Toyota launched the GR Yaris in the UK in 2020, built specifically to homologate a competitive car for the World Rally Championship. It's powered by the G16E-GTS, a 1.6-litre turbocharged three-cylinder engine, sending drive to all four wheels through the GR-Four system - a layout that doesn't appear anywhere else in the standard Yaris range.

Suspension and chassis parts make up the largest share of the range here, ahead of exhaust and engine/tuning components, which reflects how much the AWD system and shorter wheelbase change the car's balance compared with a front-wheel-drive hatch of similar size. BC Racing coilovers are a common starting point. Cooling parts, while a smaller category by volume, are worth calling out specifically: a small-capacity turbocharged engine working hard is more cooling-limited than its size suggests, and AIRTEC is well represented here.

Beyond suspension and cooling you'll find exhaust systems from brands including Cobra Sport, engine and tuning components, drivetrain and clutch parts (reflecting the extra driveline complexity of a four-wheel-drive layout), braking upgrades and a small range of interior parts.
