2010

The M35’s ATTESA all-wheel-drive hardware puts a front differential and prop shaft under that VQ35DE V6, shifting weight forward and loading the modified rear subframe in a way the standard rear-drive Fuga-based chassis never sees. XYZ Racing’s Circuit Master coilover is built for exactly that kind of car: a big luxury sports saloon that’s heavier than it looks and needs a suspension platform that can hold a consistent line through repeated hot laps rather than one quick attack pass.

On the 4WD M35, that means controlling body roll through the extra unsprung mass at the rear axle while keeping the front end planted under trail-braking into slower corners. The Circuit Master is aimed squarely at drivers doing sustained circuit lap-time work in this car, not a one-off track day where a fast-road spring rate would do.

What this coilover does for your 2006-2010 Infiniti M35

With the transfer case and modified rear-integration points adding weight over the rear axle, the M35 4WD needs damping that can settle quickly after direction changes without ballooning ride height under load. The Circuit Master’s 3-way adjustment knobs let you separate low-speed compression from rebound, so you can firm up body control through the M35’s heavier rear end while still letting the tyre track bumps mid-corner. Spanning 9,720 individual adjustment combinations, the range is wide enough to move from a stiff qualifying-style setup to something more usable across a full session without swapping hardware. Ride height is adjustable independently of damping, useful for correcting the front-heavy stance the AWD driveline gives this generation of M35.

About the Circuit Master coilover

The Circuit Master sits at the top of XYZ Racing’s range, built for cars that spend real time on circuit rather than the occasional B-road blast. Construction uses a small oil-passage design through the 3 damping knobs, giving fine control over compression and rebound independently; on rough kerbs or big bumps this can produce a faint noise from oil moving through the smaller passage, which is expected and not a fault on a track-focused damper. XYZ Racing tests the Circuit Master through its own racing programme, and the 9,720-way adjustment window is there so a team or owner can retune between sessions rather than living with a single compromise setting. It’s a damper designed around circuit surfaces and sustained load, not everyday ride comfort.

Fitment for the Infiniti M35 (2006-2010)

This kit is built for the AWD Infiniti M35, chassis code IN10, model years 2006 to 2010, with rear mounting engineered for the modified, integrated rear geometry that this all-wheel-drive variant uses. Confirm your M35 is the 4WD version before ordering, as the rear subframe and shock mounting differ from the rear-drive car.
