Wavetrac Rear Differential Toyota GR Yaris / GR Corolla (GXPA16/GZEA14)

Wavetrac Rear Differential - Toyota GR Yaris / GR Corolla (GXPA16/GZEA14)

The Wavetrac Differential is a genuinely modern take on the helical torque biasing diff — designed from scratch by Autotech Driveline in the USA. Unlike conventional limited slip units, the Wavetrac includes patented cam technology that prevents the diff from acting like an open unit under zero axle load conditions, keeping drive going to the wheel with grip when it matters most. It's a strong choice for the Toyota GR Yaris and GR Corolla, whether you're chasing lap times or daily spirited driving.

This listing covers the Wavetrac rear differential (SKU: 94.309.170WK) suited to the Toyota GR Yaris (GXPA16) and Toyota GR Corolla (GZEA14) platforms.
