XYZ Racing Top Sport Coilovers — Toyota YARIS XP90 Modified Rear Integrated 2005-2011

The Yaris XP90’s short wheelbase and low kerb weight make it eager to change direction, but that same lightness means the factory dampers run out of control long before the front tyres run out of grip. XYZ Racing’s Top Sport coilover kit for the Toyota Yaris XP90 (2005-2011) replaces that soft factory tune with settings built around occasional track days and daily use in between. It’s a full coilover system, not a lowering spring, so ride height, spring rate and damping all move together instead of fighting each other.

On a car this light, spring and damper changes are felt immediately rather than masked by mass – this Top Sport spec adds enough body control for a trackday session without making the Yaris uncomfortable as daily transport.

What this coilover does for your 2005-2011 Toyota YARIS XP90 Modified Rr Integrated

Fitted to the XP90, the kit lifts spring rate and damping roughly 30-50% above the standard road setting, which keeps the nose settled under braking into a corner instead of diving and loading the outside front tyre unevenly. The stiffer rate also stops the rear stepping out of line over mid-corner bumps, since the extra control absorbs the jolt from broken tarmac rather than letting it upset the rear axle mid-turn. You’ll feel less roll through direction changes, sharper turn-in response, and a front end that holds its line under trail-braking instead of washing wide. Ride height is adjustable independently of spring preload, so you can drop the Yaris for a lower centre of gravity without compressing the springs into their travel and losing compliance over kerbs and drain covers.

About the Top Sport coilover

Top Sport sits above XYZ Racing’s street-focused ranges and below the full competition coilover – the settings come directly from the brand’s own Top Sport racing programme rather than a generic road tune. Compared with a standard street coilover, damping force is raised by around 30-50%, or the spring rate is stepped up by roughly 2kg/mm, depending on the application. That extra control is there to soak up hard hits from broken road surfaces and kerbs without the shock body kicking back through the chassis, which keeps the contact patch loaded and improves tyre traction under acceleration and braking rather than letting the tyre skip over imperfections. The result is a kit tuned for stability at speed – body movement is checked hard enough for aggressive driving and the odd track session, while remaining a bolt-in system rather than a race-only part needing supporting chassis work.

Fitment for the Toyota YARIS XP90 Modified Rr Integrated (2005-2011)

This kit is specced for the Toyota Yaris XP90, chassis code TO64, across the 2005 to 2011 production run, including the Modified Rr Integrated rear-end configuration covered by this listing. Confirm your registration falls within that build window before ordering, since Toyota revised the XP90 platform more than once across its run.
