XYZ Racing Top Sport Coilovers — Infiniti G20 P11 (Rear Bolt Distance φ172) 1998-2002

The G20 P11’s front-wheel-drive layout was tuned by Nissan’s engineers to punch above its badge – a taut, nose-heavy platform with steering and geometry that reward a driver willing to trail-brake into a bend, hobbled from the factory by dampers calibrated for cushioning rather than body control. The XYZ Racing Top Sport coilover for this Infiniti G20 P11 (1998-2002), built for the φ172 rear bolt distance variant, rebuilds that geometry around spring and damper rates suited to a car that does the commute on Friday and a track day on Saturday.

Where the standard set lets the nose dive under braking and the rear squat off the line, Top Sport’s firmer control keeps the P11’s chassis flatter through direction changes without turning the daily drive into a chore.

What this coilover does for your 1998-2002 Infiniti G20

Fitting this kit lifts damping force by roughly 30-50% over the standard street calibration, or adds around 2kg/mm to the spring rate depending on the setting chosen, so the body stops wallowing over mid-corner bumps and starts transferring load to the tyres instead of the bushings. On the G20’s nose-heavy chassis that translates directly into sharper turn-in, because the front end stops compressing and rebounding through a corner and starts holding a consistent contact patch. Big hits – expansion joints, broken tarmac, speed humps taken with intent – get absorbed rather than kicked through the cabin, which keeps the car composed on the sort of B-road that punishes a soft factory setup. The net effect is a car that puts more of its power down out of slow corners and stops leaning on its outside front tyre under trail-braking.

About the Top Sport coilover

Top Sport is XYZ Racing’s setting for owners who want more than a fast-road spring rate but don’t want to build a dedicated track car. Damping is increased 30-50% over the street baseline, and the spring rate can be stepped up by around 2kg/mm, giving the kit the range to handle a rough B-road one day and a track day the next without a second set of springs. The calibration comes directly from XYZ Racing’s own Top Sport competition programme, carried over into a road-usable damper rather than diluted for comfort. Construction keeps the shock body under control through repeated heavy inputs – big bumps, kerbs, aggressive direction changes – so the tyre stays loaded and the car holds its line instead of skating off camber. It’s built specifically for track day use and for drivers who push the car hard on the road, not for a soft, comfort-first ride.

Fitment for the Infiniti G20 P11 (1998-2002)

This kit is built for the Infiniti G20 P11 (chassis code IN03) across the full 1998-2002 production run, specifically for the rear bolt distance φ172 configuration. Confirm your rear hub bolt spacing against this figure before ordering, since the P11 was produced with more than one rear mounting spec across its production life and the wrong one will not bolt up.
