XYZ Racing Circuit Master Coilovers — Infiniti G20 P11 (Rear Bolt Distance φ90) 1998-2002

The G20 P11’s front-wheel-drive layout puts more weight over the nose than a rear-drive rival of the same era, and under sustained circuit loading that shows up as front tyre scrub and body roll eating into steering feel through fast direction changes. XYZ Racing’s Circuit Master coilover is built around a monotube damper with three external adjustment knobs, giving 9,720 individual damping combinations to keep the outside front tyre flat and loaded through repeated laps rather than letting it roll onto the sidewall as speeds climb.

This fitment covers the P11 built with the φ90 rear bolt-spacing subframe, so the rear damper mounts and spring perches match that specific rear end rather than a generic G20 kit. Circuit Master is XYZ Racing’s dedicated circuit line, aimed at owners who want the car to hold its line for a full 20-minute session, not just one clean warm-up lap.

What this coilover does for your 1998-2002 Infiniti G20

Height-adjustable perches let you drop the centre of gravity and correct the nose-down stance that comes with age on the standard springs, sharpening turn-in on a chassis that’s naturally reluctant to rotate. The monotube damper resists heat fade better than the twin-tube unit it replaces, so damping force stays consistent as the oil warms up over a session rather than softening halfway through. Stiffer spring rates cut the dive under trail braking that a nose-heavy FWD platform is prone to, giving you a more stable platform to load the front tyres into a corner. With three knobs and 9,720 damping combinations, you can firm up compression for a smooth circuit surface, then back off rebound if the rear starts skipping over kerbs. The result is a G20 that changes direction with less roll and less understeer creep than it left the factory with.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s range, developed and run by XYZ’s own racing teams across international circuit competition rather than designed on paper alone. The monotube body and three-way external adjustment give 9,720 possible damping combinations, letting a driver tune compression and rebound independently to suit a given track surface or tyre compound. Internally, damping oil is metered through a deliberately small-bore passage – a design choice that trades a slight audible tick over sharp bumps for tighter, more repeatable damping control at speed. That noise is expected behaviour on rough surfaces, not a fault, and it’s largely irrelevant on the smooth tarmac the kit is actually engineered for. The construction and adjustment range are aimed squarely at drivers chasing consistent lap times over a full circuit session, not a one-off fast road blast.

Fitment for the Infiniti G20 P11 (1998-2002)

Built specifically for the P11-generation G20 sold from 1998 to 2002, chassis code IN04. This kit is matched to the φ90 rear bolt-distance subframe variant – check your car’s rear mounting spacing against this spec before ordering, as the P11 was produced with more than one rear bolt pattern across markets.
