XYZ Racing Tarmac Rally Coilovers — Infiniti FX35/37 S51 4WD (Modified Rear Integrated) 2008-2013

The S51-generation FX35/37 carries close to two tonnes of V6 and all-wheel-drive hardware on a body taller than most cars it will overtake on a closed road. That height and mass work against it the moment the tarmac gets uneven – crests, compressions and mid-corner ripples load the double-wishbone front and multi-link rear hard, and a soft factory damper lets the body roll and pitch faster than the AWD system can react to it. XYZ Racing’s Tarmac Rally coilover is built to keep that mass under control when the stage surface stops being smooth.

This is a purpose-specific spec for sealed-stage tarmac rally use, not a generic lowering kit dressed up with rally branding. It’s set up to absorb the hit from broken edges, patched sections and camber changes without kicking the body off line, so the FX’s weight stays where the driver put it through a fast right-hander.

What this coilover brings to your 2008-2013 Infiniti FX35/37 S51 4WD (Modified Rr Integrated)

On a car this heavy, the biggest gain is control over how the body reacts when a wheel meets a bump mid-corner. The damper is tuned to absorb the jolt from big surface breaks rather than transmitting it straight into the chassis, which keeps the tyre’s contact patch loaded instead of skipping across the road. That matters more on the FX than on a lighter rally platform – less unsprung mass movement means the AWD system can keep putting power down through compressions instead of hunting for grip. Lowering the centre of gravity from the factory ride height also cuts the body roll that a tall crossover chassis is naturally prone to under hard direction changes, and the reduction in shock body movement translates directly into a more stable rear end over the kind of broken, patched tarmac that closed-road stages are actually made of.

About the Tarmac Rally coilover

XYZ Racing built the Tarmac Rally line specifically around uneven, imperfect road surfaces rather than the smooth, consistent camber of a circuit. The damper is calibrated to soak up impacts from larger bumps and surface breaks without letting that energy travel into the body shell, which is what keeps the car settled instead of skittish when a stage throws a rough patch mid-corner. Suppressing that shock body movement is also what protects tyre traction – a chassis that stays composed keeps its contact patches working instead of unloading them over every ripple. The valving and spring settings on this range come directly from XYZ’s own tarmac rally programme, carried over from the damper behaviour the team found necessary to hold a line at speed on real stage surfaces rather than derived from a road-going baseline and softened for sale.
