We run Wavetrac front and rear differentials in our own GXPA16\/GZEA14 project cars, and they're the first upgrade we recommend once you've sorted tyres and alignment. The GR platform's AWD system relies on both diffs working together to put power down. The factory front diff is an open unit with no factory LSD option, and it's the weak link when you start pushing corner exit throttle on track or loose surfaces. In our experience the biggest gain from a front Wavetrac is reduced inside-wheel spin on corner exit, particularly on damp or bumpy roads where the factory diff just lets the inside tyre light up and scrubs off drive.\u003c\/p\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eShop by Vehicle\u003c\/summary\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/wavetrac-differentials-australia\"\u003eWavetrac Differentials Australia (full range)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/wavetrac-vw-golf-r\"\u003eWavetrac for VW Golf R\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/wavetrac-bmw-e-series\"\u003eWavetrac for BMW E-Series\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eShop by Product Type\u003c\/summary\u003e\n\u003cul\u003e\n\u003cli\u003eWavetrac Front Differential - Toyota GR Yaris \/ GR Corolla (GXPA16\/GZEA14): does most of the work, since the front axle carries more load under corner exit throttle on this platform.

An open diff sends power to whichever wheel has the least grip, which shows up as inside wheel spin on tight, bumpy Aussie backroads or when you're on the kerbs at The Bend. A Wavetrac ATB (automatic torque biasing) unit locks up progressively under load and unlocks smoothly on trailing throttle, so it doesn't fight you through slow, tight turns like some plate-type LSDs can. Compared against the factory setup, the difference is most obvious on damp roads and second-gear hairpins, where the GR Yaris and GR Corolla can otherwise spin an inside tyre and scrub off drive.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eFitment \u0026amp; Installation\u003c\/summary\u003e\n\u003cp\u003eThese are direct fitment units for GXPA16 GR Yaris and GZEA14 GR Corolla, front and rear. We recommend fitting both together where the budget allows, since the AWD system splits torque and a single upgraded diff only solves half the equation. Installation requires the diff housing to be opened, so factor in gearbox or diff carrier removal, and use fresh gear oil and factory hardware on reassembly. This isn't a bolt-on weekend job for most home garages; we'd rather see it done properly by a driveline specialist first time.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003ePair with the rest of your build\u003c\/summary\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/autotech-driveline\"\u003eAutotech Driveline components\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/blogs\/news\/wavetrac-vs-oem-differential\"\u003eWavetrac vs OEM Differential: what changes on the road\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eFAQ\u003c\/summary\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit both GR Yaris and GR Corolla?\u003c\/strong\u003e Yes, both share the GXPA16\/GZEA14 driveline architecture and use the same Wavetrac units front and rear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need the front and rear diff, or just one?\u003c\/strong\u003e Front first is the priority for most road and track drivers, since it's doing more of the work on corner exit.
