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

The 4WD M35 doesn’t drive like its rear-wheel-drive sibling. Power sent to the front axle and a rear end built around a modified, integrated suspension layout change how load moves through the car under trail-braking and hard direction changes, and the factory dampers were tuned for isolation, not control. XYZ Racing’s Top Sport coilover kit is built for owners who want that big Infiniti saloon to hold its line on an occasional track day without turning the daily commute into a chore.

This is a street-and-track dual-purpose setup, not a stripped-out race kit. It’s aimed at the M35 owner who wants sharper turn-in and less pitch under braking on a track day, then wants the car to ride properly on the way home.

What this coilover kit does for your 2006-2010 Infiniti M35

Damping is stepped up 30-50% and spring rate by roughly 2kg/mm over the standard street setting, which is enough to control the M35’s mass through direction changes without turning the ride brittle on UK B-roads. That extra damping force and spring rate keep the tyre’s contact patch loaded more consistently over broken tarmac, so you get more usable traction out of corners rather than a wheel skipping over the surface. Big compressions – a mid-corner ridge, a compression at a roundabout exit – get absorbed rather than kicked through the chassis, which keeps the body settled and the driver confident in what the car’s about to do next. On the 4WD car specifically, with its modified rear-integrated geometry, that added control at the rear axle matters as much as anything happening up front.

About the Top Sport coilover

XYZ Racing developed the Top Sport range directly from its circuit racing programme, carrying the damping and spring settings learned there into a kit that’s still usable on the road. The valving sits between XYZ’s full track kits and its street-focused ranges, giving the M35 noticeably firmer body control than standard without the harshness that a dedicated race setup would bring to a daily-driven saloon. It’s built to take aggressive driving and repeated track-day sessions in its stride, with settings chosen specifically to suppress body movement under load and keep the tyre working rather than skating.

Fitment for the Infiniti M35 (2006-2010)

This kit is engineered for the 4WD Infiniti M35 (chassis code IN10) with the modified, rear-integrated suspension configuration, covering the 2006 to 2010 model years. Confirm your car is the 4WD variant with this rear-end specification before ordering, as the front-drive-derived rear geometry differs from the standard rear-wheel-drive M35.
