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

The G20 P11 rode on Nissan’s Primera platform, and Infiniti tuned the factory dampers for a soft, isolated ride rather than the crisp turn-in enthusiasts kept looking for. Under the SR20’s mid-range pull, that softness shows up as body roll into a corner and a rear end that wallows over mid-corner bumps – exactly the trait this Street Advanced kit is built to correct, provided you’ve confirmed the φ90 rear bolt spacing on your car before ordering.

XYZ Racing’s Street Advanced coilover sits between a comfort-biased kit and a dedicated track setup: enough adjustment range to firm the G20 up for a fast road drive or the odd track day, without turning the daily commute into a chore. For a 24-year-old compact sedan that’s more often modified for handling than outright power, that balance is the point.

What this coilover does for your 1998-2002 Infiniti G20

Ride height adjustment lets you correct the G20’s factory-high stance and drop the centre of gravity, which sharpens turn-in and cuts the roll that the standard springs allow mid-corner. The damping adjuster – 720 distinct settings – gives you enough range to soften the ride for motorway miles one weekend and firm it up for a track day the next, without swapping parts. Because the kit is height- and damping-adjustable independently, you can set ride height for stance or clearance first, then tune compression and rebound separately to suit the SR20’s weight over the front axle. The result on the P11 chassis is a car that turns in with less lean and settles faster after a bump, rather than continuing to move once the input’s already been corrected.

About the Street Advanced coilover

Street Advanced is one of XYZ Racing’s longest-running and most widely fitted coilover lines, refined over successive seasons of development and validated through use in racing series worldwide before being carried across to road applications. It’s built specifically to cover both normal road use and track day driving on the same set of springs and dampers, rather than forcing a choice between the two. The 720-way damping adjustment is the headline spec – enough granularity to find a setting for daily comfort and another for a firmer track-day response, all from the same shock body. For a driver who wants genuine control over how the car behaves rather than a fixed factory compromise, this is the kit XYZ Racing points to as its core street-and-track offering.

Fitment for the Infiniti G20 (1998-2002)

This kit is built for the Infiniti G20 P11 chassis (chassis code IN04) across the 1998 to 2002 model years, specifically the variant with a rear shock bolt distance of φ90mm. Confirm the rear mounting spacing on your car against this figure before ordering, as P11-generation G20s were built with more than one rear bolt pattern and the wrong one won’t fit.
